What is HH2?
The HH2 Moisture Meter is a versatile readout unit for use with Delta-T soil moisture sensors. It can be used with the PR2 Profile Probe (both analogue and SDI-12* versions), ML3 ThetaProbe, SM150T and WET Sensors.
Features
・Immediate display of water content
・Reads ML3, SM150T, PR2 (analogue and SDI-12) or WET Sensor
・Stores up to 1500 time-stamped readings
