In view of the flammable and explosive characteristics of hydrogen, once the leakage may cause serious safety accidents, and hydrogen detector as the key equipment of industrial safety monitoring, its accuracy and reliability are very important to prevent hydrogen leakage and ensure the safety of production environment and personnel. Therefore, in order to ensure that the hydrogen detector can continuously provide accurate measurement data, regular calibration operation is essential. Do you know how to calibrate hydrogen detector ? The following is a brief introduction by yiyuntian electronics:

calibration operation of hydrogen detector, the following steps need to be followed:

1. preparation phase

/span>

(1) Select standard gas:

Select a standard gas that is certified to match the gas being tested.The concentration of the standard gas shall match the range and alarm point of the hydrogen detector.

(2) Connecting devices:

Connect the standard gas cylinder to the gas pressure reducing valve and control the gas flow through the glass tube rotameter. Connect the output of the flow meter to the air inlet of the hydrogen detector.

(3) Set parameters:

Set the alarm point and range of the hydrogen detector according to the concentration of the selected standard sample gas.

2. Calibration Phase

(1) Insufflating sample gas:

Open the valve of the standard sample gas cylinder, adjust the gas pressure reducing valve and flow meter, and let the sample gas flow into the hydrogen detector at an appropriate flow rate.

(2) Observations:

Observe whether the hydrogen detector reading is stable and compare it with the concentration of the standard gas. If the reading deviation is large, the calibration parameters of the hydrogen detector need to be adjusted until the reading is accurate.

(3) Record data:

Record the data and parameters during the calibration process, including the concentration of the standard gas, the reading of the flowmeter, the reading of the hydrogen detector, etc.

3. Completion Phase

(1) Shut down the device:

After the calibration is completed, close the valve of the standard gas cylinder and disconnect it from the hydrogen detector.

(2) Organize data:

The data and parameters recorded during the verification process are collated and archived. In addition, in order to ensure the accurate measurement of the hydrogen detector, it is recommended to calibrate once a year. If the use environment is bad or the hydrogen detector alarms frequently, it can also be checked every six months.

In summary, we can see that the calibration operation of the hydrogen detector is A rigorous and meticulous process requires users to strictly follow the manufacturer's calibration guidelines and regulations. Through the correct calibration, the measurement accuracy of the hydrogen detector can be ensured, the reliability of the instrument can be improved, and the relevant regulatory requirements can be met. Therefore, it is recommended that users pay attention to and regularly calibrate when using the hydrogen detector to ensure that it always maintains a good working condition, thereby providing a strong guarantee for industrial safety.
