HYPROP system
Laboratory evaporation method according to WIND/SCHINDLER for
the determination of unsaturated hydraulic conductivity and water
retention characteristics of soil samples.
1.1 Safety instructions and warnings
Electrical installations must comply with the safety and EMC
requirements of the country in which the system is to be used.
Please note that any damages caused by users are not covered by
warranty.
Tensiometers are instruments for measuring the soil water tension,
soil water pressure and soil temperature and are designed for this
purpose only.
Please be aware of the following warnings:
High pressure: The maximum non destructive pressure is
300 kPa = 3 bar = 3000 hPa. Higher pressure, which might occur
for example during insertion in wet clayey soils or during refilling
and reassembling, will damage the pressure transducer!
Ceramic cup: Do not touch the cup with your fingers. Grease,
sweat or soap residues will influence the ceramic's hydrophilic
performance.
Freezing: Tensiometers are filled with water and therefore are
sensitive to freezing! Protect Tensiometers from freezing at any
time. Never leave Tensiometers over night inside a cabin or car
when freezing temperatures might occur!
Do not use a sharp tool for cleaning the threads in the sensor unit.
Just rinse it with pure water from a spray bottle.
