Reliable Gas Detection You Need

The Ventis® MX4 is a 4-gas monitor designed to be rugged yet lightweight and easy to wear. This multi-gas detector eliminates the need for extra monitors by transitioning seamlessly from personal monitoring to confined space entry with a slide-on pump.

Flexibility to Fit Your Gas Detection Needs

Whether you’re performing daily confined space entries, wearing the instrument for personal gas detection, or anywhere in between, there’s a Ventis MX4 configuration that’s right for you.

Monitor up to four of these gases: LEL (methane), LEL (pentane), CO, H2S, O2, CO/H2 low, SO2, NO2.

Enjoy uninterrupted runtime with optional batteries that run for 20-hours on a single charge.

Personalize the monitor to your needs by selecting alarm thresholds and setting latch alarms.
