1. Primary standard: Integrated chilled mirror and
platinum RTD constantly measure test conditions
2. Precise: ±0.2% RH stability
3. Accurate: ±1% RH from 10% to 70% RH and ±1.5% RH from 70% to 90% RH
4. Versatile: 10% to 90% RH and 20°C to 30°C
5. Self-contained operation: Equipped with desiccant and water reservoir
6. Connects to temperature bath/circulator to
standardize test conditions
7. Connects to dry compressed air to extend desiccant
life indefinitely
8. Records and documents: 0 to 5 VDC, 4 to 20 mA
analog outputs and RS-232 digital data stream
9. Fast response: 10 minutes for 63% step change and
30 minutes to full stability
10. Quality design: Stainless steel chamber
11. Instant-on fittings for external dry air, circulation
of temperature controlled water and reservoir drain
12. Cost effective: Ability to calibrate several %RH
instruments at once
13. Ease of operation: Set to value you need by the front panel or via software for ramp and soak
profiles
14. Bright, easy to read control panel
