A gas detector detects hazardous or harmful particles in the air by measuring various gases in a given location. These devices are critical for keeping many workers safe, and there are two main types you can employ in the workplace: portable and personal. We help break down the difference between portable vs. personal gas detectors below.

How Do Gas Detectors Work?

Gas detectors use sensors to measure and display the concentration of specific gases in the environment. They function by signaling excessive levels of gases with a succession of audible or visible indications, such as alarms and lights. These devices keep workers from facing exposure to toxic fumes and prevent fires from breaking out.

What Is a Personal Gas Detector?

Personal gas monitors are smaller than portable gas monitors. The devices are usually powered by a single battery and can only detect one gas, although some can detect more. Personal gas detectors are most suited for when your work area is vulnerable to a particular type of hazardous gas, such as CO2.

Personal gas monitors are convenient because workers can attach them to clothing using a clip or ring. They should wear personal gas monitors in the breathing zone, which means they should connect the monitor to a collar, lapel, or shirt pocket with the gas sensor exposed and unrestricted.

What Is a Portable Gas Detector?

Compared to personal gas detectors, portable ones are typically larger and more sophisticated. They can detect and trace multiple types of gas. They’re easy to calibrate and you can recharge or change their batteries without needing to replace the whole unit. They don't have the same resilience or portability as personal gas detectors, but they have a pump that allows you to test gases remotely.

Personal detectors have fewer features and display options. By contrast, portable devices offer a wide range of responses and features and retain a large amount of data.

Which One Do You Choose?

Both personal and portable gas detectors are fundamental instruments for keeping workers safe. The one you choose will depend entirely on your circumstances. You need to know how many gases you need to monitor and how long you need to watch them. You should also know the conditions in which you'll be monitoring and the level of detail required.
