Yokogawa Measurement Technologies Ltd


Since founding the Electric-Meter Research Institute in 1915 Yokogawa has grown into a multi-billion Dollar global company with annual revenues of over $3.5bn and employing over 20000 people world-wide. The Test & Measurement organisation represents the company’s second largest division with a turnover in the region of $1bn and supplies high quality, high reliability measurement solutions (primarily for electro-mechanical type applications - but not exclusively) into a diverse range of markets which include:

Aerospace & Defence
Consumer Electronics
Power Generation

The division has a very broad portfolio of Test & Measurement instrumentation which includes:


Oscilloscopes, also called Digital Storage Oscilloscopes (DSOs) or Mixed Signal Oscilloscopes (MSOs), are a common type of test instrument used to capture, analyze, and troubleshoot electrical or real world physical signals. Oscilloscopes observe the change of electrical signals over time, continuously graphed on a display as voltage or amplitude vs. time. During observation, oscilloscopes can analyze waveforms parametrically (i.e. frequency, RMS, peak-to-peak amplitude, rise time, etc.) Non-electrical signals, especially mechatronic signals such as vibration, strain, temperature, or current can be converted to voltages and displayed.

Power analyzers

Power analyzers accurately measure electrical power characteristics of devices that generate, transform, or consume electricity. Power analyzers, also called power meters or wattmeters, provide precise measurements of true power (watts), power factor, harmonics and efficiency in inverters, motor drives, lighting, home appliances, office equipment, power supplies, and industrial machinery.

With advances in energy efficiency and standby power, there is an increasing demand for accurate and reliable power measurements. Highly stable and reliable power analyzers enable engineers to minimize energy loss due to distorted, transient waveforms in power electronics such as inverters, motors, lighting circuits, and power supplies. Yokogawa, the world's leading manufacturer of electrical power analyzers, provides a broad selection to satisfy all requirements

Optical test equipment

Optical test equipment or optical measuring instruments are used to measure and characterize the physical properties of light. The insatiable demand for higher capacity in communication networks has fueled the need for highly precise optical test solutions. In addition, precision optical measurements are essential to optical research applications for biophotonics, environmental sensing, and consumer products.

R&D engineers, academic researchers, manufacturing engineers, and field service personnel depend on precision optical test equipment to ensure design and performance specifications, production quality, and network health. For more than thirty years, Yokogawa (formerly Ando) has delivered quality, consistency, ease of use, and market leadership for optical test applications

Portable and handheld instruments

Yokogawa’s Portable and Handheld Instruments offer a broad range of portable test equipment to fulfill numerous short-term or continuous measurement application requirements. Included in our wide range of products are: Calibrators, DMM, Clamp-on Testers, Portable Power Monitors, Portable Data Loggers, Insulation Testers, Thermometers, Portable Analog meters, Light Meters, Precision Measuring equipment, and more

Data acquisition (daq)

Data acquisition (DAQ) is the measurement, recording, analyzing, and presentation of real world phenomena. It includes electrical measurements such as voltage, current, power as well as measurements through sensors and transducers including temperature, pressure, strain, vibration, and more. Selecting the ideal data acquisition components or solution depends on your application. Typical factors include sample rates, channel scalability, signal conditioning, sensor types, analysis capability, mobility, and environmental conditions.

Yokogawa data acquisition solutions are recognized for industry leading measurement accuracy, noise tolerance, signal conditioning, triggers, simultaneous sampling, streaming, and build quality. ScopeCorders have the advantages of an oscilloscope and a DAQ system, packaged in a clever bench top interface
