Testo, 0636 2135, Thin Humidity Probe for Material Moisture Equilibrium Measurement

Thin humidity probe with built-in electronics, incl. 4 attachable Teflon protection caps for material moisture equilibrium measurement

Includes

• Thin humidity probe (? 4 mm) with PTFE protective cap and adhesive modelling clay (4 items), including fixed cable.

Materials which take in and retain or release water are described as hygroscopic materials. 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.
Ideally, moisture equilibrium is measured in a bore hole in the material. To keep the bore hole as small as possible, a thin .16 in. humidity probe is used. It should be protected from dirt by a Teflon cap during measurement. The bore hole is then simply sealed using sealing clay.
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

Features

• Measurement of the material moisture via the equilibrium moisture content
• Slim design (? 4 mm) with remote electronics - ideal for tight measuring points
