SONDES
PIEZOMETRIQUES MANUELLES OU A INTERFACE
Les mesures de niveaux d’eau constituent la base de toute étude
hydrologique (porosité du sol, déter-mination de la direction
du courant de nappes souterraines, etc.). Il existe de nombreux systèmes
pour mesurer les hauteurs d'eau dans des forages, piézomètres,
puits, eaux libres, réservoirs ou autres.

5 CHANNEL TENSIOMETER SET WITH MERCURY MANOMETER - STM 2150
Known as the original method to measure water potentials in soils, the
tensiometer has become an easy to use and very handy tool for field research
in agronomy & agriculture. The STM 2150 is based on the mercury manometer
principle and is at the same time very cheap and robust. This measuring
principle, easy to set as well as very precise, will certainly bring
you much help in the laboratory as much as in the field. Its life time
is very
long and it doesn't need much upkeep work. By simultaneously using tensiometer
tubes which breakdown values are very high, you will be abble to conduct
your far away experimentations without having to refill the tensiometers
all the time. To sum up, a simple manual equipment, very accurate, inexpensive
and very robust.
COMPLETE TENSIOMETER WITH BOURDON MANOMETER - SR 1000
Accepted as the way to measure the water potential in soils, the tensiometer
has become an easy to use and very handy tool for field research (agronomy)
and managing inputs in agriculture (water). The SR 1000 tensiometer is
robust as well as cost effective. Measurements are taken with a BOURDON
type manometer. This measuring principle, easy to use as well as very precise,
will certainly bring you much help in the laboratory as much as in the
field. Its life time is very long and it doesn't need much upkeep work.
HAND HELD PRESSURE SENSOR FOR SMS TENSIOMETERS - SMS 2500S
The measuring technique with the SMS 2500S electronic pressure meter consists
in piercing through a silicon bung closing a tensiometer, by means of a
hypodermic needle, itself connected to a pressure transducer (or vacuumeter).
This type of measure, both very precise and very economical (a unique appliance
can be used on a great number of tensiometers) is particularly practical
for all users of tensiometric technics in general. This appliance is easily
transportable in its small bag and will allow the user to envisage all
field experimentations more or less far from the laboratory. It is obvious
to use such a system in agronomy or agriculture for managing water use
: determination of irrigation conditions, of the amount of water needed
and of the best moment to irrigate.
SIMPLE TENSIOMETER TUBE - SMS 2000
The SMS series tensiometric tubes are designed to be used with the electronic
hand held meter, ref. SMS 2500S. SDEC France's tensiometer tubes are also
compatible with all other tensimeters on the market (compatible outer diameter).
