±1% at 20-50% RH (Multi-point calibration NIST traceable)
Reset Rate*** 24 hours
Stability ±1% @ 20°C (68°F) annually, for two years
Linearity Included in Accuracy spec.
Operating Humidity Range 0-100% RH
Temperature Coefficient ±0.1%RH/°C above or below 25°C (typical)
Operating Temperature Range 10° to 35°C (50° to 95°F)
Scaling 0-100% RH
Calibration Offset Adjustable ±9.9% in 0.1% increments

*One side of transformer secondary is connected to signal common, so an isolation transformer or
dedicated power supply may be required.
**Specified accuracy with 24VDC supplied power with rising humidity.
***Reset Rate is time required to recover to 50% RH after exposure to 90% RH for 24 hours.
To maintain CE compliance the connected power supply must have a CE mark supporting LV + CE
directives.
