How to Set the Alarm Value of a VOC Detector?
With the continuous development of technology, new gas detectors are constantly emerging to help us solve the problem of detecting gases, including VOC detectors. At present, VOC detectors are widely used in various chemical sites because of their high precision, suitability for air detection, and ease of portability. How to set the alarm value of the VOC detector?
1. A1 alarm value: also known as the first alarm value, when the instrument detects a gas concentration higher than the A1 set value, the instrument will simultaneously issue an audible and visual alarm and a vibration alarm. The alarm value and type can be customized.
2. A2 alarm value: also known as the secondary alarm value, when the instrument detects a gas concentration higher than the A2 set value, the instrument will simultaneously issue an audible and visual alarm and a vibration alarm. The alarm value and type can be customized.
3. Low concentration alarm value: When the instrument detects that the gas concentration is lower than the set value, the instrument will simultaneously emit sound and light and vibration alarms, and can customize the alarm value and type.
4. TWA alarm value: The instrument records measurement data every 10 minutes and 48 times within 8 hours. When the average value of these data is higher than the set value of the TWA alarm value, the instrument will simultaneously issue an audible and visual alarm, and can customize the alarm value and type.
5. Alarm value: The instrument records measurement data at regular intervals, recording 15 data points within 15 minutes. When the average value of the 15 data points is higher than the set value of the S alarm value, the instrument simultaneously emits an audible and visual alarm. The alarm value and type can be customized.
