Calibration gas is used to ensure gas meters and gas detectors are working properly. These pieces of equipment are essential for testing gas levels and maintaining optimal performance in hazardous job sites. These meters, detectors, and additional instruments require regular calibration to ensure accurate readings and avoid potentially catastrophic situations. Calibration means to correlate the…

Calibration Gas is a reference gas or gas mixture used as a standard when calibrating gas analysis instruments such as a gas detector. A gas detector is used to determine if there are certain gases in the air. The calibration gas, a known specific concentration of the test gas, can then be used to as a reference to determine if the gas amounts in the surrounding area are less or more than this…

 Facts about H2S aka “sour gas”  H2S is heavier than air, accumulates in low-lying areas, and may travel along the ground.   The danger with H2S lies in the fact that at higher concentrations, it does not obtain a noticeable odor. At low concentrations the smell is often is described as “rotten eggs”    When unprotected workers, rescue workers, etc. are exposed to high concentrations…

Gas Detector Tubes: Glass tubes that have graduating scales printed on them. You can directly read the concentrations of the gas or vapor to be measured based on the color change of the scale. The color change is achieved because the tube contains a detaching reagent that is sensitive to the target substance. No color chart is needed. There are different variations of the Gas Detector Tube: Most…

A gas detector tube is a glass tube that is filled with a reagent that creates a color change when exposed to the gas that is being tested. The detector tube will indicate the concentration of gas by the printed calibration scale on the tube. They are typically used with a hand pump that will pull any gas that is in the air into the tube. Gas detector tubes are typically used to determine if…

In order to make sure that a gas detector instrument will detect gases in the air accurately, a calibration gas of a known concentration must be used to ensure that the gas detector is responding accurately to the amount of gas it is measuring. Although a gas detector may have been calibrated in the past, many outside factors can affect the calibration over time and therefore the detector needs to…

Calibration Gas is a certified gas mixture, also referred to as span gas. The gas (known concentration) is used to ensure gas detectors or meters are working properly. Gas detectors or meters are used to check gas levels in areas that are considered hazardous. The detectors or meters require calibration on a routine basis. By introducing a known concentration of gas to the detector or meter's…
