[Tweet](https://twitter.com/share) Does your site have the equipment necessary to keep workers safe and get the job done successfully? Gas detectors are important instruments for detecting toxic or combustible substances before they can pose a risk to the health and safety of workers. There are many different types of gas detectors and monitors, and they each offer different functionalities. It is important to understand what a portable gas detector is, how it works, why it is important, and how to choose one for your facility.  ## What is a mobile gas detector? A mobile gas detector is a unit that houses a sensor to measure the concentration of certain gases in the air. The sensor is a scale and reference point that produces and transmits a measurable electric current when specific gas enters the atmosphere. Gas detectors and monitors are available as single or multi-gas monitors. Mobile Detectors are distinct from other types of detectors because they are solar-powered. This allows the device to work even in the event of a process shutdown. Electricity is not required for mobile gas detectors to operate.  ## How does the TechStar mobile gas detection system work? The TechStar mobile gas detector is a solar-powered, advanced gas detection system that is fully customizable. The detection system consists of two sensors that monitor the concentration of gas in the air and transmit visual and audible alerts when problematic levels are detected. The transmitter has a multi-lingual display that is easy to read and easy to navigate with a unique touch-screen interface. TechStar’s mobile gas detection systems eliminate the need for workers to disconnect power before changing the sensor, remembering how to calibrate the device, and wondering if the device is working properly.  ## Advantages of Using MSA Mobile Gas Detectors TechStar’smobile gas detector is equipped with advanced technologies including Diffusion Supervision, Organic LED (OLED) display, SafeSwap, Bluetooth, and TruCal. Together these technologies increase the accuracy, reliability, and usability of the device. Diffusion Supervision warns if the sensor inlet becomes blocked and unable to detect gas. SafeSwap enables safe and quick replacement of gas sensors without turning off the instrument. Bluetooth wireless technology allows the mobile device to act as an HMI screen and controller and connect to an app that provides real-time information on a user’s smartphone.  MSA’s breakthrough TruCal patented extended calibration technology corrects sensor drift and extends calibration periods for XCell Hydrogen Sulfide (H2S) and Carbon Monoxide (CO) gas sensors using Adaptive Environmental Compensation (AEC) algorithms.  ## Tips for Choosing a Mobile Gas Detector It is critical that you find the right mobile gas detector for your site. With so many different options available on the market, it can be difficult to know what is most suitable for your application. The best mobile gas detectors are equipped with solar panels so you never have to worry about the viability of batteries or the availability of electricity. In the event of a problem, disaster, or system shutdown, the mobile gas detector needs to be available and ready to deploy. Even if your power shuts down, there is still the potential for dangerous gas to be present. The best mobile gas detectors utilize dual sensors to ensure maximum coverage and detection capabilities. Furthermore, the sensors need to be replaceable without interrupting the instrument. Connected technologies like Bluetooth and cloud compatibility allow professionals to monitor and control the detector from a safe distance.  ### [TechStar’s Mobile Gas Detection System](https://info.techstar.com/mobile-gas-detection) TechStar’s Mobile Gas Detection System can be easily placed at a moment’s notice.  The mobile system utilizes the advanced technology of the MSA Ultima X5000 Gas Monitor, is solar powered, easy to store when not in use, and is fully customizable to meet your needs. The advanced technologies are complemented by the portable design that allows workers to move the gas detection system throughout a site and place it where it is needed most. The TruCal technology ensures that the calibration standards are maximized and the device is reliable, accurate, and secure.  TechStar is your manufacturing representative for instrumentation, automation, and analytical products, service, and training, including MSA mobile gas detectors.
