Protimeter MMS Moisture Measurement System Page 3
The following probes and sensors are included in the standard Protimeter 
MMS kits:
• The Hygrostick
®
 (POL4750) and Humistick
®
 (POL7750-2) probes 
measure relative humidity (%RH) and ambient air temperature (T
AIR) in 
rooms or materials. They can be connected to the Protimeter MMS 
instrument either directly or by means of the Hygrostick/Humistick 
extension lead.
• The surface temperature sensor (TS) is used when investigating 
condensation situations.
• The moisture probe is used to obtain percent moisture content values in 
wood or wood moisture equivalent (WME) values in other non-conductive 
materials.
• Deep wall probes are used to obtain WME values deep below the surface in 
solid structures such as walls and floors.
