TheOptiCalisabench-top,fullyself-containedhumidity/temperaturecalibrator

詳細(xì)介紹

The OptiCal is a bench-top, fully self-contained humidity/ temperature calibrator. The system comprises a humidity and temperature controlled chamber that can house up to five or more humidity sensors, depending on their physical dimensions. The humidity and temperature within the chamber are closed-loop controlled and continuously monitored by a precision chilled mirror reference hygrometer. The OptiCal 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 distilled water reservoir at the front of the unit and the easily accessible desiccator can be re-charged by heating when required. No other maintenance is necessary. The only external service required is a single phase power supply.



亮點(diǎn)

  • Precision relative humidity and temperature calibrator
  • Generate 10 to 90% RH over 10 to 50°C temperature
  • Integral cooled mirror reference hygrometer
  • Humidity and temperature profile generation for unattended verification of sensors
  • Transportable calibrator enables on-site calibrations
