Does anyone know that how far I can use this machine to measure temperatures for HVAC? In our factory, the cooler air comes from about 10 ft high.

Yes it can measure temperatures from 10 ft away. Just remember that the sensor is 1" diameter for every 12" of distance between the gun and the target. So, in your case, the vent should be bigger than a diameter of 10".

It'll easily and accurately do that. My iffice is in an unfinished suite and the HVAC is almost 20' up and it gave me the same measure that the computer system did via remote on my laptop. I use it lots when I gave complaints in the offices where they say they are either too hot or too cold. Furniture fixtures are akmist never desugned with HVAC flow in mind and the ladies also dont like wearing layers so this backs me up when theyve asked for a specific tempAnd we set the computer for that and they complain. Cant argue with a digital lazer readout! Hope this helps. I love the dang thing! Even use mine for external barbie temps when slow cooking or smokong. Blessings, enjoy.

The instructions state that the farther away you are, the larger the area will be that you are measuring. In my house I read the hvac registrars in an 8 ft ceiling no problem. But if it's a precision reading you are looking for (ie temp of a small area) it may not be best. I would think all hand helds would have the same issue though.

I have measured temperatures on a 10 foot ceiling. Seems accurate at that distance.

I'm using mine on a patio as a slide in under an outdoor kitchen cabinet. Make sure you have about 4 inches around for air flow. This unit has the condenser built in the left and right sides and dissipats the heat unlike a fan blowing air across the condenser on your home frig. What I did do is take the 1/2 inch shipping foam that was in the box and duct tape it to the back and top to help insulate the box a little. Just dont cover any part of the outside that feels warm after it's plugged in. Here is something I want to warn you about but is no big deal. When the box is cold and say you go to get a drink out of it. After you close the door it forms a tight vacuum and makes the door almost impossible to open unless you wait 3 or 4 min. I do HVAC repair and have have seen this same thing happen on walk-in coolers trapping people. You need to make a way for the vacuum to be relieved. What I did was take a 2 inch piece of thermostat wire (this wire is about 1/2 the size of a cloths hanger) tapped it the top and bent it over to go between the refrigerator box and the door gasket. This little wire will allow the vacuum inside to equalize and you can open the door within 15 to 20 seconds and it wont bother the temperature. Buy the way this frig can freeze a bottle of pop if you set it to cold. My control is setting around 5 O'clock and running around 32 degrees. I leave it outside but unplug it in the winter. Good Luck

Charles,The unit has been a little disappointing, but not enough to return it. The humidity it measures is about 15% off, so I just compensate for that. If you set it for 60%, the compressor and fan will run until it reaches 57%, which seemed a bit odd to me. The unit does not measure temp, as was advertised. The fan does shut off once it has overachieved on the desired setting.

I'm not exactly sure. I had it controlling a fan in a green house that was getting way too warm. However, once I got this wired up and working the green house never got over 100 F. On the low end, I'm not at all sure since I only used it in the summer. It's fairly sturdy in the construction and uses some old school tech. I'd be surprised if it would stop working at a high temperature unless it started to melt the plastic.

Assuming that is 25' x 25' x 10', I believe 1 unit would be challenged if you're in Northern Alberta - checking some weather info for Fort McMurray (a guess), I see 'average' lows of -10 F and minimum lows of -30 F over the last 20 years (and -58 F for the long-term). I set mine at 45 F for a 24' x 30' x10' (12' roof peak) metal building (not that well insulated) in Texas and with +8 F ambients, it was on 45 minutes/off 15. I did buy 2 but only put 1 in service, as that was acceptable to me. Also, there are recommended minimum clearances of 34" top and 68" below for these units; a 10' ceiling and a 12" unit height means you're almost at minimums (34" + 12" + 68" = 114" = 9'-6") to start. With the radiant heat flux off these units, the area directly below (or directly facing if you mount the unit at an angle, as I did) will get hot, so depending on what you're using the space for, there may be issues with localized 'hot spots'. Having a method to keep the air in the building/room well-distributed is also important (I used 2 ceiling fans) for several reason. The unit will consume O2 out of the air - about 1 cubic foot of O2 per minute. There is a recommended fresh air flow in of 160 CFM for this heater (high, IMO as a Chemical Engineer, but I'd want at least 50 CFM), so proper ventilation is also a concern if your room/building is 'tight'. You can better evaluate your specific application, but I believe one 40,000 BTU/Hr unit would be marginal in that size building (unless very well insulated) in the climate I think you're looking at.

This fan moves air, however I use it at close range in my bed room just a few feet away from bed, accompanied with our air conditioner. I don't see it reaching 150 ft, you may want to try a bigger fan, something made for industrial use.

I purchased this fan for my office at work to help bridge the ten degree difference in temperature from my start time and when work actually turns on the AC which is sometime around 10AM. With the fan pointed at me about 3 feet away and on its lowest setting, it is almost too much airflow. If you have a small office cube this might be too much fan. The amount of air this fan can move would likely make it a great option for non-air conditioned work environments. For the price you can't go wrong purchasing it.

Watch out for a defective fan motor that changes speed by itself. You won't feel any air movement at all. If you are lucky enough to get one where the motor is OK, it does a pretty good job moving air up to about 20 feet.

It's mounted 7'-10' high to be detected maximum distance up to 60'-70' (@75F or less). if just detects 10'-20' away that have to adjust sensitivity knob via clockwise to increase its sensing range.

This isn't going to help you much. Before I did my installation, I called Honeywell and asked this question. The young lady representing Honeywell gave me an answer that wasn't in feet - it was in either square feet or cubic feet (can't remember which but I'm thinking it was cubic feet). I pointed out to the representative that the units weren't correct for a distance but she couldn't provide any other information. I think the farthest distance I've had the wireless thermostat from the EIM is about 40 feet [that distance went through a floor and a wall).

It has different levels of heat range you can set. You need to experiment to see what degree you want. We just usually run it on high (most efficient) until our thermometer reads what we want, then shut it off. Cost less than our heat pump forced air unit to run.

I measured it as 10 degrees in all directions from straight. I hope that helps.

do you have a ceiling in the garage and if so how tall is it, maybe all the heat is going up. can you feel the heat coming out of the heater. I installed it in a 20+20 office and it will run you out in about 15 minutes. hope this helps. Steve

Its meant for contoling a living space. Not sure its intended for non livinbg space (eg 140F). The documentration claims a 1 degree differential. Wrong! My observation is more like 3-4'C ( about 10'F)

I live in Hawaii and my home is about 10 feet above sea level I could pull 28.0"- 28.5 +" hg. I ran the pump for one hour, 29.921" Hg is (absolute vacuum) so this pump is not that far off from absolute. Keep in mind atmospheric pressure and 'your' altitude affects vacuum pump performance

Hi Stony - I am with BAFX Products Support. How far away you can use the thermometer from the object you are temping is really completely dependent on what object you are temping, how big the object is, ambient temp compared to the object being measured and how accurate you are trying to be. Obviously the closer you can be to the object the more accurate it will be in most cases. What I can say for certain is that unless you are measuring a very large object with a high temperature it likely is not going to give very good readings at 20', not many IR thermometers will. To better assist you in your decision making process it may be helpful to know that the D:S ratio on this thermometer is 12:1. This means that at a distance of 12 inches from the object you are temping the thermometer will be taking a reading from the area of about a 1 inch circle. At 36" you will be reading the area of a 24" circle etc etc etc. The further you move away from the object the less accurate it will become. At the 20' you mentioned you would be temping an area of about 20" or almost 2 feet big, plus in this case you will likely then run into the issue of IR heat from other objects you do not intend to measure interfering with the reading as well. I hope this information helps some. If we can be of further assistance please contact us directly through the Amazon messaging system for a faster response as we are not always able to see responses that are posted in this Q&A area in a timely manner. Sincerely, BAFX Products Support

the unit has a heat source so it doesn't seem to matter the temp of the room (above freezing). I have it in my garage and it is often in the 40 degree range. The unit does put out heat when operating (when removing humidity--if humidity is at or lower than your setting the heat turns off but fan continues to operate). You should be fine. I love this thing. I moved from Eastern WA where humidity is hardly ever above 50%, to Western Wa where it is in the 80-99% most of the time. I am allergic to mildew/molds etc and this unit keeps my home dry and no musty scents. I was prepared to purchase a second one for the upstairs but this dandy unit keeps both floors perfect.
