As we all know, the performance of gas detectors tends to gradually decrease with the passage of time, changes in use conditions, and aging of internal components. Therefore, in order to ensure that the gas detector can continuously and accurately provide monitoring data, Regular error calibration is an essential link. In these 1 key processes, sufficient preparation before calibration is undoubtedly the premise to ensure accurate and reliable calibration results. Do you know what preparations need to be made before gas detector error calibration? The following Eranntex electronic editor introduces you:

Before the error calibration of the gas detector, the following preparations need to be made:

(1) Make sure the instrument is off:

Before calibration, place the gas detector on a stable surface and make sure it is closed to avoid unnecessary errors during preparation.

(2) Check the instrument status:

Check whether the appearance of the gas detector is intact, whether the display is clear, whether the keys are sensitive, etc., to ensure that the instrument is in good working condition.

2. standard gas preparation

strong> (1) Select the correct standard gas:

Prepare the corresponding standard gas according to the gas type to be calibrated. The concentration of standard gas should be accurate and reliable, and meet the requirements of relevant standards or codes.

(2) Ensure that the standard gas expiration date:

When using standard gas, pay attention to its validity period to avoid using expired standard gas to cause inaccurate calibration results of gas detector.

(1) Keep the environment clean:

When the gas detector is calibrated, a laboratory or office environment with good air quality should be selected to avoid the impact of dust, oil and other pollutants on the calibration results.

(2) Control environmental conditions:

Keep the error calibration environment of the gas detector stable and avoid drastic changes in temperature, humidity, air pressure, wind speed, etc., otherwise these factors may affect the accuracy of the calibration results.
