PROSENSOR

What PROSENSOR does

PROSENSOR is a privately held French manufacturer and distributor of temperature sensors and environmental measurement equipment, founded in 1989 and headquartered in Norroy-Le-Veneur, France, with a secondary site in Amanvillers. The company employs approximately 13 people and operates multilingual websites serving French, English, and Romanian markets across Western and Eastern Europe. Its portfolio centers on Platinum RTD (PT100) temperature probes and thermocouple probes in numerous mechanical and certification configurations (including ATEX-rated variants), complemented by heating resistances, industrial controllers, signal converters, and sensor transmitters for CO2, humidity, and air quality.

A second pillar is data logging and weather monitoring, delivered largely through PROSENSOR's role as the French distributor for Onset's HOBO product line. This includes Bluetooth-enabled loggers (MX series), 4-channel analog recorders (UX120), waterproof loggers, soil and pH sensors, weather stations, and associated accessories, integrated via HOBOware (desktop), HOBOconnect (mobile), and HOBOlink (cloud). PROSENSOR complements this with proprietary SMART sensors that auto-configure with compatible loggers and offers HOBOware Pro, a 21 CFR Part 11–compliant variant for regulated pharmaceutical use.

The business model is hardware sales via direct e-commerce (prosensor.com / .fr / .ro), phone, and email, with quote-based pricing on multi-year contracts and no public price list. End markets span industrial manufacturing, research and laboratories (primary), pharmaceutical cold chain, energy audit services, and agriculture/environment. The company is ISO 9001:2015 certified through 2027, holds no external funding, and reports no acquisitions or leadership changes. Vertical-specific sub-brands greensensor.fr (composting) and pharmasensor.fr (pharmacy) signal targeted expansion within the broader environmental-monitoring thesis.
