Expert UK Calibration Services and Electrical Testing Equipment from GNW Instrumentation

GNW Instrumentation is an expert in providing quality calibration services and electrical testing equipment to a range of different industries across the UK. For over 40 years, we have built an excellent reputation for quality production and repair of pressure gauges, data loggers, temperature sensors, and more. 

With our years of experience and embrace of state-of-the-art technology, we combine old and new calibration technology to provide a service that reduces downtime and delivers the best results for your site. 

At GNW we offer a range of quality services that ensure accurate results and practical storage solutions. Our on and off-site calibration and certification is designed to help you achieve complete accuracy from your electrical testing instruments, and our other support such as repairs and manufacture of custom instrumentation are equally as important to us and our customers. 

Our services are particularly useful in the medical industry, for electronic equipment such as blood pressure monitors. These must be calibrated regularly to produce efficient results, and we find that many of our customers in the medical industry rely on our engineers' professional calibrating experience to ensure that there is very little room for error. 

Much of our equipment is designed and built by hand at our factory in Southport, UK. We can also offer consultation services across the UK, and can deliver on-site surveys to keep your operation flowing with minimal disruption. 
​
Our online database can also help you keep track of your instrumentation and when it is necessary to re-calibrate your electrical and  mechanical devices. Visit the Instrument Track Calibration Database page for more information about this service, or call us on 01704 536 010 to see how we can help your business.
