Protecting the measuring site

4.3 Cleaning

Clean ceramic and sensor body only with a moist towel. If the
ceramic is clogged it may be flushed it with Rehalon®.
If the pores are clogged with clay particles saturate the ceramic and
then polish the ceramic surface with a wetted, waterproof sandpaper
(grain size 150...240).

4.4 Storage

If the T5/T5x should not be used for a year or more then empty shaft
and sensor body to avoid algae growth. Store both in a dry place.
5 Protecting the measuring site

5.1 Theft and vandalism

The site should be protected against theft and vandalism as well as
against any farming or field work. Therefore, the site should be
fenced and signposts could give information about the purpose of the
site.

5.2 Cable protection

Outdoors cables should be protected against rodents with plastic
protection tubes. UMS offers dividable protection tubes as
accessory.
In the lab the cables should be fixed so they are not accidentally
pulled away and that there is no risk of stumbling.

5.3 Frost

Tensiometers are filled with water and are endangered by frost. T5
and T5x should only be use in frost-free surroundings.
Do not store filled Tensiometer at temperatures below 0°C. Do not
leave filled Tensiometers over night in your car, in a measuring
hut, etc.
Do not fill the Tensiometers with Ethanol, as this is corrosive for
some materials (i. e. PMMA) and will destroy these.
