eL-720 Carbon Dioxide Gas Leak Detector

SKU eL-720 Category


The AccuTools® eL-720 Carbon Dioxide Gas Leak Detector is the most technologically advanced of its kind. The fully automatic eL-720’s low power requirements, small size, and high sensitivity combine to create a tool which is easy to handle and ultra effective at locating even the most difficult-to-find leaks. The infrared sensor will make false alarms a thing of the past when finding even the smallest leaks in R744 systems and CO2 specific applications.Whether servicing commercial refrigeration systems, finding a leak in a restaurant soda machine, or pinpointing a minute leak in a room filled with CO2 at a bulk CO2 manufacturing facility, the eL-720 stands alone when it comes to ease of use, quality of response, and high sensitivity levels with no false alarms.
