beam to strike the eye from a reflective surface 

 

Do not use the laser near explosive gases or in other 
potentially explosive areas 

Features 

 

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

 

Optional remote Pin-type probe (MO290-P) allows for moisture readings at different 
penetration levels (3ft/0.9m cable length);

distance to spot ratio with 0.95 fixed emissivity 

 

Built-in Humidity/Temperature probe measures Relative Humidity, 

 

Air Temperature plus Grains Per Pound (GPP) and Dew Point (DP) 

 

Automatic calculation of differential Temperature (IR - DP) 

 

Min/Max and Data Hold 

 

Auto power off and low battery indication
