A multi gas tester monitors multiple gases at once to provide a complete picture of your working environment and warn you when harmful chemicals are present. These safety tools help protect construction workers, emergency response teams and industrial manufacturing and maintenance technicians while they are in the field.

Many multi gas tester offer combustible or explosive vapor detection (methane, GPL, hydrocarbons and alcohols), oxygen deficiency, hydrogen sulfide, carbon monoxide, volatile organic compounds (VOCs), and asphyxiant gases like nitrogen oxides and sulfur dioxide. These devices also offer inert gas analysis (CO2, O2) for life science and laboratory applications.

The alarm on a multi-gas monitor can be visual, audible or both and is activated when the sensors reach dangerously high levels. In some cases, the alarm may also vibrate to let users know they need to evacuate the area.

It’s important to maintain a multi-gas monitor and keep it in good condition. First, consult the device’s user manual for instructions on how to set it up. Once the unit is properly configured, you can use it. Keeping the device clean and well-maintained can prolong its lifespan. Regular bump tests and re-calibrations are recommended for best results. Bump tests involve exposing the sensor to a known concentration of calibration gas and adjusting the instrument if the readings are inaccurate.

To perform a bump test, follow the instructions on your device’s user manual to enter the calibration mode and expose the sensor to the calibration gas. You’ll be able to see the sensor readings in real-time and adjust the device.
