The Informant 2 Dual Purpose Refrigerant & Combustible Gas Leak Detector

The Informant™2 leak detector allows pinpoint detection of both refrigerant and combustible gas leaks with the same instrument.

Its unique combination of state-of-the-art patented sensor technology, advanced software design and microprocessor controlled circuitry offers you unmatched precision coupled with tremendous speed. It is unquestionably the most sensitive, most reliable, most accurate leak detector on the market today. And the fastest.

Swap sensor tips within seconds and never worry about adjusting sensitivity levels–it’s taken care of automatically–even where high levels of background vapors or refrigerants are present. The refrigerant sensor tip is finely tapered to 0.2 inch diameter–so you can get in between coils and fittings, gaining access to hard to reach areas.

The Informant™2 leak detector features an audible indicator with a mute option coupled with sequential LEDs to monitor increasing concentrations of refrigerant or combustible gases.  

Features and Benefits:

• One instrument—two functions
• Lightweight and ergonomically designed
• Swap sensor tips in seconds
• Microprocessor controlled for accuracy and reliability
• Sensitivity is automatically adjusted
• Sensors are the industry’s most responsive
• Hydrophobic filter prevents moisture contamination
• Optional rubber boot holds MagLite^® flashlight
• Sequential flashing probe tip, dual LED displays and loud tick rate indicates relative concentration levels
• Detects all halogens and scores of hydrocarbon gases
• Response time is two-tenths of one second
• Probe length adjustable from 3" to 20"
• Lifetime warranty available
