The manifold gauge set has the double pressure test, dual temperature test, digital readout, multi-unit switching (kPa, Mpa, bar, inHg, PSI or C, F ), and multi-mode function.
• Pressure Leak Test The manifold gauge calculates the pressure difference between the initial test pressure and the second test pressure to determine if the refrigerant is leaking. The digital HVAC manifold gauge set is specially used for the installation, testing and maintenance of refrigeration equipment such as air conditioners, refrigerators, and cold storage.
• Ball Valve Type Switch & LCD Display & Hook Design The HVAC refrigerant gauge adopts high-strength engineering plastics and an anti-skid design, the whole gauge is sturdy and comfortable to hold. Large-size LCD display, support backlight, the displayed data is clear and easy to read, easy to operate even in low light. The new ball valve switch has more precise control and longer service life. The 1/4 inch standard interface design ensures the durability and universality of HVAC digital gauges.
• High Precision & Large Measuring Range & Switchable 4 Units The digital tachometer gauge adopts a high-speed microprocessor chip, which makes it more stable and reliable, and the accuracy reaches (0.05% measured value + 1). Measuring Range: Contact speed is 0.10-1999.9m/min, light source flicker frequency is 0.1-6000.0Hz, photoelectric speed is 9.0-99999RPM, contact speed is 1.0-19999RPM. The handheld tachometer supports switching between 4 units: RPM, Hz, m/min and ft/min.
• HD Display Supports Backlight Long press the unit key of the digital tachometer gauge to turn on or off the screen backlight. The backlight design of the screen allows the rpm tachometer to read data easily in low-light conditions. The LCD screen will display the measurement reminder symbol, battery power reminder, USB connection prompt, numerical display area, memory mark, unit display area, numerical lock, CONTACT symbol, maximum value, minimum value and PHOTO symbol.

Also included in the kit are alligator clips, LED stroboscopes, 1-to-1 connectors, 1-to-2 connectors, potentiometers, SRS connectors, standard probes, acicular probes, wire piercing probes and alligator clip to back probe needles. This multimeter test leads set is perfect for any hobbyist, auto mechanic, or electrical diagnostic technician.
• Wide Compatibility and Applications This multimeter test leads set is used to diagnose, test and repair complex vehicle circuits or electronic products, and can troubleshoot sensors, actuators, relays, fuses and electronic circuits. This test leads kit can be used with any multimeter and oscilloscope, suitable for 12v and 24v cars, RVs, trucks, marine and more, and can also be used in laboratories, homes and industries.
• Save Time and Money Multiple sizes of connectors are included in the banana plug test leads kit, so you don't have to stretch out the connector you are linking to causing additional issues later. You always have a lead to connect to the circuit, and you don't have to try to hold both leads in the proper position while trying to see what the multimeter is reading. This alligator test leads kit makes testing and troubleshooting automotive electrical systems and electronics much easier.
• Powerful Coolant Vacuum Refill Kit Perform vacuum pressure test and coolant vacuum filling service. Use an extra vacuum pump to work with this airlift coolant replenishment tool to create a vacuum in the cooling system, and then suck the coolant into the radiator. Quick replenishment system, no air pockets or hot spots are generated, to avoid distortion or other factors damaging the engine.
• Complete Coolant kit The cooler anti-leak kit includes a brass T-connector and universal taper plug, 4 adapters of different sizes (O.D. 35mm, 40mm, 45mm, 55mm), suitable for most types of vehicles. The adapter can be connected to the adapter on the air supply tool, and then the radiator cover sealing cooling system can be replaced to help radiator purification and coolant supply.
