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: The Advantages of Portable Gas Detector
- Small size, easy to carry, good quality and low price Portable gas detectors are usually small in size, so they are very convenient to carry and can be used at any time. In addition, high-quality portable gas detectors mainly use high-performance sensors, and high sensitivity is its most significant feature. This portable gas detector can visually display the gas concentration on site, and the standby time is longer than other products of the same type.
- Start-up detection, no need to set parameters. Before the factory leaves the factory, the parameters and values in the portable gas detector have been set, and the customer only needs to start the detection.
- Strong adaptability and a wide range of applications. The gas detectors can also be used in places that people cannot enter or cannot reach. Equipped with an external pump, this avoids the danger of letting the staff go to the detection first. The design of the pump extension pipe can be used in places such as cold rooms, refrigeration workshops, tunnels and other closed places where toxic gas leaks. In addition, the portable gas detector also adopts a waterproof, dustproof and explosion-proof design, and cooperates with a replaceable in-line gas sensing module, making it an ideal tool for safety detection on the job site today.
- Simple calibration steps General professional portable gas detectors have the characteristics of simple calibration steps. During the detection process, technicians only need to use the magnetic programming tool to start the calibration process. The detector will automatically start calibration as soon as the gas is supplied, and if the signal has started to be in a relatively stable state, the combustible gas detector will record the initial data and prompt the technician to disconnect the gas source.
