Sensors & Transmitters

Smart Sensor Module for Cold Rooms:

• Most comprehensive sensor module measuring all key parameters responsible for uniform ripening which are Temperature, RH, Pulp, Ethylene and CO₂
• Sensor module communicates on RS 485 hence no transmission losses over long distances very typical to cold storages
• IP-65 housing designed for harsh environment which are prevalent for ripening chambers
