High-performance and still full of power reserves or already used and posing serious risks to the system or machine. OELCHECK examines the quality of the lubricant and draws accurate conclusions thus avoiding expensive repairs, downtimes or unnecessary oil changes.

With the help of several physical and chemical values, OELCHECK can find out detailed information about the oil condition and the machine and support you to work out the optimal oil change intervals. Certain wear particles can be allocated to specific worn out machine parts and therefore function as an early indicator regarding possible damage.

Oil from construction machines, industrial facilities, cars, trucks, gearboxes or hydraulic systems – OELCHECK analyses all lubricants including many fuels and understands the message!
