Features

• Integrated Bluetooth

to transmit readings for remote viewing

• Works with free Android App to display large,

easy-to-read values for: Moisture, Humidity,

Temperature, Grains Per Pound (GPP)/(g/kg),

Dew Point, Vapor Pressure, and condensation point,

up to 30’ (10m) away

• Quickly indicates the moisture content of multiple

wood types and other building materials with Pinless

technology without damaging the surface; Remote

Pin-type probe allows for contact moisture readings

• Manually store/recall up to 20 labeled readings or

datalog up to 50K readings using the Android app

• Easy to read, large dual display with automatic

backlight feature and Fast Analog Bargraph

• Pinless moisture measurement depth to 0.75" (19mm)

below the surface

• Programmable high/low Moisture/Humidity alarms

• Designed with an IR circuit to measure non-contact

surface temperature

®

connects with Android devices

• Automatic calculation of differential Temperature

(IR - DP) to determine condensation point

• Min/Max, Data Hold, and Auto power off

• Complete with pin moisture probe (MO290-P) with

3ft/0.9m cable, 9V battery and pouch case

See back page for meter specifications

Measure moisture of wall material with non-invasive Pinless technology or
use the pin moisture probe for making contact moisture measurements.
Built-in IR thermometer design locates cold spots on walls, which identifies
surfaces subject to condensation.
