WebSensor – remote CO2 concentration thermometer hygrometer with Ethernet interface
BRAND
CO2 concentration, temperature and relative humidity t-line Web sensor. Remote alarm.
Web Sensor with built-in CO2 concentration, relative humidity and temperature sensors.
A multiple point CO2 and temperature adjustment procedure leads to excellent CO2 measurement accuracy over the entire temperature working range; this is a must for process control and outdoor applications. The dual wavelength NDIR CO2 sensing procedure compensates automatically for ageing effects. The CO2 module is highly resistant to pollution and offers maintenance free operation and outstanding long term stability.
High precision capacitive polymer sensor ensures excellent long term calibration stability and ultimate accuracy. Dual line LCD is an advantage. Measured values are also converted to other humidity interpretation: dew point temperature, absolute humidity, specific humidity, mixing ratio and specific enthalpy.
The CO2 concentration is shown on the display or signaled by a color LED.
Processing and analysis of measured data:
- online in COMET Cloud
- COMET Database software
- integration into 3-party systems
Optional CO₂ measuring range extension from the standard 0 to 5,000 ppm up to 0 to 10,000 ppm (available at extra cost):
- Extended measuring range: 0 to 10 000 ppm
- Accuracy in extended range: 100 ppm + 5% of the measured value at 25 °C and 1013 hPa
