Relative Humidity Calibrator OPTI-CAL with cooled miror integrated
Relative humidity range : 10...90% RH with a 0.2 % HR stability (20…80% RH)
Temperature range : + 10°C*...+ 50°C with a ± 0,1°C stability
Chamber dimensions : L=105 x h=105 x P=160 mm (V=2 dm3)
Integral cooled miror reference hygrometer, accuracy :
Humidity : < 1% RH between 10 and 70% RH & < 1,5% RH between 70 et 90% RH
Temperature : < 0,1°C
Humidity and temperature controlled by 2 separate sensors to the reference instrument
Humidity generation by mixture of flow dry and saturated air
Temperature generation by a four-zone-Peltier heat pump
Double skin chamber for a maximum stability and a minimum temperature gradient
Stability time between 2 levels : < 10 minutes
Humidity and temperature controlled chamber : manual or automatic (PC)
Calibrator dimensions : L= 520 x H=290 x P=420 mm
Weight : 20 Kg
Power supply : 85-264 VAC, 47-63 Hz, 150 VA
Delivered with a 5 ports door, the OPTI-SOFT software and an UKAS calibration certificate
* Lowest temperature set point = 10°C below ambient
