The PPC Portable Particle Counter is an intelligent, lightweight, and effective precision laser oil contamination analysis tool created specifically for sampling and testing. It can simultaneously monitor numerous factors, including oil pollution, moisture, and temperature. It has various capabilities and can indicate the status of the hydraulic and lubrication systems in real time, allowing equipment maintainers to intervene early to prevent pollutants from wearing or harming hydraulic system components. This not only lowers repair costs, but also minimizes overall equipment downtime, enhances system safety, and extends equipment service life.
