Description
  • High-precision refrigerant leak detection The NF-604 halogen leak detector offers accurate detection with a range of 0–1000 PPM and a resolution of 1 PPM, ensuring reliable performance for identifying refrigerant leaks in HVAC systems.
  • Clear color LCD display for real-time monitoring Equipped with a color screen, the device provides clear visual feedback, displaying real-time gas concentration levels and alarm status for easy interpretation during inspections.
  • Multi-mode alarm system for enhanced safety Features beep, vibration, and display alarms to alert users to gas leaks. Supports both high limit and low limit alarm settings for customizable detection thresholds.
  • Long working time with efficient power management Powered by 4 x 1.5V AAA batteries , the detector operates for over 6 hours and includes auto-shutdown options at 15, 30, or 60 minutes to conserve battery life.
  • Fast warm-up and wide operating temperature range With a 30-second warm-up time, the device is ready for use quickly. It functions reliably in temperatures from -10°C to 50°C  for versatile indoor and outdoor applications.

    Product Function:

    1. Traditional corona sensor with updated analogue circuit, fast triggers on R11, R22, R134a, R404a, R417A and all halogenated 1. 1.Traditional corona sensor with updated analogue circuit, fast triggers on R11, R22, R134a, R404a, R417A and all halogenated refrigerants including CFCS, HCFCS, HFCS and blends;  

    2. 30s preheating time, instantaneous response;

    3. A flexible probe around 9.44 inches allows detections in difficult and hard-to-reach areas;

    4. Direct status indication with audible & visual leakage alarm indicators;

    5. With 1 PPM resolution, our detector is a reliable 'freon leak detector';

    6. Easily help you to locate where the leakage is. Once leaking gas is detected, the beep frequency will increase. The more gas leaked, the quickly the buzzer beeps, at the same time, the LCD screen displays the leakage level.

    7. Battery by 4 AAA batteries (Not included)

    Please Note:

    1. In open areas with good ventilation, even large leaks are difficult to detect because the leaked refrigerant dissipates quickly. In this case, the area where the leak may occur should be blocked.

    2. When there are multiple leaks, the leaks with more serious leaks should be found first. After the large leaks are found, the small leaks will be easier to find.
