Applications
Portable methyl bromide (CH3Br) gas detector is mainly used for entry-exit inspection and quarantine, fumigation treatment, container inspection, port environmental inspection, health quarantine, grain storage, agriculture, food industry and construction industry. Sisco gas detectors can be used to detect these areas, and if the concentration exceeds the standard, it will automatically alarm.

FAQs
p>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: How to choose gas detectors according to application scenes?
The selection of gas detectors differs from the industrial environments.
- Fixed gas detector: Such a gas detector is mostly used in industrial devices and production processes. It can be installed on a specific detection point to detect specific gas leaks.
- Portable gas detector: As the portable gas detector is easy to operate and compact, it can be carried to different production sites. In open occasions like open workshops for security alarms, a wearable diffusion-type gas detector is recommended because it can display the concentration of toxic and harmful gases continuously, in real time and accurately on site. If it’s used in a confined space, such as the reaction tank, storage tank or container, sewer or another underground pipeline, underground installations, cargo hold and tunnel, a multi-gas detector with a built-in sampling pump is recommended.
