For rapid diagnosis of suction pressure. Within seconds, the function of the compressor and the fill level of the vehicle’s air conditioning system can be checked.
Ideal aid in the dialogue reception process.
Application with R134a pin valves.
Practical tip: If the temperature does not reach below 10°C, the pressures in the air conditioning system should be measured. A normally functioning system reaches 0.5–3 bar on the low-pressure side and 6–20 bar on the high-pressure side during operation. With variable-speed compressors, the pressure on the low-pressure side is a constant approximately 2 bar.
