The standard set
Each SR 1000 type tensiometer tube is delivered ready to use with a Bourdon manometer and a silicone stopper
You also need
. An auger to install the device, ref. STM 21600. . A vaccum syringe, ref. STM 21750 to prepare the tensiometer tubes before placing them. . Anti-algae liquid, ref. STM 21310 to avoid algae developpement.
FAQ
Do the tensiometer tubes need to be prepared ?
As all tensiometers, these tubes have a porous ceramic cup glued on the bottom. Before placing them into the soil, the ceramic must be saturated with gasless water. This can be done with a vacuum syringe, type STM 21750.

COMPLETE TENSIOMETER WITH BOURDON MANOMETER - SR 1000
What do I measure?
The total soil water suction in the tensiometer tube (also known as soil water potential or hydraulic charge)
APPLICATIONS
AGRICULTURE
Precise management of irrigations.
Management of calculated water stress levels for seed production.
AGRONOMY & ENVT
Studies on water bulbs in soils.
Water stress management for modeling.
Checking water potential levels before starting a soil solution sampling campaign.
Following water percolation periods.
HYDROLOGY
Water potential measurements in unsaturated soils.
Soil water caracteristic curves.
Studies on water flows : percolation...
Studies on water ressources : refilling of the water table monitoring.
Water balance.
SOIL PHYSICS
Analysis of water tranfers, water potential measurements.
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. By simultaneously using ceramics with high breakdown values, you will be abble to conduct your experimentation very far without having to refill the tensiometers all the time.

WATER TRAP IN THE MANOMETER
VERY LOW PRICE
TECHNICAL CHARACTERISTICS
Range : 0 to -99 cbar (kPa)
Ceramic : 1 bar standard (optional : high flow, consult us).
Manufacturing materials : seethrough PVC for the tensiometer tube.
Water trap : Entrapment system to keep the liquid in the BOURDON manometer. It considerably lowers the temperature influence on the data given by the manometer.
Operating temperature : +5°C to +70°C.
Storage temperature : when empty, -20°C to +70°C; when full of water, 5°C to +60°C. Use of the silicone bung, SMS type, in order to use the electronic tensimeter SMS 2500S to take more accurate measurements.
