CAYLAR

What CAYLAR does

CAYLAR is a French manufacturer of precision scientific instrumentation for magnetic field generation, measurement, and regulation, founded on April 10, 2002 by Jean-Claude Germain and headquartered in Villebon-sur-Yvette (Essonne, Paris suburbs). Operating as a private SAS with approximately 10-15 employees and share capital of €37,000, the company is the only entity worldwide to claim mastery of all three components of a complete magnetic system: current sources (power supplies), electromagnets, and NMR and Hall technology gaussmeters. The firm draws on over 60 years of combined expertise by absorbing legacy know-how from DRUSCH (NMR gaussmeters since the 1960s) and BOUHNIK (power supplies), and continues to service instruments dating from that era under a 20-year component stock guarantee.

The core product portfolio includes NMR Teslameters (NMR20, NMR25-4) using Nuclear Magnetic Resonance for absolute magnetic field measurement at <10 ppb accuracy in uniform fields and 100 SPS acquisition speed, Hall Teslameters (DTM-133, DTM-151, HPC, HPCS) distributed from Group3 Technology, a range of Electromagnets from the 27 kg EA50H (2.37 T) up to the 1,450 kg EA300H (4.79 T), and MPU-series power supplies with stability classes from 50 ppm down to 0.1 ppm with NMR regulation. Custom solutions extend to ultra-high vacuum chambers, magnetic system integration (e.g., NMR-EA300 calibration bench), and the MFG Magnetic Field Module for Park Systems AFM platforms. CAYLAR also offers ISO 17025-compatible calibration services and maintains instruments with full traceability.

CAYLAR runs a direct enterprise sales model serving scientific research institutions, MRI manufacturers, particle accelerator facilities, metrology laboratories, and (increasingly) industrial researchers across Europe/Africa/Turkey, Japan, North America, China, the South Pacific, and South America. All products are priced in EUR via quote-based sales, with payment terms of a 20-30% deposit and balance due within 30 days of invoice. Indicative prices range from €3,100 for NMR probes to €64,450 for the EA300H electromagnet, with custom electromagnet design available up to 3,000 kg. Beyond its magnetic systems core, CAYLAR has diversified into intelligent textiles and haptic communication technology through the DGA CENTURION program with Safran and the AID-funded MATEP project with MEDES and Toulouse University Hospital, targeting defense, rehabilitation, and sports applications.
