Measurements International (MI) was launched in 1987 as a company with expertise in the metrology instrumentation segment.

Over the years, MI has become a recognized global leader in this industry. Through active participation in organizations such as NIST and NSCL, Measurements International has developed a complete range of calibration equipment with very high accuracy for:

– DC Resistance
– DC Voltage
– Temperature
– AC Power
– Transformer testing

MI gained reputation as a supplier of leading technologies and solutions for metrology based on application knowledge through their dedication to quality and service. MI’s products are recognized as ‘Blue Box’ solutions.

Providing calibration services is another example of MI’s commitment and industry support. The accredited laboratory was certified level 1 ISOGUIDE 17025 as a result.

By recognizing the needs of the global utility industry, MI began developing new systems and technologies to accurately measure transformer losses in medium and large transformers years ago. The AccuLoss System™ provides transformer manufacturers all over the world the possibility to measure transformer losses with an accuracy unprecedented by other manufacturers.

Measurements International successfully supplied automated systems to each national laboratory, responsible for maintaining reference values ​​for temperature, resistance, voltage, current, and power at the highest possible accuracy. MI’s developers ceaselessly search for new advanced technologies for metrology applications.
In addition to these innovative products, MI has built a reputation for user-oriented on-site training, and highly qualified consulting and calibration services.

MI represents advanced products, excellent service, and comprehensive support for their customers when using these products. They are always happy to discuss customers’ metrological needs and to provide them with appropriate solutions for their metrology applications.

We don’t buy measuring instruments, we purchase solutions for specific measurement problems. I like to buy from TTMS, given their knowledge of test solutions in power electronics. I hate sellers. TTMS helps us to make the right choice. They even come up with instrumentation from manufacturers they do not represent themselves. And always with the perfect service: they are not complicated and just arrange what is needed.

In my role within the calibration and quality lab, it is a continuous striving for quality for me. In order to ensure this, the right support from, amongst others, suppliers is essential. TTMS understands this like no other, and I have been doing business with them for years. If I need to describe the business relationship with TTMS, it would be that it’s both constructive and instinctive. The measurement instrumentation is reliable. In addition to this, TTMS’ expertise of test and measuring equipment complements the STCA.
