TS1 Smart Tensiometer

Eliminates Routine Maintenance

If your task is soil water monitoring you know the problem: water vaporizes and is lost. If soil gets dryer than about 85 kPa, no tensiometer is able to take measurements. Still, as only little water movements occur in extreme dry soils, losing readings is tolerable. Then, when the soil gets wet again, the Tensiometer could actually restart measurements - but first it needs to be refilled again.

Automatic Refilling, Deaeration

Now, the TS1 solves this problem. When the cup needs to be refilled and soil water is available the internal pump will draw water from the soil, refill the cup and remove all air through an exhaust outlet - all automatically. The cup is deaerated automatically, even if only a bubble is detected.

Automatic Emptying

If the temperature probe indicates emerging frost, the TS1 empties itself to prevent damages caused by freezing.
