OC‑1000 portable multi‑parameter monitor simultaneously measures CO, H2S, SO2, O2, TVOC, dust concentration, temperature and humidity. Compact portable structure, real‑time data display, suitable for industrial site inspection, confined space detection and environmental air quality monitoring.
Description:
The OC-1000 Portable Multi Gas Analyzer is an industrial-grade pump-suction environmental monitoring instrument designed to detect multiple hazardous gases, particulate dust, temperature and humidity simultaneously. It supports detection of Carbon Monoxide (CO), Hydrogen Sulfide (H₂S), Sulfur Dioxide (SO₂), Oxygen (O₂) and TVOC, making it suitable for confined space entry, chemical plant inspection, sewage treatment, mining, tunnel construction and indoor air quality assessment.
Equipped with a built-in sampling pump, the OC-1000 actively draws air samples into the detection chamber, which helps shorten response time and improve measurement stability. The laser dust detection module can monitor particulate matter concentrations such as PM2.5, PM10 and TSP, while the integrated temperature and humidity module provides additional environmental context for on-site assessment.
The device adopts a 3.5-inch industrial color screen, displaying real-time concentration values, measurement units, alarm status and historical trend curves. It supports large-capacity data storage, computer data export and optional on-site printing. With multi-parameter detection, flexible configuration and portable operation, the OC-1000 is suitable for industrial safety monitoring, environmental inspection and emergency response scenarios.
