Reading high radio/microwave EMF near Hydrofarm thermostat, any comments? I got my Trifield meter a couple weeks ago. One device I was surprised emits a LOT of radio/microwave EMF is the Hydrofarm thermostat ASIN B000NZZG3S. Even six inches away from this thermostat will absolutely peg the meter. And it seems to be 'pulsed' like when reading near a cell phone that's in a call. I don't get readings like this even near computing equipment. Just trying to figure out what these Hydrofarm thermostats emit so much EMF. Thanks! Reading high radio/microwave EMF near Hydrofarm thermostat, any comments?

Yes is normal because of the spark generated from the thermostat.........it is difficult in this time to be "clear " of EMF...have a good time Alexis

No idea, I never owned such thermostat, just noticed that the Infrared Sauna we had, emmits hube amt of EMF, THEN AN OLDER MODEL WITH CERAMIC HEATER DIDNTDEPENDS ON CHEAP MANUFACURER

Is the Hydrofarm thermostat some kind of "smart" thermostat? (One that controls select areas of your house)? These smart devices are constantly sending signals to the areas they monitor and thus will be much higher in EMF's. Either way, I would probably swap it out for a standard thermostat - especially if it is on a wall (or behind) a wall where you sleep or spend a lot of time.

Did you check with where you got the Hydrofarm thermostat as to why this is happening? My first thought is this works off of some type of radio/microwave. Might want to check with the installer of the device to see if they have any information.

Thanks Peter;I'm interested in your approach - but can't follow your text description. Could you provide a 'diagram'???I also have EE background - would like to try metering my clothes dryer(220VAC).BTW - do you have a recommendation for a 'whole house' WAM?? preferably with logging, USB capabilityRegards,WT

Hi Shane,as you know these meters are very sensible. Off 2 Amps looks like mech. damage. When you move the meter the needle should move free in either direction. There is a black plastic screw below the gage. Here you may adjust the needle, but not sure whether such a large misalingement of 2 Amps. Does the Ampmeter works anyway????Good luck my friend

Hi-This manometer guage was installed this outside on a 1.5 inch pipe supplying air into my hi-efficiency boiler.I wanted to determine pressure variances at three locations along the pipe to understand pressure loss at points along the pipe.The manometers were also installed along the 1.5 inch exhaust pipe, too.The manometer was outside here in Colorado when the temperature dropped to an indicated 22 degrees.It was attached into the 1.5 pipe at four inches outside away from the house wall.Perhaps it was only at 24 or 25 degress due to its closeness to the thermal mass of the house.The manometer did not freezeThe tube is a plastic material so would have some give or flex if frozen.Thanks Hi-This manometer guage was installed this outside on a 1.5 inch pipe supplying air into my hi-efficiency boiler.I wanted to determine pressure variances at three locations along the pipe to understand pressure loss at points along the pipe.The manometers were also installed along the 1.5 inch exhaust pipe, too.The manometer was outside here in Colorado when the temperature dropped to an indicated 22 degrees.It was attached into the 1.5 pipe at four inches outside away from the house wall.Perhaps it was only at 24 or 25 degress due to its closeness to the... » Read More Hi-This manometer guage was installed this outside on a 1.5 inch pipe supplying air into my hi-efficiency boiler.I wanted to determine pressure variances at three locations along the pipe to understand pressure loss at points along the pipe.The manometers were also installed along the 1.5 inch exhaust pipe, too.The manometer was outside here in Colorado when the temperature dropped to an indicated 22 degrees.It was attached into the 1.5 pipe at four inches outside away from the house wall.Perhaps it was only at 24 or 25 degress due to its closeness to the thermal mass of the house.The manometer did not freezeThe tube is a plastic material so would have some give or flex if frozen.Thanks « Show Less

No issues @ hi power. Perhaps low voltage at the radio (not the power supply - I check my voltage at the radio, not the power supply as there can be voltage drop at the radio end.). If your using a power supply, check/adjust voltage - also be sure the power supply can handle the power.Have you checked your SWR's? If its to high, you get power feedback to the radio, not good. Heating issues? be sure the radio isn't overheating, the fan should be working when transmitting, to a little after key off, or thermal signal calling for the fan.Check Yaesu FAQ's (if they have that) and/or contact who you purchased the radio from, maybe Yaesu if need be.

No it doesn't. Try an EMF Trifield Meter - that'll work. Here's the one I have and it seems to work great :Trifield 100XE EMF Meter

How far away is the antenna farm for that station? If it is over 30 miles away that might be the issue. You may also want to see if there is anything that is very high that may be between you and the antenna farm. If that is the case, you might be able to just raise the antenna higher.

I read about 3 milligauss with the meter right against the cable connection at home with Comcast cable. I read off the charts from the electrical receptacle which is about 1 foot away from it though. Maybe your reading something else at the same time?

Interesting Question - that's why I bought the one I have. I was very surprised at the results. I have stood under high tension transmission lines and utility poles with a transformer and they are high enough to pose little problem. Some of the highest reading I encountered was the motor on my high efficiency water heater motor, computer scanner and printer power supplies, a bedroom alarm clock - but you virtually have to be hugging them - if you are a foot or two away, the levels are not dangerous. I believe getting a good unit is worthwhile, just to prove what is safe to yourself. I haven't encountered anything dangerous in my normal surroundings and activities and feel safe. Not to say there is nothing out there - need to avoid MRI, etc. Measure at a source and then a foot or so away. Good Luck - I encourage you to get one - you'll feel better knowing. Ron

I'm pretty sure it's "hot", the trigger just causes the wire to feed. I don't see why that would be a big deal. Turn the thing off when not in immediate use. Probably some regulatory goon, industry or union person looking for an "issue" to limit competition.

It has been my experience with these units, (I have 4 In/Out temp units) that it is best to run them thru the firewall to a point in front of the radiator. (bout 6 inches away from the radiator itself. This allows air to flow across the sensor when you are moving thus giving a realistic outside temp. Of course the temp reading goes up when you are sitting still, but it's still good. The next best option is to run the sensor wire along the dash and down the door post and into the cavity in front of the door. This gives a reasonable temperature indication, but will be erroneous when the vehicle is sitting in the sun, and will not respond a fast as it would in front of the Radiator. Good luck.

I tested it against other emfmeters.No documentation is available. I suppose it measures V/m for low frequencies waves, not. radiofrequencies.It worths price se paid!

no, this EMF sensor is not designed for that purpose, it will show only the magnetic field around a cell phone, but cell phone radiation can not be displayedregards

Yes, it measures EMF from anything. If I set the meter to EMF and then put it down next to my cell phone (an Android), I see the meter increase as the meter gets closer to the phone. I also see the meter spike off the chart from time to time as the phone emits bursts of power for this and that. That's true for most anything that uses electricity, including other screen-based devices (monitors, etc.). The contradicting answers that you are seeing are probably because there are different types of waves to measure and different phones have different emissions; this device measures micro/radio waves and EMF. This device did measure micro/radio waves for my phone when I tried it, but I don't know if it's measuring the full emissions of the phone because the level registered when I did a test was very small (I put the meter down next to my phone and dialed another phone and stayed connected for a while). However, I haven't seen any consensus among scientific studies that those types of cell emissions are dangerous, whereas-though there is still some debate-some studies agree that high levels of EMF (around or above 4 milligauss/.4 microteslas) increase the risk of certain childhood cancers.

Yes, this devive measures Electro-magnetic fields as well as radio frequencies. Your microwave transmitts radio fequency. Your other devices transmit electro magnetic fields . Basically the closer you are to the device in question the higher the readings. So the farther away you are the safer it is. I like the meter and would recomend it for shure. It also has electric field measurement. Up to 3 mili gaus is considered safe.

Bryan I just checked the instructions for my meter and it refers to using "special K type thermocouples" to actually touch something to get temperature, but I cannot remember if my meter came with any. That does not mean it didn't, I may have misplaced them. This function was not a big concern of mine so I never used it. The meter does read ambient temp just by putting it on the setting. Also be aware that the reading in Celsius, not F, if that is a concern you will obviously need to convert, however, not really a big deal. Hope this helps. Mike

You might want to check with the seller. I have the EMF Shield but I have never measured changes in EMF levels. If you do get the EMF Shield and measure, I would be interested in seeing what your results were like!
