Frequently Asked Questions

What sensors does the Ventis MX4 4-gas monitor support?
The Ventis MX4 offers sensor and configuration options for a number of industries and applications, making it an efficient choice for both personal gas detection and confined space entries. The Ventis MX4 supports the following gas sensors: LEL (methane), LEL (pentane), CO, H2S, O2, CO/H2 low, SO2, and NO2
How can I use the Ventis MX4 4-gas monitor for confined space pre-entry sampling?
If you need both pumped and non-pumped functionality, buying one monitor that can do both is often more cost effective and reduces the number of monitors your workers carry. The Ventis MX4 4-gas monitor is available in both pumped and non-pumped versions, or can be used with the Ventis Slide-on Pump for pre-entry sampling. With the Ventis Slide-on Pump, you can eliminate the need for extra monitors and transition seamlessly from personal monitoring to confined space entry use. The Ventis Slide-on Pump is ideal for operators who wear their gas monitors primarily for personal protection, but occasionally require a pump for confined space entries. With the Ventis Slide-on Pump, you can: Conveniently sample from up to 50 feet away. Easily attach the pump with no tools. Simplify charging by using the same batteries as Ventis monitors.
What is the warranty on the Ventis MX4 4-gas monitor?

Not all gas detectors are created equal, and warranty coverage reflects that. Shorter warranties indicate that the monitor might have a shorter lifespan. The Ventis MX4 comes with a four-year warranty for the monitor and standard four-gas sensors.

What is the lifespan of the Ventis MX4 4-gas monitor?

If an inexpensive or “disposable” monitor will need to be replaced every year or two, think of the long-term cost when replacing these monitors. With the Ventis MX4, you can upgrade firmware, replace batteries and sensors, and access other service features that extend the monitor’s lifespan.
