GE’s General Eastern Humilab is a NIST-traceable relative humidity generator and calibration chamber that is continuously monitored and controlled by a chilled mirror hygrometer and precision RTD.
The Humilab system is water-jacketed for thermal stability and facilitates cost-effective calibrations of relative humidity sensors, probes, transmitters, recorders, and data loggers.
Notice: As of November 2015, Humilab has transitioned to Life Cycle Phase 3 – Repairs & Spare Parts Support. Repairs, accessories, and parts support will continue for the Humilab for a period of time, by parts availability.
