Extech Instruments Big Digit Humidity Alert with Limited Nist
Ideal for monitoring environmental conditions in laboratories, storage areas, manufacturing assembly areas and other controlled environments, the Extech Humidity Alert Meter emits visual and audible warnings when humidity levels exceed high or low limits. The meter features a remote probe that can extend on an 18 inch cable so the user can take measurements behind walls, in ducts, or other areas that are difficult to access.
Unlike other humidity indicators the 445815 calculates and displays the Dew Point reading which is a calculation of temperature and humidity used to determine when condensation will occur. The 445815 also features a large digit LCD screen, which allows for the simultaneous display of humidity, temperature and dew point.

A solid, highly responsive unit
This was extremely accurate out of the box. The temperature was accurate to .1 degree, with reference to a high end Netatmo unit. The humidity was off by 4%, which is within the mfg. specs. I was able to calibrate it to 100% accuracy using a Boveda One Step Kit.The surprising thing is how responsive this thing is. Just getting near it will change the readings, virtually instantly, no lag time. I think the fact this has an exterior sensor makes it far more responsive than one which is built into the unit, which many are.A note on the picture. It looks much larger than it is, which is 4.25"x4", I wanted to show detail so I got in close.
