TT-100 Semiconductor Leak Detector

The TT-100 Semiconductor Leak Detector is a high-precision tool designed for detecting all CFC, HCFC, HFC, and HFO refrigerants, including R-1234yf, R-134a, R-410A, R-22, R-407C, R-507, R-12, and R-404C. Featuring a solid electrolyte semiconductor sensor for long life and stable performance, it provides exceptional sensitivity with 0.015 oz/yr for R1234yf and 0.05 oz/yr for R134a. The device includes a 7-level digital leak size display, audio mute mode, three sensitivity levels, and a low battery indicator. CE-certified and powered by 4 AA alkaline batteries, the TT-100 comes with a 2-year warranty including the sensor, making it a reliable tool for professional HVAC and refrigeration maintenance.Complementing the leak detector, the Digital Manifold Gauge features two temperature probe clamps, an extra-large LCD screen, and three-color fluoridated tubes for clear readings. It offers automatic calculation of superheat and subcooling, A2L flammable refrigerant warnings, and supports 87 refrigerant types with continuous updates. The gauge can measure pressures from -14.5 to 500 psi / -14.5 to 800 psi with multiple units (psi, bar, kg/cm², inHg, kPa, MPa), overload capacity of 2× range, and includes magnetic hooks for convenient storage. Powered by 3 AAA batteries, this multifunctional digital manifold is ideal for accurate diagnostics, safe operation, and efficient HVAC service work.
