What Rieker Inc: Rieker Instrument Company does

Rieker Inc. (Rieker Instrument Company) is a Pennsylvania-headquartered, privately held manufacturer of precision angle and motion sensors, including mechanical inclinometers, electronic inclinometers, accelerometers, tilt switches, and aircraft fuel system attitude indicators. Its product portfolio spans low-cost mechanical units (e.g., 1000-5000 series priced from approximately $34) through mid-range electronic sensors (H6, H6EX, H4360, RDI/RDS series priced $535-$1,431) to higher-value integrated systems such as the MPI touch-screen precision inclinometer and the BH3 rugged CAN J1939 sensor. Underlying technologies include precision glass-tube-and-ball mechanical inclinometers with proprietary damping fluid, MEMS-based electronic sensors with integrated temperature compensation across -40 to +85C, and liquid capacitive sensing (H4 series). The company also offers packaged Total Solutions — the ADAM ADA sidewalk and curb-ramp assessment system and the CARS Curve Advisory Reporting Service — that combine Rieker sensors with software, photogrammetry, and computer vision. Distribution includes direct e-commerce, phone, and email sales as well as distribution of Seika-brand sensors (NG, NGi, NGu, SB, BDK, B series) and OEM/quantity pricing.

The company sells primarily to enterprise and government buyers across aerospace/defense, aviation, construction equipment OEMs, federal and state departments of transportation, mining, marine, and professional audio end markets. It holds ISO 9001:2015, CSA, CE, and RoHS certifications, and specific aviation models (e.g., 1017S5) are FAA 8130-3 certified under PMA, while the RDS7-BB Digital Ball Bank Indicator has been the U.S. DOT's adopted standard electronic measuring device for curve speed advisory since the 1990s. Owner/CEO Vida Javan leads the company, which is reported with 51-100 employees, no parent company, no disclosed outside investors, and active job postings suggesting ongoing engineering investment.

Go-to-market is direct-to-customer across all primary channels: an e-commerce storefront at riekerinc.com with application-, industry-, and specification-based filtering; phone sales at 610-500-2000 for custom and FAA-certified configurations; email inquiry and OEM/quantity pricing for enterprise buyers. Revenue is overwhelmingly hardware-driven, with custom/semi-custom configuration as a recurring high-margin substream and ADAM/CARS representing an early attempt to layer software/analytics on top of the core sensor franchise.
