Hi, what is the % of accuracy for this device and does it measure accurately at less than 40 foot candles?

I have the Model LX1330B. The specifications in the instruction manual reflect the following: Light-measuring level from .1Lux to 200,000Lux Accuracy +- (3%rdg+10dgt) &lt;=20,000Lux/2,000FC +- (5%rdg+10dgt) &gt;= 20,000Lux/2,000FC Repeatability +-2% Photo detector lead length ~150cm Spectral Sensitivity- curve shows mostly betweeen 500nm and 650nm The specifications page does not directly relate to foot candles, but hope this helps.

I can't verify the accuracy except that it matched those of others with whom I've compared mine against. It will read from 0.1 lux to 200,000 lux. I use mine in an Integrated Sphere to measure flashlight output in lumens down to the hundreds of a lumen. It's a great meter!

I have no other device to compare it with so I have no idea of it's accuracy. We use it for comparitive purposes so for that it's useful. The "manual" is very tiny page, with a tiny chart for weighting and frankly I've misplaced it. Other than that, there is little info. However it does seem very well made. I has the feel of a Fluke multimeter.

I have had no problems with mine. Accurate as far as I have been able to determine.

It is supposed to detect 25, but I got a clear (light) line on one and then had a quant of 11 later that day, so they are more sensitive than advertised!

Easley 20 feet plus, I am about 30 feet back from the street, and I have to point the sensor down a little to keep the cars on the street from turning my light on. The manual says 50 feet, and I have no doubt it will detect from 50 feet. To date, I am totally satisfied with this unit, even at -5 degrees F this detector functions perfectly, better than any other motion detector I have ever had. Mine did not come with an ezplate, as I only ordered the sensor.

I don't have the tool with me right now to confirm but I have used it up top 64 feet and its accurate to a 1/16" of an inch.

So far, it gives you the location, but I tend to find that the device is not accurate past 20-30 feet. So if you are using to track a person with some sort of cognitive issue, you will know the general area to look, but not the specific area.

It does not measure. It only gives you a level or plumb line. It's nice because it self levels, you don't have to level it your self. It's probably off 1/16" at 50'. It's best at max of 30' since most people move the laser to a different spot if it's any further. I've gone 50' + setting lights on a 20' ceiling and I could not tell any accuracy issues. It also hooks on to a screw of a metal 4sq box and the laser lines up with the center Knockout. I love this laser. The one I had before was a manual level craftsman. This is a big step up.

I do not know. However it is as accurate as the device in my doctor's office.

No, the meter only reads the real time light intensity in foot candles. You would need multiple readings throughout the day and then estimate an average.

I have used it to measure soil moisture in our lawn, around trees and just about everywhere else. I believe it to be very accurate. I bought it because I found that the soil moisture gauges in the nurseries around here were not accurate. Of course, the accuracy depends on following the directions that come with the meter so assure accuracy. I have found the device to be accurate and useful. I would not give it up.

I mounted this on a shotgun that is for home security, therefore accuracy at more than 25 feet or so isn't needed. It can be adjusted so depending on your application, it may need to be adjusted for height or windage.

This seems to be a very well made tool and is graduated to allow readings down to 0.0001". I am not sure I would trust it to be real accurate to such dimensions. Your touch would have to be better than mine to feel confident to readings less than 0.001. - Chet

I wish I could sincerely answer your question. This device has not been the best so far. Constant calibration and off results. I would suggest investing a little bit more money on a better scale.

Accurate? Probably not. It's manual states that its DC current accuracy is 3% +- 2 digits. But unless you get it calibrated you can't be sure of that.What kind of accuracy do you need? If you're considering this meter, it's probably good enough.

Sorry Scott, I can't. I only know there is no uniform calibrating of meters - and therefore they are all different. After trying 3 - I found, for me, the Freestyle Lite to be the most accurate. My daughter uses One Touch - and her readings come in high too.

I have found mine to be very accurate. Perhaps you did get a defective one and should ask for it to be replaced.

Yes, but like I said in my review the accuracy of the meter leaves a lot to be desired. I tested AA and AAA rechargeable NiCad batteries using the meter and it gave me the same, false, inaccurate meter readings. The meter indicated there was a good "green" full charge, but when I put the batteries in my digital recorder and tv remote the batteries had such a low charge in them they failed to operate the equipment. I bought two of these meters and they both give the same false readings, so either I received two faulty meters or they're just not accurate.
