No matter what kind of gas detector it is, it will have an alarm function, mainly so that when the instrument detects that the target gas concentration in the environment exceed a certain concentration, the gas detector will make alarm. The accuracy of the detection results of an instrument is an important condition for issuing a correct alarm, and the calibration of the gas detector is an important guarantee for achieving this condition.
A gas detector is an instrument tool for gas leakage concentration detection, including: portable gas detectors, fixed gas detectors, online gas detectors, etc. Gas sensors are sensors used to detect the composition and content of gases. When purchasing a gas alarm, the manufacturer will basically instruct you on how to adjust the gas alarm, and will also remind you that the gas alarm requires regular calibration and maintenance. However, many customers will not understand it because they have already been adjusted when purchasing. Why the gas leak detectors need to be calibrated by standard gas cylinder regularly?
1. The accuracy of the instrument is an important prerequisite for issuing an alarm when the concentration of toxic and harmful gases or combustible gases in the detected environment reaches the preset alarm limit. Accurate and timely alarms are the guarantee for personnel safety and production safety.
2.The accuracy of the detector based on the sensor. Electrochemical sensors and catalytic combustion sensors will be affected by certain substances in the environment during use and gradually change or even become poisoned and fail. At this time, regular calibration of gas alarms is completely necessary.
3. At present, all gas alarms have not got rid of the relative measurement method. Because of this, the instruments need timely maintenance and calibration. Only through correct detection and calibration can the accuracy of the results detected by the instrument be guaranteed.
4. In order to ensure that the error of the instrument test results does not exceed the normal range, frequent calibration is also necessary. Just like our watches, we often correct them with the standard time to ensure the accuracy of the time displayed by the watch. For gas alarms whose detection results involve the safety of personnel, accuracy is even more important.
5. The calibration cycle is determined according to the location, frequency of use and impact on the production process of the gas alarm. The calibration cycle can be 3 months, 6 months or 12 months.
The accuracy of the instrument is an important prerequisite for issuing an alarm when the concentration of toxic and harmful gases or combustible gases in the detected environment reaches the preset alarm limit. Correct and timely alarms are the guarantee for personnel safety and production safety. When the instrument leaves the factory, regardless of whether it is used or not, or whether the instrument is easy to use or not, the instrument must be calibrated regularly to achieve the purpose of minimizing the error of the instrument's test results and achieving high accuracy. For those in the security industry, whether it is a portable gas detector or a fixed gas detector, it must be accurate and reliable, and there is no room for sloppiness. The best way is to calibrate and maintain the detector correctly and regularly, which shows the importance of regular calibration.
