Share real-time gas readings, man-down alerts, and panic alarms with the entire team, so everyone knows who is in danger and why.

Assign the device to a user by name by simply tapping an iAssign badge

Cloud connectivity to ensure users are connected, no matter where they are.

Easily switch between personal 5 gas monitoring and sampling by adding an optional pump.

Quickly alert others of a problem by pressing the panic button.

Why You Need the Ventis® Pro5 5-Gas Monitor 


See more hazards.

Our 5 gas monitor tracks and shares real-time gas readings for up to 5 gases simultaneously. Receive man-down alerts and panic alarms on-site or even in confined spaces, so nearby workers know who is in danger, why, and whether it’s safe to help.

Know what happened.

Get instant text or email alerts with GPS locations and hazard details through iNet Now, so you can respond as quickly as possible.

Dispatch help.

Using iNet Now, you can use real-time safety data to quickly dispatch help exactly where it's needed in an emergency.

Why Use a Connected Monitor

Using gas detectors alone isn’t enough, but connecting monitors can be a challenge on some sites. While other gas detectors offer one mode of connectivity, the Ventis Pro5 offers four—cellular, wi-fi, satellite, and peer-to-peer—so you can connect your workers anytime, anywhere without the hassle of adding infrastructure or IT setup.

Make Ventis Pro5 Maintenance Easy.

Simplify gas detector maintenance by pairing your Ventis Pro5 monitors and DSXi Docking Station with iNet® Exchange—a subscription service that eliminates maintenance by reviewing the performance of a monitor’s sensors, circuit board, microprocessors, and pump every time you dock it. When a monitor needs repairs, we'll simply replace it—no questions asked.

Frequently Asked Questions

Why should I use a 5-gas monitor like the Ventis Pro5?

The Ventis Pro5 is ideal for both personal monitoring and confined space entries thanks to the available pump options. It uses wireless connectivity to add an extra layer of protection and visibility to an already robust multi-gas detector.  

Using a five-gas monitor advances the level of detection, giving you better awareness of the gas hazards around you. The Ventis Pro5 is, of course, capable of detecting even more gases than the Ventis MX4 and has DualSense™ capabilities. 

With the Ventis Pro5, you can set custom, actionable alarms for up to five of the following gases: combustibles/LEL, CI2, CO, CO2, H2S, HCN, NO2, NH3, O2, PH3, SO2 or VOCs. These custom alarm messages make it easy for users to respond appropriately to gas hazards. For example, you can customize the alarm to tell users to “EVACUATE” or “WEAR SCBA” depending on the gas and threshold.

With a man-down alarm, panic button, and extensive connectivity capabilities, you and your workers will be at ease. Wireless connectivity relays gas readings and other worker safety stats to live monitoring software via cellular, wi-fi, or satellite, or to your workers on-site with peer-to-peer. You can then receive real-time alerts that show who needs help, why they need help, and where they’re located. Whether you’re working side by side or far apart, the Ventis Pro5 keeps you and your workers on the same page.

How does the Ventis Pro5 make user assignments so much easier?

The Ventis Pro5 can be enhanced with iAssign Technology to simplify user assignments. Using a pre-programmed iAssign® Tag, the operator can wirelessly enter their name into an instrument simply by tapping the tag to that instrument. Now all data recorded in the instrument will be tagged with the user’s name. This allows users to carry different gas monitors each day while still having a clear data record of who had an instrument when it went into alarm.

What connectivity options are available for the Ventis Pro5?

Adding real-time monitoring to your gas detection program gives you the insights you need to act fast in emergency situations. And if you already have in-plant wi-fi, you can add live monitoring with minimal investment. All you need is a wi-fi connection and a Ventis Pro5 Multi-Gas Monitor to instantly transmit data to iNet® Now Live Monitoring. Add iAssign® Technology, and all live alerts will also include the worker’s name and location.

With this configuration, you can gain total visibility into your operations and receive instant text or email alerts with worker names, locations, and alarm statuses for gas hazards, panic alerts, and man-down situations. This enables you to respond faster and more accurately in an emergency.

How does the Ventis Pro5 share gas readings locally with other monitors?

More and more companies are turning to gas detectors linked by mesh networks to connect workers and share gas readings without costly infrastructure or the hassles of IT setup.

Mesh networks use monitors as nodes to efficiently transmit data. In a mesh network, the data hops from node to node until it reaches its destination. Think of a mesh network as students in a classroom: A student on one side of the room can pass a note to the other side of the room by handing it to a neighbor, who then passes the note to their own neighbor, all the way across the room.

Whereas other networks might fail if one device loses connection, mesh networks can be self-healing. Self-healing mesh networks, such as the ones Industrial Scientific devices use, continue to transmit information across the network even if one node or device disconnects. This means workers will always have a connection to other workers on the network.

Other peer-to-peer wireless networks require IT setup, infrastructure, and a central controller. The beauty of mesh networks—such as LENS® Wireless from Industrial Scientific—is that they offer workers out-of-the-box operability without IT setup.

Mesh networks give safety managers several more benefits over other peer-to-peer wireless technologies, including:

  • Improved Site Communications: Though gas hazards are an immediate issue for the workers exposed to them, they can also threaten others nearby. A mesh network extends worker visibility up to a mile away, so workers are always aware of hazards on-site.
  • Faster Response Times: With a mesh network, there's no need to rely on a central controller or laptop to track peer readings. Every worker with a connected device can see peer readings and alarms, giving them immediate visibility into hazards so they can make smarter, faster, and safer decisions.
  • Safer Emergency Response: Would-be rescuer fatalities are still too common, but mesh networks can help change that. Connected gas monitors can ensure panic and man-down alarms are relayed to other workers in the area so they can see what they are about to encounter.
  • Smarter Decision-Making: Mesh networks ensure that every connected device receives peer alerts and gas readings so workers have all the information they need before making decisions. Informed decisions are smarter decisions that ensure the safety of all workers.

No Infrastructure Required: Wireless networks are only valuable if you can use them. Without the time-consuming site surveys, IT setup, and configuration that other networks require, mesh networks such as LENS Wireless get you up and running quickly and easily.
