BL765 Humidity Generator (5~95%RH)

IESLBD — Wed, 22 Oct 2025 03:48:35 +0000

The BL765 is a bench-top humidity generator for calibrating a large workload of probes in the laboratory or on site in the field. The system comprises a humidity and temperature controlled chamber that can house up to six humidity sensors. The BL765 works by time-proportioning the flows of dry and saturated air according to the pre-selected relative humidity value. The chamber temperature is controlled by a four-zone Peltier heat pump arrangement for maximum stability and minimum temperature gradient. The saturator assembly can be filled easily with the distilled water reservoir at the front of the unit and the easily accessible desiccator can be re-charged by heating when required.
