Spillage test on flue gas systems
The change sensor RM400 is used for locating leaks in flue gas pipes.
Before measuring, remove the protective cap from the interchangeable sensor!
Slowly guide the sensor along the points to be tested. If there is a leak, the meas-
ured value changes and the flashing frequency of the red LED in the sensor foot in-
creases with the increase in moisture on the sensor surface.
For measurement, the sensor surface must be dry and at room temperature.
