Calibration gas is an important component in ensuring the proper performance of your gas monitors. Calibration gas ensures that your gas detector is functioning properly and responding to gas exposures as expected. Gas detection equipment should be bump tested daily and periodically calibrated to ensure the sensors in your gas detector are functioning properly.
When bump testing, the sensors in your gas detectors are briefly exposed to an expected concentration of gas that is greater than the alarm set points. This test verifies that the sensors respond and the instrument alarms function as expected. However the bump test does not check the accuracy of the reading. Learn about our ultra-portable Bump-N-Go.
To verify that your gas detector is accurately reading gas exposures, it should be calibrated monthly. This helps to guard against normal wear and tear, sensor drift and gradual degredation that normally occur over time. A calibration check is performed by exposing the monitor to a certified concentration of gas for a particular time to verify that it provides an accurate reading.

For best results, use only Industrial Scientific calibration equipment for regular instrument calibration and maintenance. All Industrial Scientific calibration cylinders are manufactured to the highest quality standards and include NIST traceable blend techniques, analytical leak testing of every cylinder, certified component concentrations and clearly marked lot numbers and expiration dates. Replacement cylinders are available in a variety of sizes and concentrations for all gases detected by Industrial Scientific instruments.
The calibration gas cylinders supplied by Industrial Scientific Corporation are disposable. These cylinders are DOT – 39 or 2Q rated. This is the same classification used for home aerosol cans. This means that disposal may be performed by relieving the cylinder of any pressure and placing it in your waste disposal container. Check local regulations for compliance.
Some companies are required to dispose of these calibration cylinders as hazardous waste, either by company policies or by state regulations. If your company falls into this category, simply return the empty cylinders to Industrial Scientific.
Bump testing gas detectors before each day’s use is the only way to be sure that the sensors respond to gas. But if your team works on the go, they might not have access to a docking station or calibration gas to check their monitors. By the time they enter hazardous areas, they may not even realize something is wrong with the monitor, until it is too late. Your team needs a solution that goes where the work is, so they can test their gas detectors regardless of location.
