The NSXi family of smart meters has been developed with highly durable materials, advanced technology and is produced with all the care of Electrostatic Discharge. The NSXi line is stable, robust and durable. Our meters have a useful life of 15 years.
Historically critical electronic components, such as the LCD display, have been developed foreseeing the high temperature (85 ° C) and humidity (87% RH) variations found in several Latin American countries, always in agreement with the good practices and the latest ABNT standard dealing with this subject, NBR16078.
Another striking innovation for the high reliability of Nansen smart meters is that electrolytic capacitors, a common component in energy meters, have been virtually eliminated in the NSXi development project. Ensuring unprecedented levels of reliability in electronic meters.
We constantly invest in quality testing and simulation of wear and aging of meters. Always with the purpose of guaranteeing our excellence in quality and reliability. The Nansen Quality Laboratory is in compliance with all current INMETRO standards and qualified to perform inspections and tests even for other manufacturers in our segment.
