Congratulations on the purchase of the AccuTools™ eL-520
Refrigerant Gas Leak Detector, the most technologically
advanced of its kind. The eL-520’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.
Fully SAE J1627 compliant, the eL-520 will detect leaks as small
as 0.1 oz/yr (3g/year) in R12, R22, R134a and other halogen
refrigerant systems.
The eL-520 should not be used on systems that contain
flammable refrigerants such as Propane, Isobutane, etc.
