Product Description
OC-1000 Handheld Gas Detector is a pump-suction intelligent portable multi gas detector independently developed by Oceanus. It adopts a 3.5-inch industrial IPS color screen, supports customized matching of Ozone (O₃, ground-level ozone), VOC (Volatile Organic Compounds), NOx (Nitrogen Oxides), combustible gas, toxic gas and particulate matter sensors (PM2.5/PM10, Particulate Matter 2.5 / Particulate Matter 10). Built-in adjustable suction pump, mass data storage and optional printing module, widely applied in summer ozone law enforcement inspection, factory fugitive VOC&NOₓ leakage detection, environmental site monitoring and confined space safety detection.
Core Features
- Equipped with a 3.5-inch industrial IPS high-definition color screen, the OC-1000 ensures clear data display even under strong outdoor sunlight, meeting high-brightness field inspection requirements.
- The detector supports fully customizable sensor combinations, including Ozone (O₃), Volatile Organic Compounds (VOC), Nitrogen Oxides (NOx), particulate matter (PM2.5/PM10), toxic gases, combustible gas, and temperature & humidity, adapting to diverse air quality monitoring scenarios.
- Built with an adjustable high-precision suction pump, the device provides stable and uniform gas sampling, ensuring accurate and repeatable detection data in complex outdoor and industrial environments.
- It supports multiple international concentration units including PPM, %VOL, %LEL and mg/m³, which fully complies with global environmental testing and industrial safety standards.
- Dual-level audible and visual alarm thresholds are freely configurable. It can instantly trigger over-limit reminders for ozone, VOC and NOₓ pollution, helping operators respond quickly during summer ozone pollution inspections.
- The instrument supports storage of up to 100,000 groups of detection data, with professional PC software for data export, analysis and report generation, realizing traceable monitoring records.
- Optional accessories such as a micro thermal printer and high-temperature sampling probe expand application boundaries, supporting on-site data printing and high-temperature flue gas sampling.
- With CE, RoHS, ATEX and explosion-proof certifications, the OC-1000 is safe and reliable for industrial, chemical, outdoor environmental and potentially flammable working sites.
