What GP:50 NY does

GP:50 NY LTD, founded in 1986 by Donald J. Less in Grand Island, New York, is a privately held designer and manufacturer of instrumentation-grade pressure, level, and temperature sensing equipment. The company operates from a single manufacturing facility near Buffalo, NY, and sells to customers across the United States, Canada, and international markets through regional sales representatives and an e-commerce storefront at shop.gp50.com.

The product portfolio spans 117+ SKUs organized across cryogenic/high temperature, differential, digital, flush diaphragm, gauge/vacuum/absolute pressure, high accuracy, sanitary, submersible/subsea, and temperature categories, alongside a complementary accessory line of junction boxes, surge protectors, digital indicators, cable hangers, and signal conditioners. Core technology is built on strain gauge-based sensors with proprietary digital correction circuits, flight-heritage sensor designs for aerospace and defense applications, and remote-mounted electronics for cryogenic and extreme-temperature environments. Products are qualified for operation from -320°F (-196°C) cryogenic to +500°F (+260°C) extreme heat, subsea depths to 30,000 feet water column, and pressure ranges from 0-5 inches WC to 100,000 PSI, with high-accuracy models achieving ±0.05% FSO static accuracy.

Revenue is generated through direct hardware sales to aerospace, automotive testing, industrial automation, oil and gas, general testing, water treatment, and sanitary/food and beverage customers. The commercial model combines quote-based custom and enterprise sales with multi-year contract structures for specialty and large-volume orders, alongside direct online purchasing for select standard products and accessories. The company holds AS9100D with ISO 9001:2015 and a broad portfolio of industry certifications (NIST, CSA, HART, FM, ATEX, CE, 3A, EAC, IEC, CRN, UL 479B), and operates two related entities: a wholly-owned Melt Pressure Division (gp50meltpressure.com) and an affiliated Blue Ribbon Corp focused on pressure gauges for water treatment.
