Product catalog summary
Sensor Specifications
The HYGROMER HT-1 sensor offers high accuracy and repeatability with up to ±0.5 %rh and excellent long-term stability of less than 1 %rh per year in clean air. It features smart electronics based on Rotronic’s AirChip3000, which calculates dew/frost points, generates alarms, and allows for hot-swapping of probes without re-adjustment.

Flexibility and Compatibility
The sensor provides user-scalable analog output signals (2x 0…1V) and a digital interface via UART, making it compatible with Rotronic’s HygroClip2 devices and OEM applications. The HW4 software and service cable AC3001 are required for full functionality.

Probe Types and Applications
Various probe types are available, including HC2A-S, HC2A-SH, HC2A-S3, and HC2A-SM, each offering outstanding accuracy, repeatability, and long-term stability. These probes are suitable for industries such as pharmaceuticals, meteorology, food, building services, and textiles.

High Precision and Standard Precision Probes
High Precision probes are factory-adjusted at 23°C and calibrated at multiple humidity levels, offering an accuracy of ±0.5 %rh. Standard Precision probes are adjusted at 23°C with an accuracy of ±0.8 %rh. Both types use the HYGROMER HT-1 sensor element.

Computer Connection and Filters
The AC3001 cable allows direct USB connection to a computer for probe parameter adjustments. Various filter options are available, including polyethylene and PTFE, suitable for different environmental conditions.

Extension Cables
Extension cables allow for increased distance between the probe and reading device, with passive connections up to 5m and amplified connections up to 100m using the AC3003 cable.

Technical Information
The HC2A probes operate with a supply voltage of 3.3 to 5 VDC, have a current consumption of approximately 5 mA, and offer protection rating IP65. They feature a digital interface with UART and analog outputs for humidity and temperature, which are freely settable with HW4 software.

Graphical Data
The document includes graphical representations of temperature and humidity windows, illustrating the operational ranges and accuracy levels of the probes.
