Hello! VPE Korea supplies measurement equipment to many industries. GasTiger 2000 serves both toxic applications and confined-space safety.

We ship dozens of units monthly; hardware failures are rare. Occasionally users press the calibration key by mistake, skewing readings—please coordinate with service before entering calibration mode.

Plant instruments often run in harsh dust. This example came from a power station: the inlet filter was heavily loaded with particulate.

Oxygen read slightly below the 20.9% ambient reference, while CO flickered near 1 ppm before returning to zero—signs the unit needed a proper span check.

We restored accuracy using certified span gas.

For confined-space compliance, verifying all four (or five) target channels against known concentrations is non-negotiable—★ safety first ★.

The 0.8 L/min pump pulled span blends smoothly; readings stabilized after about eight minutes.

Span-cylinder values and the GasTiger display matched within about 99.9%.

Combustible channels display %LEL referenced to methane’s lower explosive limit (5% vol = 100% LEL), so a 50% LEL reading during span checks is expected when using the methane blend supplied.
