Negosentro.com | 3 Things You Should Know About Calibration Gases | In some cases, workplaces with highly toxic gases could cause serious health risks for workers. That is why gas detectors determine if the gas has been eradicated or is safe for workers to work while it is present in the air. Even with personal protective equipment, the dangerous gas must be eliminated from the worksite.

For the gas detector to work correctly, it needs to be calibrated by using a calibration gas cylinder filled with a particular gas that assists the detector. If you are new to using gas detectors, you have to learn that the calibration gas is one component that rarely gets attention. You must understand what it is if you want to use your gas detector effectively.

What Are They?

Calibration gases are utilised to calibrate different types of gas detectors and ensure that they produce accurate results. The only way to test out the gas detector’s accuracy is by testing it with a well-known gas concentration, which is the calibration gas. When you expose the detector to a specific gas concentration, you can quickly determine whether it responds accurately or shows inaccurate results.

When to Use Calibration Gases

To run the accuracy tests, gas detectors will always need a calibration gas cylinder filled with a specific gas. Calibration gases are always critical whenever you need to run a calibration test or when a full calibration is being carried out. While there are no certain rules as to when you need to do the calibration tests on a device, you can learn several practices you need to follow when doing so.

  • Before using portable direct reading gas monitors, you need to carry out a functional or full calibration test every day.
  • You need to do calibration most of the time if the environmental circumstances could negatively affect the detector’s performance. Some ecological conditions that could affect it include high gas concentrations, mechanical stress, sensor poisons, and significant temperature changes.
  • You need to run a full calibration test each time the device fails the functional test.

If you see even a slight miscalculation of the gas detector, you must do a full calibration test right away. Exposing your detector to a specific concentration calibration gas will confirm its reading accuracy and proper alarm functioning. Note that workers who do not conduct the functional or complete calibration tests on detectors are susceptible to hefty fines and penalties.

Best Tips in Testing Calibration Gas

It will not matter if you are very careful in testing the calibration gas because many factors go into the testing. When dealing with dangerous gases, it can cause a tremendous amount of stress for anyone, which results in losing their focus. However, you can find some tips that can help you do the calibration gas testing smoothly.

  • Zero in your device in fresh air
  • A daily calibration check is a must before using the gas detector.
  • Full calibrations are required each month.
  • Check the instrument’s values and ensure the sensor readings correlate with the gas concentration listed on the cylinder label.
  • Make use of the right fittings and regulators to grant calibration gas to the gas detector.

Hopefully, the things mentioned above can help you better understand calibration gases and conduct the proper gas detection tests. You should also get your gas calibration cylinders to provide customised gases to ensure your detector runs perfectly.
