Supported Applications
The Rotronic Series HC2A-AW is a water activity measurement head designed to measure the humidity and temperature of hygroscopic products. The series identity centers on high-accuracy determination of equilibrium humidity (0...100 %rh) or water activity (0...1 Aw). Documented applications include the Food, Pharmaceutical, Chemical, and Cosmetics Industries.
Operating Conditions & Performance
The HC2A-AW series operates within an ambient temperature range of -40 to +85 °C. The sensor element is identified as HYGROMER WA-1. Accuracy at 23 ±5 °C is specified as ± 0.008 aw / 0.8 %rh / ±0.1 K, with a repeatability up to ±0.008 aw and long-term stability of < 1 %rh per year under normal conditions.
Storage conditions are rated for -40...+85 °C at 0...100 %rh (non-condensing). The device features an IP65 protection rating and includes a stainless steel wire mesh filter. A response time of 1–2 minutes is documented in the instruction manual.
Key Performance Specifications
- Sensor: HYGROMER WA-1
- Accuracy @ 23 ±5 °C: ± 0.008 aw / 0.8 %rh / ±0.1 K
- Operating Conditions: -40...+85 °C, 0...100%rh (non-condensing)
- Long-term Stability: < 1 %rh / year (normal conditions)

Configuration Options
The series is offered in two primary configurations distinguished by their electrical connection and cable length, enabling integration with different indicator systems.
Connector & Interface Options
- HC2A-AW: Features an HC2 connector with a 1m cable. Compatible with HygroLab indicators and HygroSoft software (with AC3001).
- HC2A-AW-USB: Features a USB-A connector with a 3m cable. Compatible with PC-based data acquisition via HygroSoft; not compatible with HygroLab.
Housing & Physical Attributes
The measurement head has overall dimensions of Ø68 x 65 mm and weighs 540 g. The housing material consists of Aluminum, stainless steel, and PC (polycarbonate). Both variants include an ON/OFF touch button and a green LED status light ring.
Accessories & Consumables
The series supports various sample holders and disposable containers to prevent cross-contamination:
- Sample Holders: WP-14-S (V2A steel, 14 mm height), WP-40 (Brass/nickel-plated, 40 mm height), WP-40TH (Brass/nickel-plated, 40 mm height).
- Sample Containers: PS-14 and PS-40 disposable containers.
Key Product Differences
The primary distinction between the HC2A-AW and HC2A-AW-USB models lies in their connectivity interface, cable length, and software compatibility. The HC2A-AW utilizes an HC2 connector for connection to dedicated indicators like HygroLab, while the HC2A-AW-USB employs a USB-A connector designed for direct PC interfacing via HygroSoft.
Both variants share identical sensor technology (HYGROMER WA-1), accuracy specifications, operating temperature ranges (-40...+85 °C), and physical dimensions. The choice between models depends on the required downstream data processing equipment: indicator-based systems or PC-based software environments.
