Get ready to start a measuring campaign
4.2.2
Introduction
Before starting and after every completed measuring campaign (the
sample is dried out) the Tensiometers need to be filled or refilled
bubble free with deionised and degassed water.
Keep the ceramic moist when not in use by covering them with the
water filled rubber cap.
Ceramic tip: Do not touch the tip with your fingers. Grease, sweat
or soap residues will influence the ceramic's hydrophilic
performance.
The HYPROP-service kit or a vacuum system and a PC/Laptop with
®
tensioVIEW
software are required for filling or refilling.
