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 a formaldehyde detector?
- Sensor: The formaldehyde(CH2O) detector usually adopts the electrochemical sensor method, and the sensor type is observed through the air inlet of the detector.
- Accuracy: Formaldehyde concentration is accurate to two decimal places, that is, accurate to 0.01mg/m3. sisco detectors are designed in strict accordance with the standard.
- Standby time: Standby time is the easiest and most effective way to judge whether a formaldehyde detector is an electrochemical sensor or a semiconductor sensor.
- Manufacturer: Search the manufacturer's website and manufacturer's name, and regular manufacturers can find the official website. sisco is a popular detector supplier trusted by many customers.
