Product Manual Datasheet
Built-in Chilled Mirror Reference Hygrometer
Features
Simple operation and maintenance
Easy calibration of relative humidity sensors
Excellent chamber stability and uniformity
Manual control or optional straightforward automated set point programming
Humidity and temperature-controlled chamber
Generate 10 to 90% RH over +10 to +50°C temperature
Built in precision chilled mirror reference instrument
Transportable to allow on-site calibrations
The OptiCal is a premium, self-contained calibrator for humidity sensors. It features an integrated chilled-mirror reference which enables the operator to perform calibrations that are traceable to national standards.
The calibration chamber accommodates up to 5 probes or sensors of any brand or model. The chamber is insulated, and temperature controlled for maximum stability and minimum temperature gradients.
