Delta-T HH2 Moisture Meter

The Delta-T HH2 Moisture Meter is a versatile hand-held readout unit designed for use with Delta-T soil moisture sensors such as ML3 ThetaProbe, SM150T, PR2 (analogue and SDI-12 versions), and WET Sensors. It provides immediate display of soil moisture content and can store up to 1,500 time-stamped readings for later download. The HH2 is perfect for field use due to its compact design, allowing for easy one-handed operation and quick data retrieval.

The readings are displayed on an LCD screen and can be stored in memory for later transfer to a PC using the included RS-232 cable or a USB to RS232 adapter. Data can be imported directly into Excel or other spreadsheet applications or used in irrigation scheduling programs.

Key Features & Benefits:

1. Immediate Display of Water Content:
   • The HH2 Moisture Meter instantly displays the soil moisture content, making it easy to monitor moisture levels directly in the field, ensuring timely decision-making for irrigation and other fieldwork tasks.
2. Wide Sensor Compatibility:
   • The HH2 is compatible with multiple Delta-T soil moisture sensors, including:
     • ML3 ThetaProbe
     • SM150T
     • PR2 (both analogue and SDI-12 versions)
     • WET Sensors
   • This flexibility ensures that the HH2 can be used in a wide range of soil moisture monitoring applications.
3. Data Storage and Time Stamping:
   • The unit can store up to 1,500 readings with time stamps, making it ideal for long-term data collection in field research.
   • Each reading includes a unique sample number, a plot identification number (A to Z), and a sensor location number (1 to 255), providing organized and detailed data for analysis.
4. Easy Data Transfer to PC:
   • Data can be downloaded to a PC using the RS-232 cable provided, or alternatively, using a USB to RS232 adapter cable (available separately).
   • HH2Read Windows PC software allows for easy import of data into Excel or other spreadsheet programs or directly into irrigation scheduling software.
5. Power Efficient:
   • The device operates on a 9V alkaline battery (6LR61/PP3), with a battery life capable of logging up to 5,000 readings, making it suitable for extended field use without frequent battery replacements.
6. Durability and Field Use:
   • With an IP54 rating, the HH2 Moisture Meter is dustproof and water-resistant, ensuring reliable performance even in challenging environmental conditions.
7. Compact and Portable:
   • The compact size (125 x 80 x 45mm) and lightweight design make the HH2 Moisture Meter easy to carry and operate in the field.
