Professional Pocket Soil Meter

The HI-98331 Professional Pocket Soil Meter (Direct Soil Conductivity and Temperature Test) is used by professionals placing it directly into the soil to test for nutrient or fertilizer levels, the HI-98331 takes the guesswork out of feeding and tending during key growing periods.

This special pocket tester is 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.

Main benefits:

• Robust yet lightweight and portable construction
• Temperature sensor contained within the penetration probe
• Conductivity range can be calibrated in aqueus solution with single calibration
• Allows you to check the EC of each plant from inside the growing medium
• Check plants individually for greater control
• Prevent salt build up inside the pots
• Prevent underfeeding
• Probe has built in temperature sensor, EC readings are automatically temperature compensated
• Also gives temperature reading from inside the pots
• Easy 1 point calibration
• Takes 4 x 1.5v batteries (included).

HI-98331 is supplied with:

• HI-73331 penetration conductivity probe, (x4)
• 1.5V batteries, and>/li>
• full instruction manual.
