Description
The THWD-3 uses a precision capacitance sensor to deliver accurate performance with long term stability. This high accuracy instrument measures the full range of relative humidity from 0% to 100% and features an exceptionally wide ambient temperature measurement range from -4 °F to 140 °F. The sensor is mounted on along shaft extending from the top surface of the unit, making probing into ductwork and hard to reach areas more easy. The large LCD displays two measurements simultaneously with a full range of display options including hold, min, max, dew point (DP) and wet bulb (WB).

Great Product
Very easy to use product that works every time you need it to, We have several of them that we use in teaching our HVAC classes and are very happy with the accuracy and the easy read feature. This tool has passed the ” student abuse” test of everyday operation, they have been dropped, kicked across the shop floor, and left in a walk in freezer, yet they continue to operate as expected.
Great tool for any HVAC technician
✔ Yes, I recommend this product.

More than I expected!
This meter performed even better that I was expecting. Checked readings against a Fluke 971 and it was right on point! Feels nice in hand and the only difference that I see with its bigger brother is the quality of plastic used. Talking about performance, it has been accurate and fast in readings. I totally recommend this meter to anyone in need to get accurate humility measurements.
✔ Yes, I recommend this product.

Solid and accurate temp readings
I happened to win this meter over at HVAC Shoptalk’s swag Tuesday giveaway!!! With being said, it has earned a spot in my veto. I use it for the high/low feature to take temps across my small refrigeration condenser coil. It’s nice to see a differance in determining if the charge has leaked out on units on closed systems. Not needed so much to me, but seeing WB and DP are neat
✔ Yes, I recommend this product.
