NDIR Multi-Gas Sensor for TOC measurement CO2 100 ppm // CO2 1000 ppm // CO2 10000 ppm

Product catalog summary

Product Overview: The SILAREX NDIR Multi-Gas Sensor is designed for Total Organic Carbon (TOC) measurement, featuring three active measurement channels for CO2 detection at different ranges: 100 ppm, 1000 ppm, and 10000 ppm. It is equipped with on-board pressure compensation and supports Modbus ASCII/RTU communication.

Specifications: The sensor operates on the Non-Dispersive Infra-Red (NDIR) principle with dual wavelength. It requires a gas flow rate of 0.1 to 1.0 l/min and has mounting dimensions of 336 mm x 40 mm x 55 mm. The warm-up time is less than 2 minutes for start-up and less than 30 minutes for full specification.

Performance: The response time varies with flow rate, with a t90 response time of less than 4 seconds in fast mode. The digital resolution is 0.01 ppm for the 100 ppm range, 0.1 ppm for the 1000 ppm range, and 1 ppm for the 10000 ppm range. The sensor exhibits high repeatability and low linearity error.

Environmental Conditions: The sensor operates at ambient temperatures between +10°C and +40°C, with a storage temperature range of -20°C to +60°C. It can function in ambient humidity levels from 0 to 95% relative humidity, non-condensing.

Electrical and Communication: The sensor requires a 24 V DC supply voltage with an average power consumption of less than 6 W when the heater is on. It supports digital output via Modbus ASCII/RTU.

Recommendations: Recalibration is recommended at first initiation and periodically depending on application and ambient conditions. The sensor is available with various accessories such as insulation housing, gas cooler, particle filter, and gas pump.
