My unit arrived out of calibration for temperature. It was off at least 10 degrees F. The company then told me I would have to spend over $108 to get 2 salt units to calibrate this unit. I returned it.

Works as advertised. Measured with other devices this one is very accurate. Will be a great portable/mobile psychrometer. I like the ability to change modes.

Works well, not the best but good. Bought this for an employee and he seems to find it a good tool.

This tool works great. Shipping was quick, price was very reasonable. I do HVAC work and currently use this tool. Better than a sling psycrometer.

I bought this instrument to calibrate my new Davis weather station. I also bought the 33% and the 75% humidity calibration kits from Ambient Weather.I'm very happy with the EP8706. It reads to one-tenth of a percent humidity and one-tenth of a degree Fahrenheit and has nearly instantaneous response time for both humidity and temperature.Humidity calibration of the EP8706 is simple, but the cal kits must be purchased separately. The Ambient Weather cal kits that I bought include a transparent zip-top bag for each cal point that's large enough to put the EP8706 inside and seal it up. The button-presses needed to carry out the cal cycle are easily done right through the zip-top bag. Several vendors offer small "pill-box" calibrators, but I wasn't sure the EP8760's probe would fit the small hole in the "pill-box" properly, so I went with the zip-top bag type. Once you place the instrument inside the bag and seal it closed you can move it around and handle it without being concerned about compromising the cal cycle.No temp calibration is available on the EP8706, but when it's compared to an NIST-traceable lab-quality Omega HH21 thermocouple thermometer they agree within two-tenths of a degree.My new Davis weather station was within Davis' tech specs when it was shipped, and now I'm confident that it's humidity and temperature data is as accurate as it can possibly be.Ed

the humidity is consistently off. but better than nothing. I would estimate that it is off by 5 points of relative humidity. for an accurate psychrometer you will pay a lot more.
