Comet H6520 - remote CO2 concentration thermometer hygrometer with Ethernet interface and two relays
| Previous | 32 / 144 | Next |
Temperature, humidity, CO2 level sensor with two output relays. Humidex reading.
Sensor H6520 is designed for online monitoring of temperature, relative humidity of air without aggressive substances. Other devices are controlled by two relay outputs.
High precision capacitive polymer sensor ensures excellent long term calibration stability and ultimate accuracy. Measured values are also converted to other humidity interpretation: dew point temperature, absolute humidity, specific humidity, mixing ratio and specific enthalpy.
The CO2 measurement is based on a 2-source, 2-beam process. CO2 measurement with long-term stability is guaranteed thanks to the proven non-dispersive infrared (NDIR) CO2 measurement cell. The unique patented auto-calibration procedure compensates for aging of the infrared source and guarantees high reliability, long term stability and eliminates the need of periodical recalibration in the field.
