Meets and exceeds J2791 (R134a), J2913 (R1234yf) and EN 14624 At the heart of this leak detector is a new low power metal oxide gas sensor with superior performance properties such as lower current consumption and sensor longevity. The sensor is characterized by high sensitivity and fast response upon detecting the presence of extremely small levels of chlorofluorocarbon gases. F Powerful microprocessor was integrated into the design that automatically selects the best operating condition for the sensor to ensure optimum performance throughout the life of the sensor. Sensing Element: Heated Tin Oxide Element Sensor Life: 2000 hours Refrigerants: Detects all refrigerants (HFC, CFC, HCFC, and blends). Sensitivity Levels: HIGH : 0.15 oz/yr (4 g/yr), MEDIUM: 0.25 oz/yr (7 g/yr), LOW: 0.50 oz/yr (14g/yr) Response Time: less than 1 second Battery: 2 Ÿ??CŸ?� Alkaline 6000 mAh batteries Operating Temperature Range: 0?F to 120?F Probe: Intelligent tip, with environment sensing element to eliminate the potential of false alarms. Flexible 15.5 inch probe length for difficult to reach locations. Display: Six vertical LEDŸ??s enabled selectively (red, yellow or green) to display the following information to the user such as: The relative signal level of the detected leak The selected sensitivity range (low/medium or high) of the unit The gain of the unit (low gain or high gain ) Diagnostic information : low battery, interference/wait, contaminated atmosphere readiness of the unit or fault conditions of the unit Keypad Controls: ON/OFF button (push-on/push-off) Volume/Mute button (high, low or mute) Sensitivity button for High, Medium and Low sensitivity level selection Peak button when multiple leaks are suspected (push enable/disable)
