Accuracy has never been this easy

At METER, we know tensiometers. We've sold over 20,000 across the span of a quarter century, so if you need a precise, easy-to-use, reliable field tensiometer with outstanding year-round performance, you can rely on the TEROS 32.

Spend more time on what matters

We think you should spend less time fussing with complex installations, and more time on your research. That's why unlike most tensiometers, the TEROS 32 field tensiometer is now plug and play. Just insert the stereo plug into the ZL6 data logger, and start seeing numbers. The TEROS 32 connects to the ZENTRA Cloud system, where all data are connected and delivered through the cloud. Pull up your data instantly wherever you are, and you'll know exactly when it's time to refill, before trekking out to the field.

Faster field visits

To save you even more time and effort, we've outfitted the TEROS 32 with an external refilling tube. No more pulling the tensiometer out of the ground. When it's time to refill, the TEROS 32 can be filled externally without ever having to remove it, saving you hours of tedious maintenance. On top of all that, the tensiometer is highly responsive. It reacts much faster to changing soil conditions than lower-quality tensiometers, enabling you to measure even the most minute changes in soil water potential. Plus, it measures both positive and negative pore pressure.

Now, sit back, and relax

TEROS 32 is a simple, plug-and-play tensiometer that combines METER's legendary German precision engineering with the power of ZENTRA Cloud, giving you easier, faster, more accurate water potential data in near-real time. Just install it and plug it in. It's that easy. With ZENTRA Cloud software, you can review data as it happens from the comfort of your office, ensuring every tensiometer is working as expected. No more worrying if your tensiometer has cavitated. Combine the TEROS 32 with the TEROS 12, and you'll know the best time to go out and refill. Plus, you can use both sensors to generate in situ moisture release curves.

More robust, if that's even possible

Over thirty years of tensiometer experience and fanatical attention to detail have made METER tensiometers extra rugged, but the TEROS 32 tensiometer is more robust than ever before. Technological advancements have made it possible to incorporate a more ruggedized, highly precise pressure transducer, giving you higher data resolution in an almost unbreakable form, and making the TEROS 32 more affordable than its predecessors. Plus, the ceramic and shaft are engineered to be virtually indestructible when it comes to harsh weather (10-year warranty on the ceramic), which means the TEROS 32 is a tensiometer you can rely on year after year in every season.
