Gas detector is a kind of gas leakage concentration detection instrument tool, mainly using gas sensor to detect the existence of the gas type in the environment, gas sensor is used to detect the composition and content of the gas sensor.

What are the main gases of the standard four in one

The four-in-one gas detector can detect four kinds of gas at the same time: combustible gas, oxygen, hydrogen sulfide and carbon monoxide. It can detect some complicated production workshops and other places where there may be a variety of dangerous gases. No matter which kind of gas exceeds the standard, the gas detector will immediately give out the sound, flash and vibration alarm.

Principle of four-in-one gas detector

Four and a gas detector can install three to four sensors at the same time, for each sensor detect the gas concentration of signal processing, intuitive display on the instrument, the concentration of each gas more than the alarm value set, will send out alarm signal, mainly divided into two categories according to the sampling way, dispersive sampling detector, the gas detector is only harmful gas diffusion to instrument sensor location, can put the gas concentration detected signal, and is a kind of pump suction four combination gas detector, general equipped with sampling tube, the gas detector can stretch into limited detection space, The gas inside is pumped to the sensor's location for analysis to determine the safety of the confined space and hence its suitability for operation.

Gas detector is to remind the staff of potential danger at any time, take preventive measures in advance, effectively ensure the safety of life and property.
