Humidity module

Hygroscopic materials always try to form a moisture equilibrium with the surrounding air. This principle is used to measure the moisture in material by measuring moisture equilibrium.

• Slim design (Ø 4 mm) with remote electronics

Ideal for tight measuring points, based on the moisture equilibrium measured, testo 635 automatically shows material moisture in % in the display.

Material moisture calculation is available for the following materials:
–Concrete
– High-insulation bricks
– Solid bricks
– Hard wood
– Soft wood
– Gas concrete
– Particle board
– Calcium sulphate floating screed
– Cement floating screed
– Lime sand brick
Materials are easy to select from the menu. Using the 'Material' user profile, the material can be accessed directly at the touch at a button.
Additional material characteristics can be stored in testo 635-2 using ComSoft.

Delivery information: Supplied with thin humidity probe (Ø 4 mm) with PTFE protective cap and adhesive modelling clay (four items), including fixed cable.
