How to set the alarm value of the gas detector
The use of gas detectors is becoming increasingly widespread, whether it is for environmental monitoring, safety production, scientific research experiments, etc. Gas detectors are needed, and in some cases, sound and light alarms are required to provide a prompt when the detected gas concentration reaches a certain value. So, how to set the alarm value?
Alarm point setting: Conventional factory only has A1 alarm value and A2 alarm value; TWA alarm value, S alarm value, and low concentration alarm value can be set separately according to user requirements.
a. A1 alarm value: also known as the first level alarm value, when the instrument detects a gas concentration higher than the A1 set value, the instrument will simultaneously emit sound, light, and vibration alarms. The alarm value and type can be customized.
b. A2 alarm value: also known as the second level alarm value, when the instrument detects a gas concentration higher than the A2 set value, the instrument will simultaneously emit sound, light, and vibration alarms. The alarm value and type can be customized.
c, Low concentration alarm value: When the instrument detects that the gas concentration is lower than the set value, it will simultaneously emit sound and light, vibration type alarms. The alarm value and type can be customized.
d. TWA alarm value: The instrument records measurement data every 10 minutes, recording 48 data points within an 8-hour time period. When the average value of these 48 data points is higher than the TWA alarm value setting value, the instrument will simultaneously issue an audible and visual alarm. The alarm value and alarm type can be customized.
e. S alarm value: The instrument records measurement data at regular intervals, recording 15 data points within a 15 minute time period. When the average value of these 15 data points is higher than the set S alarm value, the instrument will simultaneously issue an audible and visual alarm. The alarm value and type can be customized.
