CALIBRATION GAS

(57 products)

Calibration and bump testing your gas monitor will tell you how reliable they are. It is performed with a traceable concentration of hazardous gas to ensure that the monitor’s sensors are responding accurately and that the alarms function. Once calibrated, the readings displayed on the instrument are reset to match the test gas, indicating that all readings are accurate.

What is calibration gas used for?

Calibration gas is used to bump test and calibrate your gas monitors. The gas is housed in a metal cylinder that through the use of a pressure regulator and tubing will then be exposed to the sensor on the monitor. The amount of gas detected by the monitor should match the contents on the cylinder. This shows that the monitor is working properly by accurately recording the amount of the target gas in the air. The calibration gas in the cylinders must also not expire, as the gas quantity (concentrations) in the container may change over time.

The calibration gas may be a single target gas, such as hydrogen sulfide or carbon monoxide. Others may contain a mixture of gases for instruments having multiple sensor types.

Find the right type of calibration gas or testing equipment for your specific gas monitor based on the type of gases you are trying to detect. Store the calibration gas according to manufacturer recommendations to keep the quantity stable. If the gas is expired, the calibration process may lead to inaccurate results.

Why do gas detectors need to be calibrated?

The sensors on a gas detector will lose accuracy over time due to calibration drift. The sensor produces a reading once exposed to the target gas. This creates an electrochemical reaction that produces a reading on the digital monitor. But the sensors will either become too sensitive or not sensitive enough after exposure to the target gas many times over.

The detector can then be calibrated to ensure the readings are as accurate as possible, so anyone using this equipment can rest assured that they know exactly how much gas is in the air. This will help the team stay safe when occupying areas that contain these hazards.

When should I calibrate my gas detector?

The gas monitor calibration schedule varies based on how and how often you use the equipment. According to OSHA, you should calibrate your instrument before each use to ensure that you have accurate readings. This is especially crucial if the work environment is subject to change or the monitor is older. Responsiveness of monitor sensors can vary depending on workplace conditions. Temperature, humidity, and atmospheric pressure can all affect readings, so it’s important that the sensors are calibrated in environmental conditions as close to the worksite conditions as possible. Store your equipment in a dry, room-temperature location to prevent wear and tear.
