Key parameters
Rh Generation Range
5 to 95% RH
Rh Stability Uniformity
±0.5% RH stability; ±0.5% RH uniformity across chamber
Stabilization Time
Typically <5 min for full stability from 10% RH step changes
Control Probe
HC2A-S: ±0.8% RH accuracy; ±0.1°C temperature; ±1% RH/year long-term stability
Probe Capacity
Validate up to 7 probes simultaneously (8-port adaptors for 12–25 mm diameters)
Probe Signal Interface
7× 24 V excitation (incl. 1× 3.3 V); accepts 0–20/4–20 mA, 0–1/0–5/0–10 V
Fits portable humidity validation where you need a HygroCal100A divided-flow chamber to generate 5 to 95% RH and check up to seven probes at once.
Key advantages
- RH generation — 5 to 95% RH with ±0.5% RH stability and ±0.5% RH uniformity
- Speed — Typically <5 min to full stability from 10% RH step changes
- Capacity — Validate up to 7 probes; 8-port adaptors for 12–25 mm diameters
- Control — HC2A-S control probe; 4.3 in color touchscreen; automated procedures
- Logging — 2 GB internal memory; CSV download to USB
Typical applications
- Field or lab validation of RH transmitters and probes.
- Multi-probe batch checks in calibration workshops.
- Portable RH generation without a full climatic chamber.
Selection guide
- Probe ports / adaptors — Diameter set for your probes (12–25 mm class)
- Signals — 0–20/4–20 mA or 0–1/0–5/0–10 V acceptance on channels
- Power — 24 V DC adaptor (100–240 V AC); optional battery pack
- Ambient — Use within +5 to +40 °C ambient
Common mistakes
- Expecting climatic-chamber temperature sweeps — HygroCal100A is RH generation/validation focused.
- Omitting adaptor sizes for probe diameters outside the stock ports.
- Running outside +5…+40 °C ambient and blaming chamber uniformity.
When to RFQ / what to tell us
- Probe count, diameters, and signal types.
- Battery option yes/no; adaptor set.
- Quantity and ship-to.
