TDR 350

Soil moisture and conductivity meter TDR 350

The TDR 350 is a measuring instrument for determining the moisture content in soil based on TDR (time domain reflectometry) and the conductivity of the soil. The temperature can also be measured on the ground surface (optional).

This device has an integrated data logger for approx. 50,000 measurements and can optionally be equipped with a GPS module. This allows custom maps to be created that map the geographical coordinates of the soil moisture results. The data can be exported to a USB flash drive, smartphone or tablet. It can also be exported via the optional Bluetooth. The TDR 350 comes delivered with a case.

PET 2000

The PET 2000 activity meter can measure the potential absorption of nutrient salts under the same conditions as the actual nutrient salt absorption through the roots. This means that the dissolved salt content is measured in the soil and... ...more Topseller
