What aoip does

AOIP is a French designer, developer, and manufacturer of precision test and measurement instrumentation and motor control systems, founded in 1896 and headquartered in Ris-Orangis, France. The company operates two sites in metropolitan France: the Ris-Orangis headquarters housing design, manufacturing, and the SOFIMAE COFRAC-accredited calibration laboratory, and a technical maintenance and repair center in Fretin. AOIP's product portfolio is organized around five technology pillars: multifunction calibration instruments (CALYS portable and benchtop series), primary and industrial temperature metrology (including Isotech Model 526 ultra-low temperature calibrators and the MicroK² precision thermometry bridge), pressure calibration (ADT 710 automated gauge reader with AI vision and Additel pressure controllers), data acquisition and recording systems (FD, DATALOG series), and motor starting systems (EPM, RLV, RED, and NS3 starters for slip-ring and cage motors up to 20 MW). The company also distributes complementary instruments from partners Isotech, Additel, and Pontarlier Electronique.

The business model is hybrid: AOIP generates revenue from hardware sales, COFRAC-accredited calibration services delivered through its wholly-owned SOFIMAE subsidiary, equipment rentals (minimum 7-day duration in France/EU, 14 days internationally), installation/commissioning/training, and maintenance contracts via the Fretin service center. A custom instrumentation engineering service targets bespoke sensor and measurement system design for automotive, aerospace, pharmaceutical, and energy applications. Go-to-market is enterprise field sales: a regionally distributed direct sales force covers all metropolitan France, a dedicated export team handles international markets, and a network of authorized distributors extends reach globally. Pricing is project-quoted with standard payment terms of 30 days end of month and minimum order values of 230 EUR HT (France) and 500 EUR HT (international); 30% deposits apply to custom orders above 7,500 EUR HT.

AOIP's regulatory positioning rests on ISO 9001 certification (AFAQ) and three COFRAC accreditations held by SOFIMAE — Temperature (N°2.1525), Electricity-Magnetism (N°2.1144), and Time-Frequency (N°2.1227) — making it one of a small set of French firms offering accredited calibration across all three domains. The customer base spans industrial metrology laboratories, telecommunications/RF operators, heavy industry and mining end-users of motor starters, and pyrotechnics/defense (expanded through the February 2023 acquisition of Nimtech). AOIP operates as a privately held independent company within the Asgard Group structure, with no disclosed external funding rounds and no public listing.
