How to calibrate the oxygen gas detector
For the detection of oxygen in the environment, there are many products supplied by Shanghai Zuoqiang Industry, such as oxygen detectors, oxygen detection tubes, dissolved oxygen meters, trace oxygen detectors, etc., such detection products supplied by Shanghai Zuoqiang Industry , can meet our 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 and alarm instrument is a personal portable gas detection and alarm instrument. Its sensor adopts electrochemical sensor with sensitive response. It is suitable for continuous detection of the percentage concentration of oxygen in the ambient air of industrial and mining enterprises. Limit and low limit sound, light and vibration alarms to warn the on-site personnel to evacuate from the dangerous area as soon as possible.
How to calibrate the oxygen detector, let me tell you next:
1. Keep the calibration environment of the gas detector stable and avoid the influence of drastic changes in temperature, humidity, air pressure, and wind speed.
2. The calibration of the detector adopts the standard gas sample comparison calibration method, and the error of each point shall not exceed the specified value of the verification regulations.
3. The flow rate of the standard gas must be strictly in accordance with the requirements of the instructions. If the flow rate is too large or too small, it will affect the test results and cause measurement errors.
4. If the unused enterprise detector is placed for a long time, 3% standard gas should be introduced to activate its catalytic element, and then 1% standard gas should be introduced for adjustment, otherwise the errors of all points are not within the qualified range, resulting in Calibration failed.
5. The standard gas mask of the oxygen detector itself should be selected. If an unreasonable standard gas mask is selected, the value will be unstable and inaccurate.
6. When calibrating the oxygen detection alarm point, the sound and light alarm signal should be observed at the same time. If the alarm cannot be alarmed or the sound and light intensity of the alarm is low, it is a substandard instrument.
