gas detector is based on the classification of detection targets, that is to say, all instruments used to detect gas composition and concentration are gas detectors, whether it is physical or chemical methods, as long as the instruments used to detect gas concentration in the environment are called gas detectors. However, many consumers do not know how to choose because they do not know enough about gas detectors. For this reason, Yiyuntian Xiaobian will introduce to you what you need to pay attention to when choosing gas detectors.

& nbsp;

& nbsp;

1. attention should be paid to the concentration range of the gas detector: when the gas is detected, its accuracy can only be guaranteed within its measurement range. if it exceeds the measurement range for a long time, it will cause fatal damage to the sensor, greatly shorten the service life of the sensor, high concentration of long-term work of toxic and harmful gas detector will also cause damage.

& nbsp;

2. Functional requirements for use: the general function of the gas detector is to detect gas concentration, alarm exceeding the standard, etc. But many customers need more than just these features. Signal output is on the one hand, it is necessary to need current output, digital signal output, voltage output and switch output. There may be other special requirements such as network interfaces and wireless signals. At the same time, data recording and processing are also more common requirements.

& nbsp;

3. protection requirements: whether explosion-proof safety level is applicable to the workplace, whether intrinsic safety is certified, has explosion-proof certification or only has intrinsic safety design. Anti-electromagnetic wave level.Because the electromagnetic wave will produce induced current and make the instrument reading value error or instability, the source of electromagnetic wave is generally radio walkie-talkie, radio, mobile phone and other electronic products that will emit electromagnetic waves.

& nbsp;

4. Convenience: light weight, small size, easy and comfortable wearing, easy maintenance.

& nbsp;

the matters needing attention in selecting the gas detector will be shared here first. in short, the gas detector can effectively carry out pre-disaster suppression, so that accidents that may cause disasters can be controlled in advance, while protecting and ensuring industrial safety and the safety of operators. the gas detector needs to be selected in combination with the specific use environment and required functions.
