Soil Test Direct Soil Conductivity and Temperature Tester
- Automatic Temperature Compensation
- Penetration probe
- Lightweight and portable
HI 98331 is a special pocket tester designed to directly measure soil conductivity and temperature. With a temperature sensor incorporated into the penetration probe, readings are automatically temperature compensated. Conductivity range can be calibrated in an aqueous solution with a single calibration point.
HI 98331 (Soil Test) is supplied with HI 73331 penetration conductivity probe, (4) 1.5V batteries, calibration screwdriver and instructions.
