Beskrivning

Small, practical and cost-effective: The moisture indicators are made from special absorbent paper, certain parts of which are impregnated with cobalt (II)-chloride solutions of varying concentrations. The colouring from blue to purple to pink shows the change in relative humidity in the ambient air. Depending on the indicator’s design, the colours can change in reverse sequence once the air humidity decreases (reversible indicators).

At a test temperature of 20°C (+/– 2°C), the permitted tolerance is +/– 5% relative humidity.
The deviations are approximately 2.5% relative humidity per 5°C above and below 20°C.

The indicators are reverseable and have three languages on them, English, German and French.
