Well known throughout NZ, the Surveymaster is a dual function non invasive PLUS probe moisture meter.

It is ideal for locating and measuring moisture problems in homes and building materials such as timber/wood, gib board etc.

Simply hold the meter against the wall and the unit will scan (using the capacitance method), typically up to 19mm from the surface. Where moisture is located, the readings from the meter, which are displayed as digits on the LCD, increase significantly. (Note: Metal also increases the readings of capacitance meters).
The latest model now features a unique "reference mode" for non invasive measuring. The meter can be benchmarked to a known point on a wall, and any changes in measurement will appear as higher or lower in digits compared to this area.

The Surveymaster also features a green, amber and red LED light scale which provides the user with a DRY (green), RISK (amber) and WET (red) visual indicator of moisture levels.

Once an area has been determined as being possibly wet because of high readings, switch the mode on the Surveymaster to the pin/probe mode (WME), and measure the % of moisture.

For deeper readings, the Surveymaster comes standard with a pair of deep wall probes, which can be plugged into the side of the unit.

This unit is ideal for locating and measuring moisture in walls of homes, buildings and apartments etc.
