AvCount3 Particle Counter for Skydrol
The AvCount3 for Skydrol is a compact bench-top automatic particle counter, specifically designed to measure the particulate of Skydrol hydraulic fluid.
Skydrol is an advanced fire resistant aviation hydraulic fluid which inhibits corrosion and prevents erosion damage to servo valves. It has been approved by most airframe manufacturers including Airbus, Boeing and BAE Systems and has been used in their products for over 40 years.
Due to the highly corrosive nature of Skydrol material this special version of the AvCount3 is fitted with Isolast seals and a protective inner case.
