METER SUPPORTS TAHMO
Trans-African Hydro-Meteorological Observatory (TAHMO) is a not-for-profit organization. TAHMO makes high-quality data freely available to governments, scientists and farmers in real time.
Soil moisture sensing—reinvented
The TEROS 12 goes beyond merely optimizing the reading to optimize the accuracy of the whole data set. It combines consistent, flawless installation, minimal sensor-to-sensor variability, and a large volume of influence to deliver performance, accuracy, and reliability at a price you can afford.
DISCOVER ALL ATMOS INSTRUMENTS
As world experts in soil-plant-atmosphere measurements, we developed the ATMOS weather and climate product line without any moving parts to keep it reliable and simple.
Only using partial curves? Get what you’ve been missing.
Now, generate complete high-resolution moisture release curves across the entire moisture range. It’s easy. Start with the WP4C, then just add HYPROP. Mix in data from the KSAT to add a full hydraulic conductivity curve.
