METER TEROS 12
Our take

Three readings from one soil measurement point.

TEROS 12 is a practical choice for a monitored soil or substrate point where EC is part of the irrigation decision. Its 70 MHz capacitance measurement and epoxy body are paired with stainless steel needles. A ZL6 logger and ZENTRA Cloud provide one route to remote data.

Field fit

Where it fits

Commercial greenhouses, substrate monitoring and field projects with a compatible logger.

Plan the installation

Budget for the logger and telemetry. Install with close soil contact and use a suitable soil or media calibration. The ZSC Bluetooth interface is an accessory.
