- 【Compatible with R134a / R1234yf system】 This auto air conditioning system oil tester is designed for R134a / R1234yf system oil. For accurate results, it is important to ensure sufficient refrigerant in the vehicle before conducting the test, ensuring no shortage of refrigerant during the detection process.
- 【Why need it】 Many air-conditioning compressor failures are caused by low oil levels and dirty oil in the air-conditioning system. Using this low-cost oil checker can save you the cost of a new compressor and the downtime caused by replacing the compressor.
- 【Main Function】This AC oil checker is used to detect the oil level of air conditioner and harmful acids in the oil of air conditioner system without changing the air conditioner system and draining all the oil in the system.
- 【Simple and Efficient Operation】 Align the refrigeration oil testing instrument with the low-pressure port, press it firmly, and release immediately without any prolonged pause. Repeat this process twice, providing a rapid and efficient way to measure the oil level status of your car's air conditioning system.
- 【Convenient Testing Conditions】 To perform the test for this A/C oil tester, open the car doors or lower all four windows, set the airflow to maximum, and adjust the temperature to a lower setting. Let the vehicle run for a few minutes, and you're ready to conduct the oil level check, ensuring optimal testing conditions.
