Cleanliness tester

The Cleanliness Tester is an advanced instrument for detecting and analyzing particle contamination on automotive parts, new energy power battery components, and other precision-engineered products. The system automatically counts and classifies impurity particles on filter membranes by type, size, and quantity, providing standardized reports aligned with automotive and medical industry standards.

Application

(1) Automotive Powertrain Components: Engine parts, fuel injectors, transmission components, and precision metal parts.

(2) New Energy Battery Parts: Lithium-ion battery electrodes, separators, and casings for electric vehicles.

(3) Medical Devices: Sterile surgical instruments, medical implants, and single-use disposable devices.

(4) Aerospace Components: Turbine parts, hydraulic systems, and avionics housings.

(5) Defense & Military CB Equipment: Protective gear and sensitive equipment requiring ultra-clean surfaces.

(6) Industrial Manufacturing: Precision machined parts, semiconductor components, and hydraulic systems requiring particle-free assembly.
