Moisture Measurement
Compatibility
Compatible with all GE aluminum oxide moisture probes:
M Series, TF Series, and Moisture Image Series. Each
probe type requires a diff erent type of I/O cable.
Calibration
GE moisture sensors are computer-calibrated to National
Institute of Standards and Technology (NIST) traceable
moisture concentrations.
