The Bacharach Multi-Zone Ethylene Monitor is designed specifically for the food industry, offering accurate and stable ethylene gas monitoring in fruit and vegetable ripening environments. It ensures reliable performance even in areas with fluctuating temperature and humidity. The monitor supports up to 48 sampling points and uses NDIR sensor technology to measure ethylene (R-1150, C₂H₄) at concentrations from 10 to 10,000 ppm. With a sensor lifespan of up to 10 years, integrated 80 dB audible alarm, and digital communication via Modbus RTU, this device is easy to integrate into building and process control systems.
