Extech MO297
Pinless Moisture Psychrometer
with IR Thermometer and Bluetooth MeterLink

  • Quickly indicates the moisture content of materials with Pinless technology without damaging the surface
  • Remote Pin-type probe (MO290-P included) allows for contact moisture readings (3ft/0.9m cable length)
  • Manually store/recall up to 20 labeled readings
  • Works on multiple wood types and other building materials
  • Easy to read, large dual display with automatic backlight feature
  • Simultaneously displays moisture value of wood or material being tested, Air Temperature, IR Temperature, or Humidity
  • Pinless measurement depth to 0.75" (19mm) below the surface
  • Programmable high/low Moisture and Humidity alarms
  • Designed with a patented IR circuit to measure non-contact surface temperature; 8:1 distance to spot ratio with 0.95 fixed emissivity
  • Built-in Humidity/Temperature probe measures Relative Humidity, Air Temperature plus Grains Per Pound (GPP)/(g/kg), Dew Point (DP), Vapor Pressure, and condensation point
  • Fast Analog Bargraph, Min/Max and Data Hold, Auto power off and low battery indication
  • MeterLink™ Bluetooth transmitter wirelessly transmits moisture and humidity data to selected FLIR thermal imaging IR cameras to incorporate meter readings with thermal images
