Thin-film aluminum oxide moisture sensor probe.
Compatible with all GE Panametrics aluminum oxide moisture
probes.
All moisture probe calibrations are traceable to National Institute of
Standards and Technology (NIST) standards or National Physical
Lab, U.K. (NPL) as approved by Irish Laboratory Accreditation
Board (ILAB).
Overall Calibration Range Capability:
-110 to 60°C (-166 to 140°F)
Available Calibration Range Options:
Standard:
-80 to 20°C (-112 to 68°F) with data to -110°C (-166°F)
Ultra-Low:
-110 to -50°C (-166 to -58°F)
Extended High:
-80 to 60°C (-112 to 140°F) with data to -110°C (-166°F)
Accuracy:
±2°C from -65 to 60°C (-85 to 140°F)
±3°C from -110 to -66°C (-166 to -87°F)
Repeatability:
±0.5°C from -65 to 60°C (-85 to 140°F)
±1.0°C from -110 to 66°C (-166 to -87°F)
Note: All dew/frost point outputs are available in °C, °F or K.
