Multi Gas Detector – What is it?

A multi gas detector can come in many shapes, sizes and sensor configurations, which can cause some confusion with first time buyers. A multi gas monitor is a portable device designed to detect multiple gases simultaneously. A portable gas detector is usually the last line of defence to alerting operators of dangerous gas leaks. The most common sensor configuration for multi gas monitor is carbon monoxide, hydrogen sulphide, flammable (infrared or pellistor) and oxygen found in the JXCT. This configuration is commonly used for confined space entry such as in the sewer industry, water treatment or tank cleaning.

Multi-gas detectors

However, a multi gas detector is not limited to this standard configuration, our POLI series multi gas detector can have up to 5 sensors, which can be customised with any sensor configuration using its up to 30 sensors. One example sensor configuration is the POLI is Oxygen and CO2, used for industries such as beverage and medical. The POLI can, however, house sensors for more exotic gases, such as VOC’s. VOC sensors may be needed in conjunction with other sensors, such as flam, in applications such as oil and gas or heavy industries. This is due to these being particularly harsh environments with multiple gas hazards that are dangerous to people and plant.

As mentioned, if you are working in a confined space then the JXCT multi gas detector will most likely fit your requirements. Most standard four gas monitors, like the confined space entry example given above, can be ordered online. Where customised sensor configurations are required these may need discussion with the manufacturer as additional maintenance/training may be required.

Always looking for advice

The safety device you purchase provides an early warning of potential gas leaks and ultimately saves your life. When purchasing a monitor, make sure the monitor reflects your application and gas hazard requirements. For example, confined Spaces are such that they are spatially restricted to movement. Therefore, you want your confined space monitor to be lightweight.

You also need to consider if the multi gas detector provides live gas readings and an optional pump module for pre entry checks. This is especially useful for confined spaces. The JXCT multi gas detector is one of the most popular confined space monitors. It is available to order online on our website or you can contact our team.

If you have multiple gas hazards onsite and require a multi gas detector, then you need to make sure that the detector can have the mix of sensors required for your application. In addition you need to check if there are any cross interfering gases that could potentially cause false/incorrect alarms. If in doubt always seek advise the manufacturer. Ask for test data and certificates and discuss your application in detail. Most manufacturers will help with specifying the correct monitor and will provide training. If you are unable to contact the manufacturer, then ensure the distributor is trained by the manufacturer.

Finally, we also supply a range of single gas monitors, for very specific gas hazard applications. This includes ammonia detectors for refrigeration industry or VOC detectors for cleanroom and laboratory applications. Check out our single gas monitors here.
