Product purpose:

The portable soil three parameter measuring instrument TDR 350 uses reliable time-domain reflection technology to accurately measure the change of soil three parameters in a full range.

Through the new function improvement, it can provide accurate measurement and more stable performance for the optimized turf. Capable of measuring soil EC and correcting soil moisture readings. One click to obtain the full soil reading, and a variety of probe lengths can enable you to better measure the data of the target area. Probes are available in 4 types: 3.8 cm, 7.5 cm, 12 cm and 20 cm.
