This is a reasonable priced and valuable tool for those who want to apply paint and finishes under the ideal conditions or those who do precision HVAC work and want to fine tune the Freon change and blower performance to match the conditions at the time of set up. It is easy to use and the readings of relative humidity, dew point and wet bulb relative humidity are almost instantaneous. It also gives you ambient temperature. It has a shutter on the top that helps protect the sensors when not in use. It is really handy is you need this type of information quickly and easily.

This is a very handy meter that gives me all my readings in one tool, instantly on one screen. It's not just for HVAC or restoration pros, but also DIYers that want to know just how much humidity is in a room, shop, paint booth, AC flow, heater air flow, etc. I use mine to help in the shop when measuring humidity for painting and spraying stains. Too hot or too wet with a high dew pointand I'm out of business for the day so this meter is a great help. It comes with everything you need, just take it out of the box, insert the included battery and get to testing. The meter can display the relative humidity (RH) above the ambient, dew point or wet bulb temperature on a backlit screen. It can measure temperatures from 14-122°F with high accuracy. Relative humidity measurement ranges 0-99.9%. Simply put, this is very very easy to use and works well. I love that all my info is on one screen and I can keep this in a shirt pocket for on the fly measurements. I'd recommend it.

Compared to my dehumidifier’s humidity readout this is quite accurate. The tool is continuously re-sampling the humidity so one sees the readout constantly change, in small increments, when studying the screen for a while. The screen is very easy to see and the powerful back-light comes on automatically when a function button is pressed. The same can be said of the comprehensive instruction manual as well – the larger type is very easy on the eye. The sensor is protected by a cover and that needs to be rotated to open to start using the tool – see video for a quick overview. The supplied nine volt battery provides the power and the auto off function preserves that power, albeit that can be overridden when the twenty minute time limit is too … limiting. A one year warranty is provided.

The General Tools 4-Function Digital Thermo-Hygrometer Psychrometer is useful for the building maintenance person needing to get environmental readings. I manage a building with two chillers and 8 air handlers. Frequent adjustments need to be made, usually when the weather changes, and this device is effective for giving me the temperature, humidity, and wet-bulb numbers I need. I have a small, pocket-size thermometer/hygrometer I've used for about two years. Side by side they were within 0.5 degrees for temperature. The biggest discrepancy was a 6.6% difference for humidity. I wish I had a third device to get a better feel for which was more accurate but my gut was telling me the General Tools was the winner. My biggest gripe, and the reason for only three stars, was a screwdriver was needed to open the battery compartment. I didn't have one available at first so I didn't get to test the device right away. Once I was done playing I removed the battery for storage. I dropped the small, eyeglass size screw twice before I managed to get it reinstalled. Not something I would want to mess with out in the field. My only other complaint is the lack of a carry case, belt clip, or wrist strap. For the price I feel something should have been included.

The 4-Function Digital Thermo-Hygrometer Psychrometer Was shipped in a bigger box to protect it from damage. This is a cool and easy to use unit, it tells you the air temperature humidity dew point wet bulb temperature also has a hold button and min / max functions a easy to read back lit display, 20 min auto shut off, low battery indicator. it can be field calibrated, comes with a 9 volt battery and has a 1 year warranty. the instructions are in English and explain how to use the unit and all of its functions as well as field calibration. Works Great ! the only thing missing is a carry case or wrist strap, with every thing that is included and how well thought out it is. I am surprised they for got to include one of those.
