Flo-tech has been a leading brand of portable testers and turbine meters for hydraulic fluids for over 45 years. Over the years, the Flo-tech tester line has undergone a progression of design changes that have enhanced its operational features while maintaining the rugged dependability of that first tester. Continuing with that tradition is the Flo-Check® USB Hydraulic System Analyzer and the MC4000, the next generation of hydraulic test equipment. The tester line includes three additional models: PFM6, PFM8 and Sensor Array. In addition to the hydraulic testers, Flo-tech also offers a full line of turbine flow sensors in four models including: Activa, Ultima, Classic, and Quad.
