Adding your products to cart

If your chasing down a gas leak or have confined spaces you wish to monitor for potentially hazardous gases, Discount Safety Gear has you covered. Whether you're looking to detect the presence of a single gas or multiple gases, we have an extensive selection of portable gas detectors and area monitoring solutions to meet your needs. All of our detection devices are designed to adapt to a wide range of environments and provide users with real-time detection alerts with visual, audible, and vibrating alarms. When shopping, you'll have the option to chose from a variety of specific models with gas sensor options for Carbon Monoxide (CO), Hydrogen Sulfide (H2S), Oxygen (O2), Ammonia (NH3), Sulfur Dioxide (SO2), Chlorine (CL), Combustible Gas (LEL/LFL), and more!

There are many similarities between single and multi-gas detection devices; however, the most significant difference lies within the number of gases that a device can monitor at one time. Single Gas Detectors are limited to monitoring only one gas, and they're often slightly smaller in size. While Multi-Gas Detectors are suited to simultaneously monitor for up to six hazardous gases at once. Furthermore, multi-gas devices typically have a larger screen for displaying sensor readings to the user. We know that choosing the right gas detection solution can become overwhelming when there are so many options available. Therefore, we recommend that our customers first begin with determining which hazardous gases they wish to monitor for. Then, it will become much easier to chose the correct product that will be best for you.

Explore our gas safety products today and experience great prices on Single Gas Detectors, Multi-Gas Detectors, and gas detection Accessories including replacement sensors, calibration stands, gas cylinders, and more. If you have any questions about our products, don’t hesitate to give us a call today! Our customer service department is standing by ready to assist you at 1-877-734-2458.
