Tensiometers are by far the most accurate, precise and highest resolution instruments for measuring soil water potential in the wet end. UMS's line of tensiometers are engineered and produced with extreme tolerances, giving them the best performance characteristics of any tensiometers ever made.
Traditional tensiometers cavitate around -80 kPa. Fanatical attention to detail in design and manufacturing (along with a few mystical tricks of physics) have enabled UMS to build tensiometers that can go beyond -200 kPa.
The cutting edge of the auger has a tapered tip similar to the shape of a Tensiometer or pore water sampler. Thus, the bore hole is large enough to insert the shaft, but the cup will have a tight and perfect fit to the soil.
The not recommendable slurrying of the cup with quartz clay can be avoided.
A divisible auger set includes:
|Cutting Edge||22 mm dia. x 50 cm||26 mm dia. x 50 cm|
|Tip||20 mm dia. x 5.6 cm
||24 mm dia. x 5.6 cm|
|Total length||1.25 m
|for shafts with||20 mm dia.||24 mm dia.|
|Extension rod Part no.||TBE-100|

Lab refill kit for tensiometers (includes T4 and T8), includes stand with clamps, adapter that fits sensor body, 500 mL bottle, pressure gauge, tubes, beaker, and refilling syringe.
Refill kit for external refillable tensiometers (includes T4e and T8), includes hand-operated vacuum pump, 500 mL bottle, refill syringe, tubes and valves.t
The T5 Refill kit & tool set includes refill equipment needed to properly refill your T5 tensiometer. It also inlcudes an Auger kit and connecting cable for Campbell Scientific Dataloggers.
The tensioLINK USB converter is used for directly connecting sensors and devices with serial tensioLINK to a PC. One can configure features and read out measured data.
UMS devices with 8pin M12 connectors (e.g. TS1 or T8 tensiometers) could be directly connected to the converter without the need for a further power supply. The sensor is powered through the USB interface.
Use with the PC-Software tensioVIEW. Manual Software and Driver come along with supplied CD.
