TESTO 316-4 - ELECTRONIC REFRIGERANT DETECTOR 0563 3164 WITH CALIBRATION PROTOCOL
The TESTO 316-4 is a professional leak detector designed for detecting refrigerant leaks, including CFC, HFC, HCFC, and hydrogen (H₂). With a high sensitivity of less than 3 g/year, it can detect even the smallest leaks, making it an essential tool for service work and diagnostic tasks on refrigeration systems.
The device is equipped with a flexible gooseneck probe that allows precise access to hard-to-reach areas, such as pipes and fittings. A useful feature is the option to connect headphones, enabling convenient and safe operation even in noisy environments – the user will hear the alarm signal regardless of ambient noise levels.
The detector features both visual and acoustic alarms: when a leak is detected, the display changes color (for example, from green to red), and the device emits an audible signal. The installed sensor is continuously monitored – the system alerts the user to any malfunctions, contamination, or sensor errors, minimizing the risk of inaccurate measurements.
The kit includes all necessary accessories: a sensor head, power unit, headphones, and a robust transport case. The device weighs approximately 348 g and is designed to operate in temperatures ranging from -20 °C to +50 °C, ensuring reliable performance in demanding working conditions.
Thanks to its comprehensive design, the TESTO 316-4 is a dependable tool for service technicians, installers, and HVAC professionals. It combines precise measurements, intuitive operation, and durable construction, allowing users to quickly detect and locate leaks while minimizing refrigerant loss.
