Gas Leak Tester Selection and Calibration for CKD Assembly Lines

The gas leak tester is the most important piece of equipment on any gas stove assembly line. It is the final safety gate — every stove must pass it before it leaves your factory. Choosing the right tester, and keeping it calibrated, is what separates a responsible manufacturer from a risky one.

What to Look For in a Leak Tester

• Pressure range — the tester must cover the working pressure of the stoves you assemble, with margin for the test pressure you will apply.
• Hold time control — a good tester holds a fixed test pressure for a set duration, so a slow leak is not missed.
• Accuracy and sensitivity — it must detect the smallest leak that could become dangerous, not just obvious ones.
• Automated pass/fail — an automatic pass/fail readout removes human judgment error and speeds the line.

Pressure and Hold Time Matter

The test is only meaningful if the pressure and hold time are set correctly. Too little pressure or too short a hold lets leaks slip through; too much pressure can damage the system. We guide CKD partners on the correct test parameters for each stove model.

Calibration Is Not Optional

A leak tester that drifts out of calibration gives false pass results — the worst possible failure. Establish a calibration schedule, keep records, and verify the tester against a known reference regularly. Calibration is a quality-system requirement, not a suggestion.
