They require a bump testing frequency of 6 months or less to ensure performance is consistent. Calibration is only necessary if bump testing indicates the sensor is out of specification. Electrochemical sensors tend to drift over time and require bump testing every 3 to 6 months.

However, most manufacturers recommend performing a bump test at least once a week. This will help ensure that the detector is working properly and will help catch any potential problems early.

Electrochemical sensors tend to drift over time and require bump testing every 3 to 6 months. Calibration is recommended annually or if bump testing indicates an out of spec sensor. Due to the technology of electrochemical sensors, they will deplete over time and more rapidly if exposed to the target gas.

Bump Testing – to check functionality (daily) Bump testing is the only way to ensure the sensors and alarm on your portable gas detector are functioning properly. A bump test involves exposing the detector's sensors to a concentration of gas that is greater than the alarm set points.

A 4 gas monitor detects combustible gas - %LEL, ogygen - O2, carbon monoxide - CO, and hydrogen sulfide - H2S concentrations at the same time. It is the most widely used personal gas monitor in the industry and can be found with sanitation, steel, public works, or confined space workers all over the world.

To do this, put the gas detector into bump test mode, then apply the gas. The gas detector will either cycle through each individual sensor or do them all at once, depending on the gas detector's settings. After the test is complete, the monitor will display results, showing whether it passed or failed the bump test.

Accuracy: Typically listed with a plus or minus 5 percent, it is associated with a confidence interval of 95 percent. This means in 95 out of 100 results; the readings should be within plus or minus 5 percent of the actual gas concentration.

Personal gas monitors are typically worn on the body to detect toxic and combustible gases and protect workers, while process monitors are often handheld and used with a pump and tubing to read the concentrations of toxic or combustible gases during a very specific task.
