Our Company

Providing the industry with the most advanced predictive maintenance testing and troubleshooting tools since 1985

ALL-TEST Pro (also referred to as ATP) is a U.S.A. incorporated company that develops and manufactures predictive maintenance (PdM) equipment for testing all types of AC & DC electric motors.  ALL-TEST Pro has won numerous awards for its products and patented technologies.

The company is most known for its development of the patented Motor Circuit Analysis (MCA) technology. Motor Circuit Analysis (MCA) is a fast, accurate, non-destructive test that determines the health of specific components within electric motors. The 3-minute test uses proprietary algorithms to quickly determine the status of the stator, windings, rotor and cabling, by assessing and grading the components of the motor to determine the overall health of the electrical motor. All ATP instruments are hand-held and portable for field testing. ALL-TEST Pro motor testing instruments are currently the only devices in the world that can accurately detect early faults in motors.

ATP also sells online (energized) testing instruments which utilize Electrical Signature Analysis (ESA) technology. ESA is capable of testing incoming power and associated power issues (similar to a megohmmeter) but also analyzes the entire load of the process while operating. Used in the Predictive Maintenance (PdM) industry, ESA allows maintenance managers to adjust, correct, and plan repairs to avoid potential downtime, motor failures and ineffective operations leading to additional wasted resources, such as raw materials, energy, man hours, and equipment.  

Since 1985, ALL-TEST Pro has provided the industry with the most advanced predictive maintenance (PdM) testing and troubleshooting tools for AC and DC motors, coils, windings, transformers, generators and more to a wide range of industries worldwide.

Research and Education

ALL-TEST Pro also takes an active role in electric motor system energy and reliability research. Key projects have included the first ever US Department of Energy Best Practices technology transfer project, including the coordination and co-funding of a reliability upgrade to the latest version of the US DOE’s MotorMaster Plus software (Dreisilker Electric Motors and Pruftechnic were co-partners) and designing the Electric Motor Performance Analysis Tool for Pacific Gas and Electric (PG&E). ALL-TEST also contributes and consults to EPRI, US DOE, university, utility and related electric motor energy and condition research projects as well as scheduled motor management and MotorMaster Plus training.

Motor Diagnostics Training

To complement our line of motor testing instruments, ALL-TEST Pro offers Motor Diagnostics Training Seminars where participants can learn to diagnose ALL electric motor systems and establish a predictive maintenance program. MCA seminars will teach you how to easily troubleshoot and carry out predictive maintenance analysis. ESA seminars will prepare you to evaluate many types of electric motor systems to improve the reliability and uptime of your plant. These seminars will improve your plant’s operation, reduce downtime, minimize failures and increase profits – all while earning valuable CEUs.

About ALL-TEST Pro

ALL-TEST Pro is a leading manufacturer of electric motor predictive maintenance (PdM) equipment and condition monitoring tools. ALL-TEST Pro electric motor testing devices surpass other instruments by accurately and quickly diagnosing motor health issues to ensure electric motor reliability and reduce unnecessary facility operational and repair costs. All diagnostic instruments are handheld and lightweight making them exceptionally suitable for field testing applications. The current line of motor testing devices use Motor Circuit Analysis (MCA), a proprietary technology developed by ALL-TEST Pro, and electrical signature analysis, to evaluate electrical issues of components within motors. ALL-TEST Pro products are widely used in nearly every industry that uses electric motors, generators or transformers, and are available worldwide.
