determining the portable gas detector's range
The application of portable gas detection equipment is possible for the detection of dangerous gases, organic volatile organic gases, flammable gases, and single gases. Make accurate early warnings Every day that goes by sees a change in the development of hidden hazard detection technology and an expansion of its use in identifying and removing accident precursors. Miniaturization and automation are its main development focuses in order to achieve long-term monitoring.
The monitoring of environmental protection, interior air quality, hazardous material detection, and industrial safety is all common uses for portable gas detectors. The safety accident prevention technology system works to target and destroy the critical points in the disaster breeding, occurrence, and development processes.
Pay close attention to the used portable gas detector's measuring range:
Any gas detector has a set detection range, and the measurement can only be done within this range, or the result will be far lower than what your surroundings actually contains. Additionally, measuring outside of the measurement range for an extended period of time will harm the sensor, making it impossible to get accurate data when returning to the measurement range.
Pay close attention to the sensor's lifespan in the used gas detector:
Portable gas detectors are not an exception to the rule that gas detectors have a finite lifespan. They will still deteriorate even if they are not used frequently. The photoionization detector generally has a service life of four years or more among portable gas detectors; the LEL sensor is second with a service life of more than three years; the electrochemical specific gas sensor has a relatively short service life, usually between one and two years; and the oxygen sensor has a service life of only about one year.
As a result, you must read the instructions before using and utilize the sensor within the sensor's validity period. If it turns out to be outdated, it must be updated right away.
The detector must be regularly calibrated and tested:
The measurement method used by portable gas detectors is a relative comparison method and is as follows:
1. calibrate the device initially using a standard gas concentration and a zero gas, then save the standard curve in the device;
2. After calculating an accurate gas concentration value, compare the electrical signal produced by the standard concentration with the electrical signal produced by the concentration of the gas being measured.
