Leak detector for R1234yf Mastercool 55800 The high-quality Mastercool 55800 leak detector is specially designed to detect R1234yf, R407C, flammable gases, hydrogen and all common refrigerants (CFCs, HCFCs, HFCs). It uses a new metal oxide gas sensor to detect chlorofluorocarbons (CFCs) and mixtures. Due to its high sensitivity and fast response behaviour, even tiny quantities of CFCs can be effectively detected. An integrated powerful microprocessor automatically selects the optimum operating conditions for the sensor to ensure optimal performance. Technical data: Sensitivity levels: HIGH ≥ 1.5 g/year MEDIUM ≥ 7 g/year LOW ≥ 14 g/year Intelligent sensor design Flexible 40 M test probe Progressive LCD display with vertical bars Recognises all refrigerants (CFC, HCFC, HFC) Sensor service life: 2000 hours Working temperature range: -17 - 60 °C (0 - 140 °F) Power: 2 D batteries Battery life: 60 pcs Weight: 0.82 kg The "Super Sensitive FUNCTION" allows the device to perform further sensitisation beyond the standard settings for locating small leaks with gases such as R1234yf and R407C. The LCD display has various modes such as "WAIT Mode", "READY Mode", "INT Mode", as well as displays for the battery status, sensitivity ranges and error messages.

testo 316-4 Set 1 – Leak detector for CFCs, HFCs, F-gases, H₂ and formier gas The testo 316-4 Set 1 is a versatile leak detector for all common refrigerants (CFCs, HFCs, F-gases), hydrogen (H₂) and formier gas. The scope of delivery includes the KM sensor head, a robust case, a mains adaptor and earphones – ensuring you are fully equipped for fast and reliable leak detection. An all-rounder for leak detection: a fast and reliable leak detector for all common refrigerants as well as H₂ and forming gas. Practical sensor technology: The sensor is continuously monitored and displays any malfunctions or contamination on the screen – meaning a test leak is no longer necessary. If the sensor becomes dirty, it can be easily cleaned and put back into use straight away. Thanks to the flexible gooseneck, the sensor can be positioned close to the pipework or at the measurement point. High sensitivity: Very high sensitivity of < 3 g/a in accordance with EN 14624 enables the reliable detection of even the smallest leaks. The trail indicator function displays the maximum leak rate and makes it easier to locate the leak. Reliable warning functions: The display changes from green to red in the event of a leak. An audible signal also alerts the user to detected leaks. With the earphones supplied, the leak detector can also be used in noisy environments. Option for ammonia (NH₃): For refrigeration systems using ammonia, the testo 316-4 (Set 1) can be upgraded with the separately available ammonia (NH₃) sensor head. Alternatively, the testo 316-4 Set 2 is available specifically for NH₃. Technical data Detectable media: R134a, R22, R404A, H₂ and all common refrigerants such as CFCs, HFCs, F-gases; NH₃ with separate sensor head Sensitivity: < 3 g/a (in accordance with EN 14624:2012) Leak alarm: visual and audible alarm Alarm function: visual (display colour change), audible (audible signal, headphones can be used) Response time: < 1 s Start-up time: < 50 s (0 ... +50 °C) Operating temperature: -20 to +50 °C Storage temperature: -25 to +70 °C Operating humidity: 20 to 80 % RH Dimensions (unit): 190 x 57 x 42 mm Weight: approx. 348 g Gooseneck length: 370 mm Battery type: 1 battery pack (6-cell NiMH) Battery life: approx. 6 hours (continuous operation) Standards: EN 14624:2012 Contents testo 316-4 leak detector KM sensor head Carrying case Mains power supply Earphones
