OptiCal Humidity & Temperature Probe Calibrator
Self-contained probe calibrator with a built-in chilled mirror reference for national-standard traceability.
Key Features
- Built-in precision chilled mirror reference instrument
- Generates 10 to 90% RH over +10 to +50 °C
- Chamber accommodates up to 5 probes or sensors, any brand/model
- Excellent chamber stability and uniformity
- Manual control or optional automated set-point programming
- Simple operation and maintenance
- Transportable for on-site calibrations
Overview
The OptiCal is a premium, self-contained calibrator for humidity sensors, featuring an integrated chilled mirror reference instrument that lets the operator perform calibrations traceable to national standards. Its insulated, temperature-controlled chamber accommodates up to 5 probes or sensors of any brand or model with maximum stability and minimal temperature gradients.
Working Principle
A humidity- and temperature-controlled chamber generates a stable test environment while an internal precision chilled mirror hygrometer provides the reference dew point measurement. Up to 5 probes under test sit in the same chamber and are compared directly against this built-in reference, either under manual control or via optional automated set-point programming.
Applications
Benefits
- National-standard traceability from an integrated chilled mirror reference — no separate reference instrument needed
- Calibrates 5 probes from any manufacturer simultaneously
- Insulated chamber minimizes gradients for more consistent results
- Portable enough for on-site calibration work
