OC‑903 Portable CO₂ Gas Detector adopts stable NDIR sensor for carbon dioxide detection. Built‑in pump‑suction sampling, with data logging and triple alarm. Certified by CE, RoHS, CNEX, ATEX, suitable for greenhouse plant growing and confined space safety inspection.
OC-903 portable Carbon Dioxide CO2 gas detector with the famous brand Infrared sensor for CO2 gas inspection , with the inner pump and the data logger function, optional sensor for the temperature and humidity measurement.
OC‑903 handheld carbon dioxide detector is dedicated to CO₂ concentration measurement. Equipped with high‑performance NDIR infrared sensor, it delivers accurate and stable reading even under complex surroundings.
Built‑in adjustable pump‑suction sampling realizes quick on‑site gas intake. Temperature‑pressure compensation reduces environmental interference. 2.4‑inch IPS color screen shows real‑time readings clearly. Two‑stage adjustable audible‑visual‑vibration alarm triggers when CO₂ exceeds preset value.
It can store up to 100 000 groups of test data and support PC export. With complete certifications, it is widely applied in greenhouses, plant growing monitoring, farms, warehouses and confined‑space operation safety monitoring.
