How to set the alarm value of the gas detector?

The use of gas detectors is becoming more and more extensive. Whether it is environmental monitoring, safe production, or scientific research experiments, gas detectors are needed. In some cases, sound and light alarms are needed to give prompts when the detected gas concentration reaches a certain value. How to set the alarm value of the gas detector?

How to set the alarm value of the gas detector?

Alarm point setting: There are only A1 alarm value and A2 alarm value in the conventional factory; TWA alarm value, S alarm value and low concentration alarm value can be set separately according to user requirements.

a. A1 alarm value: also called the first-level alarm value. When the instrument detects that the gas concentration is higher than the A1 set value, the instrument will simultaneously issue sound, light and vibration alarms. The alarm value and alarm type can be customized.

b. A2 alarm value: also called the second-level alarm value. When the instrument detects that the gas concentration is higher than the A2 set value, the instrument will simultaneously issue sound, light and vibration alarms. The alarm value and alarm type can be customized.

c. Low concentration alarm value: When the instrument detects that the gas concentration is lower than the set value, the instrument will simultaneously issue an audible, visual, and vibration type alarm. The alarm value and alarm type can be customized.

d. TWA alarm value: The instrument records the measurement data every 10 minutes, recording 48 data, that is, the data within an 8-hour period. When the average value of these 48 data is higher than the TWA alarm value setting value, the instrument will simultaneously issue an audible and visual type alarm. The alarm value and alarm type can be customized.

e. S alarm value: The instrument records the measurement data every once in a while, recording 15 data, that is, the data within a 15-minute period. When the average value of these 15 data is higher than the S alarm value setting value, the instrument will simultaneously issue an audible and visual type alarm. The alarm value and alarm type can be customized.

The above is about how to set the alarm value of the gas detector. The gas detector is widely used in industries and places, including chemical industry, pharmaceutical industry, gas station, oil and gas field, coal mine, granary, gas pipeline, closed environment, deep well, etc. Where there is gas, there is a gas detector.
