The Ventis MX4 multi-gas monitor from Industrial Scientific detects from one to four gases with a wide range of sensor options. Draw samples from up to 100 feet with an optional, integrated sampling pump for confined spaces, or take advantage of the extended-range battery for up to 20 hours without the pump. A safety orange overmold increases visibility and safety in the field. If the gas detection needs are temporary, rental options are ideal for shutdown or turnaround applications. It is docking station compatible and iNet ready. 800/338-3287; www.indsci.com.
