Pump Suction 4-in-1 Portable Gas Detector Zero Calibration Tutorial

The pump suction 4-in-1 portable gas detector zero calibration process is an important step to ensure accurate gas measurement and reliable safety monitoring. In this video, HIREP demonstrates how to perform zero calibration on a portable multi-gas detector for LEL, O₂, CO, and H₂S detection.

Regular zero calibration helps maintain sensor accuracy, improve detection reliability, and ensure the gas detector provides correct readings in critical industrial environments. Proper calibration is widely required in applications such as oil and gas, petrochemical, chemical plants, mining, confined space operations, and industrial safety inspections.

This tutorial covers the basic zero calibration procedure, including preparation before calibration, entering the calibration mode, and completing the zero adjustment process. By following the correct calibration steps, users can extend sensor service life and maintain stable gas detection performance.
