Humidity Sensor Calibration

Calibrate humidity sensors for clean rooms, production/manufacturing facilities, product warehouses and other places where humidity is critical to product quality. Humidity sensors used for monitoring/recording data loggers and hand-held devices require periodic calibration. In critical monitoring/recording installations, a single-point check with a hand-held unit only provides a single point at ambient condition, but its value is limited. In most cases, these sensors are hard wired and cannot be taken back to the lab; however, the portability and speed of the 5128A allows users to perform a three-point check on-site next to the sensor with the right equipment.

Insert the transmitter sensor or Unit Under Test UUT into the chamber, select a set point, and the 5128A chamber will quickly reach a stable and uniform temperature and humidity environment. Use at least three to four calibration points distributed across the humidity range.
