Introduction to the Operation and Alarm System of Portable Gas Detectors
1, Long operating time of portable gas detector:
The operation time of a portable gas detector depends on the battery's operating time. There are dry batteries or rechargeable batteries, as well as two types of instruments that complement each other. Currently, the longer operating times on the market are 16 hours and 24 hours, which can be used by workers for two shifts. The actual application time may vary depending on the frequency and duration of the alarm.
2, The perfect alarm system for portable gas detectors:
Currently, portable gas detectors on the market generally have sound, alarm lights, and vibration alarms.
It should be noted that when confirming the sound alarm, not only should attention be paid to the detection distance and decibel value (such as at 30cm>95Db), but also to the penetration of the sound.
There is also a fall alarm function. If an operator falls and loses consciousness for more than 20 seconds, the instrument will automatically sound an alarm. If it continues for another 10 seconds, it will escalate to a high alarm. There is also an immediate alarm function. If the operator detects an emergency situation on site, they can manually trigger the button through the instrument to issue an alarm to the surrounding personnel. Both of these are exclusive patents of the American company Meisi An.
