TPI 721 Combustible Gas Leak Detector

The TPI 721 Combustible Gas Leak Detector stands as a beacon of efficiency and reliability in detecting potentially hazardous gas leaks. Crafted for ease of use, its ergonomic design allows for effortless operation with just one hand. Equipped with both audio and visual indicators, pinpointing leaks becomes a seamless task, aided further by an adjustable “tic” rate that diminishes background gas interference in contaminated environments. This versatile detector doesn’t just stop at detection; it offers a comprehensive analysis. With the capability to display real ppm, stepped ppm, and %LEL (Lower Explosive Limit), it provides a nuanced understanding of the severity of the situation. Sporting a remarkable 10ppm sensitivity to methane, it ensures even the smallest leaks don’t escape notice.

Whether it’s natural gas, propane, butane, or a range of other combustible gases, the TPI 721 is adept at detecting them all. Its two-line display, complete with a backlight and bargraph, enhances visibility in various conditions. Additionally, users can customize alarm points for heightened safety measures, with the option for earphone use in noisy environments. With approximately 20 hours of continuous use on just two C cell alkaline batteries, this detector ensures prolonged reliability. From its comprehensive leak detection capabilities to its sturdy build, the TPI 721 Combustible Gas Leak Detector emerges as an indispensable tool for safety-conscious professionals across industries.
