Product description:
OC-850 portable multi gas detector is a highly customizable industrial gas safety monitoring device. This configuration supports simultaneous detection of NO₂ (Nitrogen Dioxide), SO₂ (Sulfur Dioxide), CO (Carbon Monoxide) and PM particulate matter, and supports flexible customization of 1~5 kinds of target gases in total.
It is compatible with Electrochemical, NDIR, PID and semiconductor sensors. Dual sampling modes are optional: standard diffusion sampling and optional 1L/min pump suction sampling. Equipped with imported industrial high-precision sensors to ensure stable and accurate test data.
LCD screen synchronously displays real-time gas concentration, gas name and alarm status. Built-in stainless steel filter screen blocks acid mist, smoke and dust to protect internal sensors and guarantee smooth airflow.
Supports Chinese & English bilingual menu, stores up to 9999 groups of alarm records, equipped with sound-light-vibration triple alarm. With Ex ib IIB T3 explosion-proof grade and IP65 dustproof & waterproof protection, continuous standby time reaches 100 hours (diffusion mode). Widely used in thermal power plants, waste incineration factories, smelters, environmental law enforcement flue gas sampling and atmospheric pollution monitoring.
Features:
- Custom multi-index detection: NO₂(Nitrogen Dioxide), SO₂(Sulfur Dioxide), CO(Carbon Monoxide), PM particulate matter, support 1~5 gases flexible matching
- Dual sampling modes: diffusion sampling as standard, optional 1L/min pump suction sampling for flue pipeline deep sampling
- NO₂/SO₂/CO adopt independent imported electrochemical sensors, effectively reduce cross interference of acidic oxidizing flue gas
- Laser sensor for PM particulate detection, real-time monitoring dust concentration in exhaust gas and ambient air
- LCD real-time data display, support PPM, mg/m³, %VOL, %LEL multiple concentration unit switching
- Stainless steel anti-corrosion filter prevents acid mist and smoke from eroding sensors, extend service life
- Sound-light-vibration triple alarm, clear warning in noisy thermal power and incineration workshop
- Ex ib IIB T3 explosion-proof + IP65 dustproof waterproof, wide operating temperature -40℃~70℃, standby up to 100 hours
Function:
Monitor the gas concentration in the environment or confined space and alarm;
With self calibration function and zero calibration function, the gas monitoring is more accurate and reliable;
The factory setting function can be restored with one key to avoid the trouble of mis-operation;
With temperature and pressure compensation, it can perfectly compensate the gas concentration under different temperature and pressure environments;
Two level sound, light and vibration alarm, and the alarm point can be set by itself;
Large capacity lithium polymer rechargeable battery to ensure long working time;
Pump suction sampling mode (optional);
The shell adopts PC + TPE rubber coated design, which is durable, anti-skid, waterproof, dustproof and explosion-proof.
Applications:
- Thermal power plant, boiler room on-site sampling detection of flue gas NO₂, SO₂, CO and dust
- Waste incineration plant, smelter exhaust pollutant regular patrol monitoring
- Environmental protection law enforcement industrial enterprise atmospheric pollution random inspection
- Tunnel, traffic road ambient air toxic gas and particulate monitoring
- Chemical factory waste gas discharge spot testing
