TG9XX8 series Duct mount CO2 transmitter for ventilation | Tongdy® - 1

CO2 Duct Transmitter With Temperature and RH% Detection Model: TG9XX8 Real time detection carbon dioxide of the air duct Detection high accuracy temperature and relative humidity Smart sensor probe with extendable probe may be easily installed into any With the water-proof and porous film around the sensor probe Up to 3xanalog linear outputs for measurements Optional Modbus RS485 interface With or without LCD display Optional Modbus RS485 communication interface. temperature or relative humidity in air ducts. Designed for real time detecting carbon dioxide, With LCD or without LCD selectable NDIR infrared CO2 sensor inside with special Self LCD display real-time measurements of CO2, Calibration and up to 15 years’ lifetime. It makes CO2 measurement more accurate and reliable. temperature and relative humidity. Combined temperature and humidity digital sensor Simple and smart design and installation of sensor probe with a water-proof and porous film provide a high accuracy measurement in full range. Extendable probe meets more air duct systems Provide up to 3 analog outputs (0~10VDC or 4~20mA or 0~5VDC) for CO2 temperature and relative humidity. Detection Focus Carbon Dioxide (CO2) Indoor CO2 level is a universal accepted parameter for the condition of indoor ventilation and air quality. A time period can be preset from 1 to 24 hours, e.g. 5 hours, then the monitor can display CO 2 average level during this period, which provides an objective and true data for the measurement of the air quality in a certain space. Non-dispersive infrared (NDIR) CO2 sensor with more than 10-year lifetime ABC self-calibration technology guarantees reliable CO2 measurement Rapid response, high stability and consistency
