Toxic gases are one of the number one risks to employees working in industrial environments and yet some employers are not monitoring the breathing air their workers are using every day. Put the safety of yourself and your employees first with the GX4 Gas Monitor from RPB – an intelligent monitoring system which can detect up to four gases simultaneously.

Some toxic gases like carbon monoxide are completely invisible to the human senses but high level exposure can kill in a matter of minutes and even low level exposure can cause serious illness and long term health concerns. Early symptoms are often mistaken for flu, headaches or tiredness and are frequently ignored.

The GX4 can be easily mounted to the RPB Radex Airline Filter or to the wall and constantly monitors air supply for up to four different gases. The unit uses four pre-calibrated gas sensor cartridges that last for up to two years and can be easily removed and replaced as required. It is fitted with a 103 DBA staccato alarm and can also be connected to other external alarms or automatic shut off systems to make sure that workers are alerted if gases are approaching unsafe levels.

Readings are displayed in real time on the illuminated display and the unit also has a built in WIFI hotspot so it can be accessed via a laptop, tablet, phone or network. The unit keeps detailed records, logging data every five seconds which is useful for inspectors. It also keeps logs of any alarms that go off so that if it is ignored or silenced you’ll still be able to see when it was triggered. It also monitors each gas cartridge and alerts the user when a replacement is needed.
