Description:
OC‑901 portable pump‑suction 4‑in‑1 gas detector is customized for simultaneous detection of Carbon Dioxide(CO₂), Oxygen(O₂), Ammonia(NH₃) and Nitrogen Dioxide(NO₂), designed for complex industrial on‑site safety monitoring. It adopts multiple original imported high‑precision sensors: NDIR infrared sensor for carbon dioxide; high‑performance electrochemical sensors for oxygen, ammonia and nitrogen dioxide, realizing stable and accurate measurement for each target gas.
Built‑in inner pump enables pump‑suction sampling mode for ultra‑fast gas response, rapidly capturing real‑time concentration changes of four kinds of gases in working environment. The 2.4‑inch colorful display clearly shows gas type, real‑time concentration value, concentration unit, time, battery status and alarm status. Operation menu supports free switch between Chinese and English.
When any gas concentration exceeds preset alarm threshold, multi‑mode alarms including voice prompt, audible‑visual alarm and vibration alarm will be activated immediately. It effectively warns operators of oxygen deficiency, CO₂ accumulation, ammonia leakage and nitrogen dioxide toxic hazard. Alarm data storage function allows users to check historical alarm records on‑site.
Equipped with practical back‑clip, the detector can be clipped on work clothes for convenient mobile patrol inspection. Powered by 3.7V 4000mAh rechargeable lithium battery, continuous working time is more than 10 hours. It complies with Ex ib IIB T3 explosion‑proof standard and IP65 protection grade, suitable for damp and harsh industrial conditions. The housing is made of durable ABS & PC material. Aluminum alloy carry case is included for easy transportation and storage. 1‑year warranty is provided.
This four‑gas monitor is widely applied in chemical workshops, wastewater treatment plants, confined‑space operations, waste disposal sites, environmental law‑enforcement and industrial accident rescue sites for comprehensive multi‑gas risk detection.
