Talking about Three Misunderstandings of Commonly Used Gas Alarms

Today, various types of industrial enterprises are increasingly using gas detection and alarm systems. In order to prevent poisoning of personnel and protect public property, gas detection and alarm systems have become "protective umbrellas." The alarm suddenly "dumb fire." Objectively speaking, the cause of alarm failure, quality factors accounted for only a small part, the vast majority of reasons must be attributed to people's misuse. How to use the alarm properly?

Misunderstanding 1: The alarm can be used permanently

Most companies now purchase gas detection alarms. They will not be replaced after installation and acceptance, and even exceed the useful life. This is very dangerous. Because the alarm is also an electronic product, the circuit board of the electronic product has a service life, and it will be aged after a long time. In particular, the lifespan of the alarm sensor has this very precise life span. Therefore, after a company purchases an alarm, it must be replaced or repaired at the end of its useful life. Toxic gas detectors are best to replace sensors or repair in 2 to 3 years. Combustible gas detectors are best to replace sensors or repair the machine in about 5 years. In addition, the alarm must be regularly dust and check whether the circuit board has aging or corrosion. Because the dust and other harmful substances corrode the sensing element covering the alarm, the sensitivity of the sensing element is reduced.

Misunderstanding 2: The gas alarm will not be maintained after installation

After any product purchase, maintenance is required, and gas alarms are regularly calibrated. In order to prevent dust from blocking the sensor pores, the instrument is insensitive, and measurement errors and data drift may occur due to inaccurate calibration. Regular maintenance can even prolong the service life of gas detection alarms, thereby saving the purchase cost for the company.

Myth 3: Catalytically combustible gas alarms can measure organic combustible gases (volatile organics)

Many customers have neglected the use of gas detection alarms in order to save purchase costs. Many companies have chosen catalytically combustible gas detectors that do not perform satisfactorily when measuring volatile organic compounds. This kind of detector not only has poor detection effect on such gases, but also has low accuracy and short service life. The correct selection should choose the PID photo ion sensor detector, although the price is slightly higher, but the measurement accuracy is high. It can effectively avoid the injury of personnel and make protective measures against gas leakage.
