Gas meter calibration frequency is an essential piece of knowledge in ensuring the safety of workers or a building, as well as the integrity and accuracy of your equipment. The calibration of gas monitors is a safety procedure that should be routinely executed to ensure its correct function, extend the lifespan of the unit and verify its ability to provide lifesaving readings and alarms.
Servicing all brands and models of gas detectors, Newcastle Safety Servicing can calibrate, and repair portable or fixed gas monitors and provide professional advice on gas detector calibration frequency with our gas calibration service. As such, we’ve provided this detailed guide on gas detector calibration frequency to aid those who may be a little lost on how often they should have their equipment inspected, serviced and calibrated.
Gas monitors are sensitive instruments which detect the levels of various gases in a target area. Portable gas monitors can be implemented as a piece of PPE to ensure safe working spaces for an individual. Fixed units can test for multiple gases and installed in commercial, industrial and residential settings to test for multiple dangerous gases.
When asking yourself “how often should I calibrate gas detectors?”, it is important to consider the applications the unit is being applied in, the amount of gasses it is being exposed to, how often you are using it and if it has become vulnerable to any significant damage.
Gas detectors are often reliable, however, just like any other piece of equipment, the internal components of a gas monitor are prone to wear and tear, which will affect gas monitor reactions and readings. The lifespan of a specific meter is also dependent on the amount of gas vapors they are exposed to, so some will last longer than others depending on their application.
Regular maintenance, inspection and gas meter calibration frequency can extend the working life of your instrument and ensure it is consistently producing accurate and valid readings. Your calibration schedule should be routine and regular, to ensure the correct and accurate function of your instruments and the safety of workers or individuals who depend on them to stay safe. Depending on your manufacturers guidelines and industry of operation there may be specific considerations for your calibration schedule.
When looking at calibration and gas meter calibration frequency there are two options. To start with, let’s take a look at a bump test.
A bump test is a quick, functional test in which the correct operation of the alarm and sensor can be verified using a predetermined concentration of gas. As this test is easier and quicker than a full calibration, it should be carried out on a regular basis. It is recommended that portable gas detection units have a bump test conducted prior to each use.
The amount of gas used within a bump test should be high enough to trigger the units alarm to ensure it is functioning correctly and the unit is targeting the desired gas. As the concentration of gas is known, you will be able to determine if the measurement tolerance of the device is in accordance with the manufacturer’s guidelines (just remember to ‘zero’ the device in a fresh air environment before testing to give an accurate reading). If it is within tolerance and passes the test, you can be confident that your device is fit for your use.
A bump test should also be done after the device has experienced any potential damage or exposure to harsh conditions. Routine bump testing can also reduce your gas meter calibration frequency to somewhere between every 3-6 months; without this, more frequent calibration will be required.
If the unit does not show a reading within the acceptable range from the bump test, a full calibration must be performed. This procedure is to be conducted by a trained and authorised calibration professional. At Newcastle Safety Servicing we are fully qualified to calibrate, issue a certificate and log the calibration into the unit. We can also provide on-site calibration services so you can reduce the downtime for yourself and that of your equipment.
The calibration process adjusts the unit’s measurement outputs to coincide with a known concentration of gas – this is a certified amount per industry, or manufacturing guidelines. The technician conducting the calibration will also be able to inspect the internal components of the instrument and identify if the sensor has any contamination on it which may be interfering with the unit’s operation. Calibration practices and protocols should always be aligned with manufacturers guidelines to ensure the accuracy and validity of the calibration and certification.
