Key parameters
Display
Backlit graphic LC; 1–3 decimal places; trend and alarm indication
Device Type
Humidity-temperature / water-activity hand-held with 2 probe inputs + RTC
Aw Modes
AwQuick (accelerated, typically ~5 min) and AwE (equilibrium) simultaneous dual-probe
Aw Display
Humidity shown as aw (1.000 aw = 100 %RH) in AW mode
Probe Inputs
2× HygroClip2 digital or analog (0–3.3 V, 12-bit); 5 VDC probe supply
Accuracy At 23C
Depends on probe; typically ±0.8 %RH / ±0.1 K with HygroClip2
Fits on-site water activity checks where you need a Rotronic HP23-AW-A—0–1 aW with dual HygroClip2 inputs, AW Quick results typically in 4–5 minutes, and logging to 10,000 records.
Key advantages
- Range — 0–1 aW; 0–100 %RH; −10…60 °C
- Inputs — 2× HygroClip2 or analog probes
- AW Quick — Typically 4–5 minutes; audible completion
- Memory — 10,000 log values; 8×250 capture
- I/O — Mini USB; HW4; 9 V or USB power; IP30
Typical applications
- Food / pharma aW spot checks.
- Bulk material stability screening.
- Mobile lab water-activity surveys.
Selection guide
- HC2-AW vs insertion probes
- HW4 Quick software need
- Calibration standards
Common mistakes
- Measuring without equilibrium awareness in standard mode.
- Wrong probe for sample type.
- Ignoring IP30 limits.
When to RFQ / what to tell us
