Need a solid, no-fuss 4 gas monitor you can count on for worksites? The Industrial Scientific Ventis MX4 is pretty much the standard choice for many Kiwi crews, and for good reason. This portable gas detector is built tough to handle daily knocks, giving clear warnings for the critical four gases: Oxygen (O2), combustibles (LEL), CO, and H2S. If your team does regular confined space entry or just needs a reliable detector for everyday safety checks, the Ventis MX4 is often the go-to unit.
It’s straightforward to use, but keeping any Ventis gas detector working right means proper care. We’re the authorised Industrial Scientific service centre here in NZ, so we can help you with everything from routine bump testing and calibration to full servicing, making sure your MX4 is ready when you need it.
