Extech MO300 Moisture Meter with Bluetooth

The Extech MO300 Moisture Meter with Bluetooth measures moisture levels in air, wood, and building materials using both pinless and pin-type technology. Thanks to its MeterLink Bluetooth capabilities, it can also wirelesly transmit moisture and humidity data to certain FLIR thermal cameras, including all Exx-Series and T-Series cameras.

The MO300 pinless function measures to a depth of 0.75 in (19 mm) to detect moisture in and under materials including wood, concrete, carpet, and tile. The included pin-type probe includes a 3 ft cable and is great for checking moisture in rough lumber, subfloors, and siding. The MO300 can also measure surface temperature through the built in infrared thermometer with an 8:1 distance-to-spot ratio. The humidity and temperature probe on top of the meter measures relative humidity and air temperature, and allows the MO300 to calculate dew point, vapor pressure, and plus grains per pound (in GPP or g/kg). A unique Condensation Mode uses data about temperature and humidity to warn you when objects may be at risk of condensation. While scanning walls or other surfaces with the infrared thermometer, an alarm will sound to indicate temperatures found to be at or near the dew point.

Twenty labeled readings can be stored manually and programmable high and low moisture and humidity alarms can be set by the user. The large, backit screen simultaneously displays the moisture value of wood or building material being tested, air temperature, IR temperature, or humidity. Other features of the Extech MO300 Moisutre Meter include an automatically-displayed analog bargraph, record/recall of minimum and maximum measurements, data hold, auto power off, and low battery indication.

  • Quickly indicates the moisture content of materials with Pinless technology without damaging the surface
