Note: It is recommended, where possible, that the LPN series humidity/temperature sensor is mounted vertically with the orange protective cover at the bottom to help prevent moisture build up on the sensor in high humidity situations. This position can also help during calibration, allowing easier access for the calibration kits with a reduction in the spillage of calibration fluids.
LPN-H-CAL – Calibration System
The LPN-H-CAL system is designed to allow in situ calibration of LPN-H-W and LPN-H-D humidity transmitters.
The LPN-H-CAL system consists of canisters containing humidity regulating salt solutions that replace the protective filter on the sensor.
