HH2 Moisture Meter - Readout Unit
· Holds multiple user-defined soil types · Stores up to 2000 time-stamped readings · Includes PC data collection software
The Moisture Meter type HH2 is a versatile readout unit for use with Delta-T Devices soil moisture sensors: the Profile Probe, ThetaProbe, SM200 and WET Sensor.
The HH2 readout unit offers impressive functionality in a compact, hand-held unit, designed for field use. Readings are displayed on the LCD and can be stored to memory for later download to a PC.
The unit can be operated with one hand, for convenience in the field. Each time-stamped reading includes a unique sample number, a plot identification number (A to Z), and a sensor location number (1 to 255).
Data is transferred to a PC using the RS-232 cable provided with each unit. The HH2Read Windows PC software provides a data import wizard for direct download into Excel or other PC spreadsheet packages, or into irrigation scheduling programs. Alternatively, data can be downloaded in comma-separated ASCII data file (.CSV) format.
