Precise as a laboratory and as mobile as a cell phone.

This TDR device measuring the soil moisture content, the soil conductivity EC, and the level of salt contamination can now be performed as fast and easy as never before! Within two seconds, the moisture content value, the temperature, and the soil conductivity EC are displayed on its clear display.

The probes will report soil EC as standard simultaneously with soil moisture content percentage.
The probes measures conductivity with the same large soil volume as it will be used for the TDR moisture measurement.
It’s durable and waterproof construction ensures safe handling even under difficult environmental conditions.
