MO290: Pinless Moisture Psychrometer + IR8-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.Includes:Pin moisture probe with cabl9V batteryCaseFeatures: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 materialsEasy to read,large dual display with automatic backlight featureSimultaneously displays moisture value of wood or material being tested,Air Temperature,IR Temperature,or HumidityPinless measurement depth to 0.75" (19mm) below the surfaceProgrammable high/low Moisture and Humidity alarmsDesigned with a patented IR circuit to measure non-contact surface temperature; 8:1 distance to spot ratio with 0.95 fixed emissivityBuilt-in Humidity/Temperature probe measures Relative Humidity,Air Temperature plus Grains Per Pound (GPP)/(g/kg),Dew Point (DP),Vapor Pressure,and condensation pointAutomatic calculation of differential Temperature (IR - DP) to determine condensation pointMin/Max and Data HoldAuto power off and low battery indicationMeasure moisture of wall material with non-invasive Pinless technologyPin Moisture Probe included for making contact moisture measurementsBuilt-in IR thermometer design locates cold spots on walls, which identifies surfaces subject to condensation (direct differential display of IR - DP).
