The SUPECO HS20004 Trace Internal Dye Refrigerant Leak Detector is an essential tool for anyone working with refrigeration systems. This device is specifically designed to accurately and efficiently identify refrigerant leaks, even those that are hidden from view.
The HS20004 utilizes a non-toxic, non-flammable, and biodegradable dye tracer that is added to the refrigerant. Once a leak is present, the escaping refrigerant carries the dye to the leak location, making it visible for easy detection. The trace dye does not affect the performance of the refrigerant or the system in any way.
This leak detector comes with a user-friendly LCD display that clearly shows the status of the device and the location of the leak. It features a sensitive detection range of 0.05 oz/year for R134a and R1234yf and 0.1 oz/year for R22. The device is also capable of detecting leaks as small as 0.0003 oz/year, ensuring that even the tiniest leaks are identified.
The HS20004 is equipped with a built-in ultraviolet (UV) lamp that illuminates the leaking refrigerant, making it easier to locate the leak. The lamp is located in the nozzle of the handheld detector, allowing for precise and accurate leak detection. The device also has an audible alarm that sounds when a leak is detected, providing an additional visual and audible cue.
The leak detector is designed for easy operation, with a simple push-button design that allows users to turn the device on and off, activate the UV lamp, and view the LCD display. It is also compact and lightweight, making it easy to transport and use in a variety of locations.
The HS20004 Trace Internal Dye Refrigerant Leak Detector is an indispensable tool for anyone working with refrigeration systems. Its high sensitivity, ease of use, and ability to detect even the smallest leaks make it an essential addition to any toolkit. With its user-friendly design and accurate detection capabilities, the HS20004 is sure to save time and money by quickly identifying and repairing refrigerant leaks.
