Xtester-TGP Carbon Dioxide Transmitter with Temp.&RH
overview
| It is mainly used in the application of BAS in industrial buildings to real time monitoring carbon dioxide level, temperature and relative humidity. Also suitable for applications in plant areas such as mushroom houses. The lower right hole of the shell can provide expandable use. The external sensor probe to avoid internal heating of the transmitter from affecting measurements. White backlight LCD can display CO2, Temp and RH if required. It can provide one, two or three 0-10V / 4-20mA linear outputs and a Modbus RS485 interface. |
FEATURES
| 1.Real-time detect CO2 level of indoor environment 2.NDIR infrared CO2 sensor with Self-Calibration and up to 15 years lifetime 3.Humidity and temperature detection optional 4.Combined temperature and humidity sensor provide the highest accuracy in full range 5.Wall mounting with the external sensor probe with the higher accuracy of measurements 6.Backlit LCD display option can display CO2 measurement and temperature+ RH measurements 7.Providing one or three 0~10VDC or 4~20mA or 0~5VDC analog outputs 8.Modbus RS485 communication interface makes usage and test more convenient 9.Smart structure with the simple installation and wiring 10.CE-Approval |
