Product Overview

      SM2170B carbon dioxide (CO2) sensor built-MG811 original electrochemical sensors, its lower accuracy, in response to customer demand for high-precision measurements of CO2, the products are all upgraded to a dual-beam infrared CO2 sensor. Products using RS485 interface, standard MODBUS-RTU protocol, enabling simultaneous multi-point monitoring, networking and remote.
     This product supports secondary development, users simply use any serial communication software module data query and set according to our protocol.
A carbon dioxide sensor uses non-dispersive infrared gas detection technology to detect the concentration of carbon dioxide gas, with high accuracy, long adjustment period, good reproducibility, wide measuring range, long life, free from other background gas (CH4, H2S, SO2, N2, O2, etc.) affect the advantages.
2, the sensor in the design of high-performance single-chip microprocessor and highly integrated digital circuits, simple structure, reliable performance, debugging, and maintenance.
    Caution:
1. Built-in device is a non-dispersive infrared CO2 sensor carbon dioxide sensor, the need for adequate electrical heating to achieve good condition, we recommend that you preheat at least five minutes, even up to 1-3 hours to warm up.
2. This product is used for greenhouses, environment, air quality, carbon dioxide detection device control. Suitable for detecting the concentration of carbon dioxide, carbon dioxide gas sensors tested concentration range: 0-5000ppm.
