GANN HYDROMETTE COMPACT B

General Information

The Hydromette COMPACT B is an electronic dampness indicator with a patented measuring process
working on the principle of high frequency measurement.
The device 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.
The device is particularly suitable for pre-testing the readiness of building materials for covering prior
to CM measurement.
Measuring Range:
0 – 100 digits
The magnitude of the value measured is mainly determined by the raw density and the water content
of the material. The depth of penetration of the measuring field, depending on raw density, is ca. 20 –
40 mm.
Adjustment
The device is calibrated fully electronically and readjustment is not necessary.
Battery
Transistor block battery 9V. Type IEC 6 F 22 or IEC 6 LF 22.

Changing the Battery

The battery requires changing when two decimal points are shown in the display (e.g. 1.8.8). Loosen
the two cross-headed screws on the upper side of the device and carefully remove the cover in an
upward direction. Change the battery and refit the cover.
Safety Advice
There is a danger of injury if the metal ball comes into contact with live parts. Do not use the device in
the immediate vicinity of older equipment or equipment equally sensitive to high frequencies (e.g.
functioning medicinal devices). Use the device only for measuring the dampness in hardened building
materials by bringing the ball into contact with the surface.
Check
Hold the device as near to the lower part of the housing, opposite to the ball sensor, as possible.
Press the start button and hold the device with the ball in the air. The displayed value must vary
between –5 and +5.
Operation
Hold the device as near to the lower part of the housing, opposite to the ball sensor, as possible.
Press the start button and use the ball to scan the surface under investigation. The ball must be in
firm contact with the material. To obtain the best results, the device should be held at an angle of 90°
to the surface to be measured.
