Our Story

Business Presentation

1972 Laboratori di Strumentazione Industriale (LSI) Spa is organized in Milano by former members of a previously existing electronic research company (LRE) and begins the production of electrical thermometers. Soon afterwards, the company adds systems to measure relative humidity through the psychrometric method and hot-wire anemometers to his portfolio.

1975 The company introduces graphic recorders for the online printing of the measured values and a line of converters for the connection of sensors to industrial systems. In just a short time, the range of products and measured quantities is remarkably increased with the introduction of sensors for the measurement of different types of temperature: radiant, contact and of liquids, along with luxmetric sensors and hygrometers.

1979 Introducing the LASTEM logo, the company begins the production and distribution of his line of sensors and data acquisition systems specific for meteorological applications. LASTEM Srl is now operative.

1980 LSI is the first company in Italy to produce instruments for the measurement and storage of the thermal environments parameters requested in the health and safety regulations in working environments.

1985 LSI and LASTEM transfer their head offices from Viale Liguria (Milan) to the current Settala (MI) headquarters, consisting in three twin buildings.

1990 After the consolidation of computer technology and storage possibilities, LSI develops a series of PC-compatible acquisition systems and software.

1995 New concept of measurement is then started: multi-measurement system – one single system able to measure not just a few parameters, but a whole range of quantities which, altogether, can solve a specific application need. The multi-measurement concept has been a company mainstay since, widening the range of sensors for the measurement of environmental quantities such as gas concentration, thermic flows, lux and radiation.

2000 LSI further develops its range, with a new sensor line equipped with data transmission via radio to data acquisition systems.

2004 LSI creates the new “After-Sale Services” division, designed to offer support and service after the purchase of the instruments: Telephonic Assistance, Data Collection, Repair Service and External Assistance.

2006 LSI and LASTEM are united under the same brand and logo, with the new LSI LASTEM name.

2010 A new concept of multi-position measurement is started: thanks to radio technology applied to data loggers and sensors, the multi-measurement concept is extended to a multi-position concept. Now LSI LASTEM can develop complex systems producing simultaneous measurement of a number of parameters in different positions of the targeted environment.

2013 LSI LASTEM participates in the Proactive project (Protection of the territory with advanced ICT infrastructures, active citizenship, and social networks) which sees the collaboration of two research institutes (Politecnico di Milano and Cefriel), three important companies (Vodafone Italy, Metrapolitane Milanesi, Tea) and five SMEs (LSI Lastem, WebRatio, Me-Source, Pipetech, Gulliver). As part of this project, LSI LASTEM began the design of LeakWatch, an automatic system for monitoring water infiltration into the ground caused by damage to the embankments.

2015 The first prototype of G.Re.T.A. is born, evolution of LeakWatch. LSI LASTEM opens up a new market sector: Geophysics.

2019 LSI LASTEM begins the migration of its software for data processing to the CLOUD solution, a confirmed choice both for specialist applications and for the data acquisition and storage modules.

Mission LSI Lastem

Our Mission

LSI LASTEM’s mission is to be a reliable and flexible Partner, providing a technological product able to fully satisfy the performance and functional requirements requested by customers, supporting them on a technical level in choosing the best technical solutions.

In order to successfully pursue the corporate mission, LSI LASTEM is inspired by the following principles:

  • constant attention to product requirements and customer requests
  • incessant commitment against inefficiencies, defects and waste
  • involvement and enhancement of employees
  • technological renewal to diversify the products offered
  • analysis of the main needs of the interested parties (for example: Customers, Property, Employees, Suppliers, Public Administration)
  • commitment to comply with environmental compliance obligations
  • continuous improvement of the environmental and quality management system
  • pollution prevention.

Specific objectives are defined annually in order to monitor the pursuit of the above principles.


LSI LASTEM firmly believes in the continuous improvement of its internal processes as a strategy aimed at achieving the highest quality standards of products and services, for the complete satisfaction of its customers. For this reason, since 1999 it has been certified according to the ISO 9001:2015 standards for the design, production and after sale service of equipment for environmental measures.

Moreover, environmental protection is a fundamental value for LSI LASTEM which, for several years, has been pursuing sustainability policies aimed at reducing its carbon footprint. The installation of a photovoltaic system and charging points for electric cars are some recent tangible examples. Accordingly, LSI LASTEM has certified its environmental and energy management systems according to ISO 14001:2015 .

Finally, LSI LASTEM’s commitment to protecting the health and safety of its employees is acknowledged by the ISO 45001:2018 certification, the international standard that disciplines the requirements to ensure safe and healthy workplaces.

The 20th century had been “the production century” and the 21st century would be the “quality” century.

Head Office

LSI LASTEM headquarter in Settala, near Milano, Italy is a 1325 m2, 3 twin-building structure that’s been home to our company since 1985. Here, a team of 30 professionals is employed in engineering, production, aftersales, marketing and administration departments.

Each and every LSI LASTEM product is designed, developed and tested here. Our skill set includes physics, mechanics, electronics, firmware and software engineering.

Mechanical Shop
The backbone of LSI LASTEM products takes shape in our in-house shop. Our expert craftsmen produce here sensor bodies, supports and mechanical components.

Sensors assembly division
Given our extensive range of sensors, this is always one of the busiest areas of the company. After completion, sensors are moved in the nearby calibration laboratories for testing.

Data Loggers Assembly division
Data Loggers are the absolute core of our systems. Here they are assembled, configured and tested – the latter activity lasts for a 7-day period.

Calibration Laboratories
To ensure consistent and dependable performance, we calibrate each sensor against traceable standards in a specific calibration facility.
Our laboratory is accredited by ACCREDIA Italian Accreditation System, the National Body for accreditation activities, equivalent to ISO/IEC 17025.

We have a skilled, dedicated team for aftersales services. Their duties include repairs, calibrations, on-site installations and maintenance.
In addition, we perform data management services to our customer – data download, validation and web publication.

We have always believed in the benefit of offering training for our customers to make the use of our system more productive and easier. That’s why we have a dedicated room for our year-round training seminar program.
