Features:

• 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)

• 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

• Automatic calculation of differential

Temperature (IR - DP) to determine
condensation point

• Min/Max and Data Hold

• Auto power off and low battery indication

• Complete with pin moisture probe with

cable, 9V battery and case

8-in-1 Meter with Patented Built-in IR Thermometer

Monitor moisture in wood and other building materials with virtually no surface damage with the Pinless

Moisture sensor (Pin-type Moisture Probe included). Measure Humidity and Air Temperature with built-in

probe plus non-contact InfraRed Temperature with patented IR design.
