GasTiger2000 Equipment Maintenance & Standard Gas Calibration Case

The GasTiger2000 gas detector is used not only for measuring toxic and hazardous gases, but also for safety in confined spaces across a wide range of industrial sites.

Dozens of these detectors are sold every month, and after-sales service for device failures is rarely needed. However, since this is gas measurement equipment, the reading can occasionally be thrown off if the calibration button is pressed by accident.

* When using gas measurement equipment, please consult a specialist before pressing the calibration button. *

As this is safety equipment used in plant environments, it often measures gas under harsh conditions. The unit shown here was in use at a power plant site, where dust had accumulated heavily near the air intake.

The O2 (oxygen) concentration was measuring lower than the standard atmospheric level of 20.9%. A CO (carbon monoxide) reading of about 1 ppm was detected, but the value dropped back to 0 ppm within a few seconds.

Standard gas is used to calibrate the measured values accurately.

For safety in confined spaces, measuring all four gases against the "standard gas reference concentration" is essential.

★ Safety comes first ★

With a very strong pump (0.8 L/min), the GasTiger2000 draws in the standard gas to calibrate its readings. The results can be checked after about 8 minutes.

The standard gas concentration value and the GasTiger2000's measured value matched at 99.9%!

* These standard gas calibration figures show just how accurate the GasTiger2000 model is. *

For Ex (combustible gas), the GasTiger2000 displays readings in LEL units. Since the explosive lower limit of 5% (based on methane/CH4) is set as 100% LEL, a reading of 50% is the correct value.

This is the GasTiger2000 model drawing in ambient air. We provide inspection, maintenance, and calibration services for gas measurement equipment, and we can also handle KOLAS certification on your behalf.

That concludes this case on the GasTiger2000's confined-space safety equipment and calibration.

Frequently Asked Questions (FAQ)

Q1. Should anyone be able to press the calibration button on the GasTiger2000?

No. The calibration button on gas measurement equipment should only be pressed after consulting a specialist, since pressing it accidentally can throw off the readings.

Q2. How long does standard gas calibration take?

The unit draws in standard gas using a strong pump (0.8 L/min), and the calibrated reading can be checked after about 8 minutes.

Q3. How should Ex (combustible gas) readings be interpreted?

The GasTiger2000 displays readings in LEL units. Since the explosive lower limit of 5% (based on methane/CH4) is set as 100% LEL, a reading of 50% is the correct value.

Q4. How accurate is the calibration?

The standard gas concentration value and the GasTiger2000's measured value were confirmed to match at 99.9%.

Q5. Is KOLAS certification support available?

Yes. Inspection, maintenance, and calibration services for gas measurement equipment are supported, along with KOLAS certification processing on your behalf.
