Description:
The OC-1000 portable multi gas detector is equipped with a high-precision electrochemical H2S sensor specially designed for hydrogen sulfide monitoring. The dedicated H2S electrochemical sensor delivers fast response time ≤20s, stable signal output and excellent repeatability, supporting accurate real-time measurement of hydrogen sulfide gas in complex industrial environments.
This handheld H2S gas detector adopts built-in adjustable pump suction sampling, which can rapidly extract gas samples from confined spaces, sewers, mining tunnels and chemical workshops. It supports multiple concentration display units including ppm, %vol and mg/m³, with two-stage adjustable audible-visual alarm thresholds to remind operators once H2S concentration exceeds safety limits.
With large-capacity data storage for up to 100,000 groups of H2S detection records, test data can be exported to computer via supporting software for safety analysis and record filing. The device carries CE, CNEx and ATEX certificates, fully compliant with industrial safety standards for hydrogen sulfide hazard inspection.
Features:
Semiconductor technology of ultra low power 32 bit microprocessor, 24 bit ADC acquisition chip, so with the high accuracy.
3.5 inch IPS industrial grade color screen.
Support Chinese or English operation menu.
Gas concentration unit available for PPM, %VOL, mg/m3.
For 1~5 gas detecting, gas type all be customized, supporting the PM2.5 particle counter sensor, and humidity sensor, etc.
Internal sampling pump for suction, the suction strength is adjustable in different level.
Explosion proof grade is Exia ⅡCT4.
Function:
Inspect the gas concentration and alarm when it reaches preset alarm level.
With auto-test and data recover function.
One-key operation to restore to factory default setting.
Temperature and pressure compensation.
Adjustable two-stage audible-visual alarm threshold value.
Powered by rechargeable lithium battery with big capacity.
Working under the micro negative pressure is available.
Overload protection, over charge protection, anti static interference, anti magnetic interference, etc.
- Sewage & Wastewater Treatment Plants
Sewage pipelines, septic tanks, sludge workshops and underground drainage wells easily produce hydrogen sulfide from organic decay. The built-in pump can draw gas from deep confined spaces to test H2S concentration before maintenance.
- Mining & Tunnel Construction
Coal mines, metal mines and underground tunnels generate H2S from mineral decomposition. The two-stage audible-visual alarm warns workers when toxic H2S exceeds safe limits during excavation and tunneling operations.
- Petroleum, Oil & Gas Stations
Oil refineries, natural gas pipelines, LPG stations and oil storage tanks contain hydrogen sulfide in crude gas. Inspectors carry this handheld monitor for regular leak detection and daily safety patrols.
- Chemical & Pharmaceutical Factories
Chemical synthesis workshops, waste chemical storage areas and pharmaceutical fermentation workshops release H2S by-products. It supports continuous spot monitoring with large data storage for compliance reports.
- Municipal Sanitation & Landfill Sites
Domestic waste landfills, garbage transfer stations and compost yards accumulate H2S under anaerobic conditions. Portable design enables mobile patrol monitoring across the whole site.
- Confined Space Operations
Manholes, underground pipe corridors, storage tanks and reaction vessels are typical confined spaces with hidden H2S risks. The adjustable sampling pump quickly extracts internal gas before staff enter for work.
- Metallurgy & Coking Plants
Coking furnaces, smelting workshops and waste residue yards produce hydrogen sulfide during high-temperature processing, real-time H2S detection prevents poisoning accidents.
