Frequently Asked Questions

What is a portable gas detector?

A portable gas detector (also known as a personal gas monitor) is a handheld device used to detect the presence of various hazardous gases in the atmosphere. They are used in a variety of industrial settings to protect workers from exposure to dangerous gases. Portable gas detectors are often battery-powered, easy to wear while you work, and provide real-time gas readings and alarms.

What are the benefits of using a portable gas detector?

Portable gas detectors protect workers from exposure by providing an early warning of the presence of harmful gases, giving the user time to evacuate or take necessary precautions. They are also small and lightweight, making them easy to wear throughout the day. Portable gas detectors can detect a wide range of gases, including combustible gases, toxic gases, and oxygen levels. The sensor flexibility makes them suitable for a variety of applications, from mining and construction to laboratory and research settings. The use of a portable gas detector can help improve workplace safety, increase efficiency, and protect both workers and equipment from harm.

What is the difference between a portable gas monitor and a fixed gas monitor?

The main difference between a portable gas monitor and a fixed gas monitor is their location and purpose. While a portable gas monitor is mobile and typically used by individuals as they work, fixed gas monitors are permanently installed in a specific location. They are designed to continuously monitor gas levels in that location and provide alarms or warnings when gas levels exceed predetermined thresholds. Fixed gas monitors are typically hardwired to a control panel and require professional installation and maintenance.

Portable gas monitors are designed for personal protection and spot-checking gas concentrations, while fixed gas monitors are designed for continuous monitoring of gas levels in a specific location.

What does a personal monitor detect?
A personal gas monitor can detect a wide range of toxic and combustible gases and have flexible configurations to meet your specific safety needs. The sensors we offer include ammonia (NH3), carbon dioxide (CO2), carbon monoxide (CO), chlorine (Cl2), chlorine dioxide (ClO2), hydrogen (H2), hydrogen chloride (HCl), hydrogen cyanide (HCN), hydrogen sulfide (H2S), methane (CH4), nitric oxide (NO), nitrogen dioxide (NO2), oxygen (O2), phosphine (PH3), sulfur dioxide (SO2), and volatile organic compounds (VOCs).
  • Industrial Scientific has definitely made our company safer. Knowing what our personnel are being exposed to and being able to react to those exposures quickly and effectively makes this program worth the investment, which is what it is—an investment in the safety of our employees and contractors.

  • I’m thankful that with Industrial Scientific, we have all of our gas detection information in one central system. We don’t need to use different systems to access historical and live data anymore. Having iNet, we have a reliable system for real-time readings and historical readings for investigations.
