The AvCount2 Skydrol instrument is 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 AvCount is fitted with Isolast seals and a protective inner case.

Additional Information

The AvCount uses the light obscuration principle, where the fluid under test is passed through a cell comprising a laser and a calibrated sensor. Particles in the fluid cast a shadow onto the sensor, which determines the area/diameter and number of particles in the sample.

The AvCount2 Skydrol is controlled via icons or a virtual keyboard using the colour touch sensitive screen. Results are displayed in real time and are simultaneously printed out on the compact integral printer. The test methods embedded in AvCount2 Skydrol cover a range of fuels, lubricating oils and hydraulic fluids. Test methods can be edited to create custom test profles. Avcount2 Skydrol utilises 16 point calibration and can be re-calibrated on-site by a Seta trained engineer.

Improved connectivity and better memory management allows results to be accessed, printed out or downloaded to a memory stick via the USB port, or to a personal computer via the RS232 Port. The avcount2 can also be controlled via the RS232 port.
