NESA is also the first Italian company to have developed First Class wind speed measuring devices that have passed the most stringent functional, performance and durability tests in compliance with regulations on wind monitoring.
NESA`s specialized engineers are highly experienced and work in partnership with major Italian and European Research Centres, designing and producing high-performance, innovative technological solutions tailored to specific customer requirements and always offering a high level of service.

Over 5500 stations installed throughout the world (as of 2017) in different climate conditions ranging from Siberian cold to Saharan heat, and one of the largest hurricane monitoring networks in the Caribbean (read the Storm Sandy article published in the WindEnergy trade magazine in 2013 and many other articles in the “Publications” section of our website), allow NESA to guarantee the performance and quality of its products and systems.

Production process

We offer a vast choice of products, ranging from individual devices to complete, turnkey measuring systems.
Our products are meticulously designed with special attention paid to actual usage conditions, in order to meet the most diverse requirements, whether it`s an individual device to be integrated into existing systems, a high-performance data logger, a wireless system, a remote measuring system or a data traffic monitoring system.

We provide our customers with the simplest, most appropriate solution to their specific requirements. Our manufacturing process, fully compliant with ISO9001 and ISO14001, involves detailed monitoring of each step, resulting in top-performance, high-quality products.
To guarantee the traceability of its products, NESA`s manufacturing process uses sample instruments certified by ACCREDIA or other major accredited test laboratories (Colonnetti, PTB, CNR, etc..) pursuant to Italian law No. 273/91. In the case of anemometers, a series of tests under increasingly stringent conditions are carried out with a view to obtaining Measnet certification specific for wind monitoring applications.
Certification of each primary tool and of the entire manufacturing chain enables us to offer our customers guaranteed, reliable products.

Production process

Research and Development

Nesa`s R&D team consists of highly skilled professionals who work in close partnership with Italian (ITC, Isac, etc.) and European Research Centres (Dewi, etc.) in designing and developing new, technologically advanced solutions.

After-sales service laboratory

NESA`s new headquarters at Via Crociera, Vidor, Italy also house a laboratory for device calibration and inspection. NESA offers its customers inspection, calibration and repair services for their sensors and data loggers. Each instrument that undergoes inspection and calibration is accompanied by a conformity report declaring its compliance with specifications, or an accurate quotation for repairing/replacing the device.
The laboratory features a double climatic chamber for calibration at varying temperatures and relative humidity, calibration systems for barometers, solar radiation sensors, rain gauges and multiparameter probes (chemical and physical parameters), as well as special, highly accurate calibration systems for data loggers and data acquisition systems.

Nesa is the first Italian company to have applied web technology to data acquisition systems (TMF500 in 2006 and TMF100 in 2008), patented the first rain/snow/hail gauge with low-consumption heating system (PL1000RLP rain gauge) resulting from thorough heat optimization and concentration studies, and applied reliable, versatile ZigBee standard protocol wireless systems to professional data acquisition devices (wireless sensors, 2009 and data loggers). As a result, Nesa products are currently used for controlling and monitoring the construction of some of the biggest structures for the Mose mobile gate system in Venice.

Commitment to Research and Development is a mainstay of Nesa`s activity aimed at improving existing products/processes and designing new solutions. In 2012 Nesa anemometers achieved First Class Certification. The inventiveness, skills and creativity of our R&D team are absolutely essential assets and strengths for our company.
