1.Introduction
• This is the Pinless Moisture Meter, It is an electronic dampness indicator with a measuring process working on
the principle of high frequency.
• The instrument is used for non-destructively tracing dampness in building materials of all kinds as well as for
detecting damp distribution in walls , ceilings and floors.
• It is particulary suitable for pre-testing the readiness of building materials for covering prior to CM measurement.
2.Features
• Quickly indicate the moisture content of materials
• CM % measured function
• Depth of penetration about 20-40mm
• Measure and HOLD Function
• MAX/MIN display Function
• Alarm Function
• Low battery indication
• Auto Power Off
• White Backlighting LCD Display
