H2O Analyzer
Type: Highly stable analyzer for accurate H
2
O measurements.
Range: H
2
O range: 0 to 100% RH
Sensor: The CI-340 uses a humidity sensitive capacitor to measure the relative humidity. Its range is 0-100% with
an accuracy of +/-2% at 10% RH and +/-3.5% at 90% RH. The response time of the sensor is about 15 seconds.
Typical Signal: The sensor electronics typically puts out a 0.5V signal for 50% RH, which is
amplified to 2.34V and measured with a 16bit ADC.
