Extech Instruments MO290, MO290-NISTL, MO290-P Data Sheet

Pinless Moisture Psychrometers + IR Thermometer

8-in-1 Meter with 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 design.

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 an 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

Measure moisture of wall
material with non-invasive
Pinless technology

Pin Moisture Probe included for
making contact moisture
measurements

Patented IR thermometer design
locates cold spots on walls, which
identifies surfaces subject to
condensation (direct differential
display of IR - DP)
