Dual channel NDIR high concentration CO2 sensor (100,000ppm~300,000ppm)

The TES0940 is a dual-channel optical (NDIR) high-concentration CO2 gas sensor that can measure the CO2 concentration from 100,000 ppm to 300,000 ppm.

TES0940 is a product that can be applied to agricultural products cold storage (CA), cold-chain system, food transportation, and mining industries that require high-concentration CO2 measurement. By monitoring the CO2 concentration, it makes the work environment safer for workers and helps to maintain the freshness of food to its destination.
