WebSensor - remote CO2 concentration thermometer hygrometer with Ethernet interface

code: T6540

CO2 concentration, temperature and relative humidity t-line Web sensor. Remote alarm.


Web Sensor with built-in CO2 concentration, relative humidity and temperature sensors.

carbon dioxide

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.

WiFi Router Easy wireless communication using Web Sensor and optional  Wireless TP-LINK router.

 

Included in delivery:

 

Green LED shines - CO2 concentration 0 to 1000 ppm

Yellow LED shines - CO2 concentration 1001 to 1200 ppm
