Guide for calibration and setting of pump-suction four-in-one portable gas detector

Calibration is an important operation to ensure the detection accuracy and operation reliability of the pump-suction four-in-one portable gas detector. Correct calibration on a regular basis can help the instrument maintain stable and accurate gas measurement performance and ensure that it can provide reliable alarm prompt in dangerous environment.

HIREP pumping four-in-one gas detector can be used to detect a variety of gases, including combustible gas (LEL), oxygen (O), carbon monoxide (CO) and hydrogen sulfide (HS). The equipment is widely used in limited space operation, oil and gas, chemical industry, sewage treatment and industrial safety inspection.

Why do gas detectors need to be calibrated?

In the process of long-term use, factors such as sensor aging, environmental conditions change, temperature change and gas exposure may affect the detection accuracy. Correct calibration can help:

• Improve the accuracy of gas measurement
• Ensure reliable operation of alarm function.
• Extend the service life of the sensor.
• Improve the use safety in dangerous environment.

Calibration and setting steps of gas detector

Before calibration, please ensure that the detector is fully charged, and use certified standard calibration gas according to the detection gas type and instrument requirements.

The basic calibration process includes the following steps:

1. Zero calibration

Zero calibration is to adjust the reference point of the detector in clean air environment, so that the sensor can keep correct zero reading without target gas, and provide accurate reference for subsequent gas detection.

2. Range calibration

Range calibration needs to use standard gas with specified concentration to adjust and verify the response of the sensor, so as to ensure that the measurement results of the detector meet the requirements.

The actual concentration of calibration gas should be consistent with the calibration concentration set by the detector.

3. Alarm parameter setting

Users can set high alarm value and low alarm value according to different working environment and safety requirements. Reasonable alarm parameters can help operators find potential gas hazards in time.
