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: Tips for using sisco portable explosion-proof gas detector
Any gas detector has a fixed detection range, and the measurement can only be completed within this range, otherwise, the measured result is much lower than the value of your environment. In addition, measuring over the range for a long time will cause damage to the sensor, so the correct result cannot be obtained in the measurement range later.
sisco gas detectors have a limited service life. Even if they are not used frequently, they will still experience aging. In general, among the portable gas detectors, the photoionization detector has the longest lifespan of about four years; the lifespan of the LEL sensor is the second, which can be used for more than three years; the lifespan of the electrochemical-specific gas sensor is relatively short, generally within one to two years; the oxygen sensor can only be used for about one year.
Therefore, be sure to read the instruction carefully before using a portable gas detector, and use it within the validity period of the sensor. If it is found to be expired, it needs to be replaced immediately. The detector needs to be calibrated and tested frequently.
