The Surveymaster SM
A dual function instrument that combines the proven two-pin inspection
method with a new non-invasive radio frequency technique. The result is...
...a NEW moisture meter for rapid and thorough inspection of buildings
for dampness on and below a surface.
This easy-to-use instrument employs two electronic circuits:
The first is for the conventional two pin method which shows whether
a surface is dry, damp or wet. This is known as the Measure
The second is based on radio frequency emissions with the electronics
located in a 'bulge' at the back of the instrument. It is capable
of measuring moisture through many wall and floor coverings and
ceramic tiles. This is known as the Search mode.
The two-pin measure mode. This shows by means of green, yellow
and red LED's whether a surface is safe ie air-dry, 'borderline'
or damp. The dampness measured is quantified on the LCD display
to one decimal place in terms of % wood-moisture-equivalent (%WME).
The new search mode. This shows by means of the same colour coded
LED display as the measure mode if the fabric of a wall is dry
or damp below a surface. There is also a volume-adjustable audiable
alarm synchronised with the display. In this mode the meter employs
radio frequency emissions (RFE) to measure moisture through most
wall and floor coverings including ceramic tiles.
