Hyradulics & Pneumatics - Clark Testing

Hydraulics & Pneumatics Testing



Clark Testing has been active in testing hydraulic-pneumatic components and systems for over 20 years. Products tested range from automotive fuel filters to 15 inch diameter hydraulic actuators. A large selection of equipment, instrumentation and test benches are available to support your testing program. Component performance can be evaluated over a temperature range of -346° F to +600° F.

Clark Testing is proud to continually maintain its certification to ISO/IEC 17025:2005 accreditation, certificate number L2163.

Clark Testing hydraulics and pneumatics testing is primarily suited for applications in aerospace, automotive, heavy equipment, military, nuclear, power generation, and rail and transportation. However, we are constantly expanding our services, so contact us with your needs for customized hydraulic and pneumatic test programs.
