Nowadays, various industrial enterprises are increasingly using gas detection and alarm systems. In order to prevent personnel poisoning and protect public property, gas detection and alarm systems have become a "protective umbrella". However, in several recent accidents, the alarm suddenly "misfired". Objectively speaking, quality factors account for only a small part of the causes of alarm failure, and most of the causes are attributed to improper use. So how to use the alarm correctly? Today I will start with three major misunderstandings to explain to you how to use alarms correctly.
Myth 1: Alarms can be used permanently
Nowadays, most companies purchase gas detection alarms and do not replace them after installation and acceptance. They even continue to use them beyond their service life. This is very dangerous. Because alarms are also electronic products, and the circuit boards of electronic products have a service life and will age over time. In particular, the life of the alarm sensor has a very precise service life. Therefore, after companies purchase alarm devices, they must replace or repair them when their service life expires. Toxic gas detectors are best replaced or repaired every 2 to 3 years. In addition, the alarm must be regularly dusted and checked to see if the circuit board is aging or corroded. Because dust and other harmful substances corrode the sensing element covering the alarm, it will reduce the sensitivity of the sensing element.
Myth 2: Gas alarms do not require maintenance after installation
Any product needs maintenance after purchase, and gas alarms must be calibrated regularly. This prevents dust from clogging the sensor pores, causing the instrument to become insensitive, and causing measurement errors and data drift due to untimely calibration. Regular maintenance can even extend the service life of gas detection alarms, thereby saving purchasing costs for enterprises.
Myth 3: Catalytic combustion combustible gas alarms can measure organic combustible gases (volatile organic matter)
Many customers ignore the effectiveness of gas detection alarms in order to save procurement costs. When many companies measure volatile organic compounds, they choose catalytic combustion combustible gas detectors that are not very effective. This kind of detector not only has poor detection effect and low accuracy for such gases, but also has a short service life. The correct selection should be to choose a PID photoion sensor detector. Although the price is slightly higher, the measurement accuracy is high. It can effectively avoid personal injury and take protective measures against gas leakage.
