产品介绍
Humidity Calibrator Stand-alone calibrator for relative humidity (RH) sensors providing humidity and temperature profiling with a built-in, NIST traceable optical reference hygrometer.","• Perform RH sensor calibration in-house • Simple and easy to use • Fully self-contained system • Digital control of temperature and relative humidity • Range 10% to 90% RH over 10° to 50°C chamber temperatures • Integrated precision reference hygrometer • Best measurement capability <2% of reading","Precision Calibration","For the user of relative humidity sensors there is always a question over the calibration accuracy and stability of the instruments in use. RH sensors provide economical measurement but require regular calibration and adjustment for correct performance over extended time periods. It is common for RH sensors to require calibration and adjustment at three or six month intervals, depending on the criticality of the measurement process.","Opti-Cal provides in-house calibration of RH sensors, without the need to send them to a NIST traceable laboratory. For a relatively low capital investment, Opti-Cal will provide calibrations that are directly traceable to National Institute of Standards and Technology over a wide relative humidity range, and at any set temperature from 10° to 50°C*.","Integrated System","Opti-Cal is a portable, fully self-contained humidity\/temperature calibrator. The system consists of a humidity\/temperature controlled chamber that can house up to six or more humidity sensors, depending on their physical dimensions. Temperature and humidity within the chamber are closed-loop controlled and continuously monitored by a precision optical reference hygrometer. Opti-Cal work 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 thermo-electric heat pump arrangement for maximum stability and minimum temperature gradient. The saturator assembly can be filled easily with distilled water 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 115 VAC power.
