Extech MO290 Pinless Moisture Psychrometer with built-in Infrared Thermometer
The Extech MO290 combines a pin/pinless moisture meter with a built-in infrared thermometer, allowing you to measure temperature, humidity, dew point, vapor pressure, and much more. Comes complete with pin moisture probe, 9-Volt battery, and case.
8-in-1 Meter with Built-in IR Thermometer
✅ Destructive or non-destructive measurements
Test for moisture using built-in pins or using the sensor, to a depth of 25 mm (~1 in)
✅ Clear, Accurate Readings
The audible alert beeps faster as moisture levels increase; display icons indicate low, medium, or high moisture content
✅ Easy to use
Compact and efficient, with a built-in battery level check and measurement verification test
