Overview
A portable oxygen detector can monitor O2 concentration in the range of 0 to 30% Vol or 0 to 100% Vol. Handheld gas detector provides sound, light and vibrating alarm, long working time with large capacity battery, easy to setting and operation,
Gas detectors can detect oxygen (O2) quickly
- sisco portable oxygen (O2) gas detector has an LCD dot matrix display to directly read out the gas type, unit, concentration, local time, etc.
- English/Chinese operations are supported.
- Gas concentration unit PPM and mg/m3 can be shifted quickly.
- Built-in micro-sampling pump, 10 grades of suction are available.
Explosion-proof certification.
USB interface to transfer data at high speed
- The handheld oxygen detector can download and print the stored data (optional).
- There is no need for personnel to manually record data in real-time, and the data is automatically stored in the instrument.
- Historical data can be viewed on the instrument or downloaded to a computer.
- USB interface, fast and convenient charging.

FAQs
Q1: What is a gas detector?
A1: A gas detector is an instrument for gas leakage concentration detection, including a portable gas detector, handheld gas detector, fixed gas detector, online gas detector, etc.
Q2: What does a gas detector detect?
A2: Combustible gases: Natural gas (methane), liquefied gas, coal gas (hydrogen), acetylene, pentane, alkynes, acetone, toluene, alcohols, hydrocarbons, light oil, etc.
Toxic gases: Carbon monoxide, hydrogen sulfide, ammonia, chlorine, oxygen, phosphine, sulfur dioxide, hydrogen chloride, chlorine dioxide and other toxic and harmful gases.
Q3: What is ppm of gas detector?
A3: Parts per million or "ppm" is often used as a fractional measure of concentration. For example, a methane (molecular) concentration of 2% means that 2 out of every 100 air molecules are methane. Likewise, a methane concentration of 2 ppm means that 2 out of every 1 million air molecules are methane.
Tips for Using sisco Oxygen Detectors
- Pay attention to regular calibration and testing.
- Pay attention to the detection interference between various sensors.
- Pay attention to the life of various sensors.
- Pay attention to the concentration measurement range of the oxygen detection instrument.
