PROMAX Test & Measurement, a privately owned company headquartered in Spain, was founded in 1963 with approximately 40 employees, and reported $13.1M in revenue as of 2023. The company specializes in telecommunications test instruments designed to provide testing solutions for cable, satellite, and digital terrestrial television.
PROMAX announced on March 10, 2026, it is slashing prices for its 4K Field Strength Meter and Fiber Optics products to 2006 rates, aiming to help telecommunications installers optimize operating costs without compromising equipment quality. Previously, on February 4, 2026, the company highlighted its Attenuation Test tool as essential for certifying the deployment and response of cabling and distribution equipment in television distribution plants, including Multi-Dwelling Units and cable networks. Earlier, on November 16, 2025, PROMAX emphasized the importance of the Optical Time Domain Reflectometer (OTDR) tool, noting that cable-based telecommunications increasingly relies on optical fiber, with key global carriers transitioning away from traditional telephone access lines. This followed an exploration on July 16, 2025, of the transition to SMPTE ST 2110, an IP network protocol gaining adoption in live production, playout, and contribution systems due to factors like enhanced scalability compared to SDI cabling.
