To calibrate an oxygen gas detector, follow these steps
For the detection of oxygen in the environment, there are many products supplied by Shanghai Left Wall Industry, such as oxygen detectors, oxygen detection tubes, dissolved oxygen meters, trace oxygen detectors, etc. These detection products provided by Shanghai Left Wall Industry can meet the corresponding detection of oxygen content in various environments. This oxygen detector is one of them, mainly used to detect the concentration of oxygen in ordinary environments.
Oxygen detection alarm device is a personal portable gas detection alarm device. Its sensors use electrochemical sensors, which are sensitive and suitable for continuous detection of the percentage concentration of oxygen in the air of industrial and mining enterprises. When the environmental concentration is too high, it will give high and low limit sound, light, and vibration alarms to warn on-site personnel to evacuate the dangerous area as soon as possible.
How to calibrate an oxygen detector? Next, let me explain to you:
1. Maintain a stable calibration environment for gas detectors and avoid the impact of drastic changes in temperature, humidity, air pressure, wind speed, etc.
2. The calibration of the detector adopts the standard gas sample comparison calibration method, and the error at each point shall not exceed the specified value in the verification regulations.
3. The flow rate of standard gas must be strictly in accordance with the instructions. Excessive or insufficient flow rate can affect the detection results and cause measurement errors.
4. If an unused enterprise detector is left unused for a long time, it should first activate its catalytic element with 3% standard gas, and then adjust it with 1% standard gas. Otherwise, the error at each point is not within the qualified range, resulting in calibration failure.
5. The standard gas hood of the oxygen detector itself should be used. If an unreasonable standard gas hood is used, numerical instability and inaccuracy may occur.
6. When calibrating the oxygen detection alarm point, it is necessary to simultaneously observe the sound and light alarm signal. Instruments that cannot alarm or have low sound and light intensity are considered unqualified.
