RPB GX4 Intelligent Gas Monitor

Price: £2,155.00
Product Code: CW806
Availability: 1



RPB Safety gas monitor for testing breathing air quality within compressed air breathing air lines. International Standard EN12021 requires that compressed air supplied to air fed respiratory devices must be tested every 3 months, (minimum), by a competent person. This of course includes shot blast helmets, and paint spraying masks.

Made by the same company that manufactures Nova shot blast helmets.

This handy portable kit allows you to comply with legislation, and stay on the right side of HSE inspectors, who are carrying out more frequent, random visits to company premises, and construction sites.

The kit is supplied with the Carbon Monoxide sensor cartridge, which is the most popular. Cartridges for Carbon Dioxide, Oxygen, Water, and Oil Mist can also be purchased, depending on your requirements. The sensors are pre-calibrated, last up to 2 years, and are easy to remove and replace. The machine alerts the user when a cartridge needs replacing.

All housed in a smart, rugged, lightweight case. 

Readings are displayed in real time on the illuminated display, and can also be hooked up via wi-fi to your laptop, tablet, or smartphone. The unit keeps detailed records, updating readings every 5 seconds.

NB. Delivery of this machine is usually approx. 8 working days, as the cartridge has to be calibrated to machine.

Why is it so important ? ....

Asides from the legal compliance aspect, breathing air needs to be thoroughly tested for the presence of substances which may be harmful to the operative. High levels of CO, CO2, mist, and oil can cause the operator to become nauseous, lightheaded, and dizzy. CO, and CO2 don't give off any taste or odour, so they are difficult to detect, until they are at a harmful level. Saturated dessicant, or charcoal type breathing air filters can cause contaminants to build up to dangerously high levels. Regular testing allows you to spot maintenance and servicing issues before they become a problem.
