What Richard Paul Russell does

Richard Paul Russell Ltd designs and manufactures precision electronic wind and weather monitoring instruments, data loggers, and IoT sensor systems from its base in Milford on Sea, England. Founded in 1992 by Richard Russell, the company has built a specialised portfolio that includes the SpaceLogger data logger family (10, 50, and 100 series with SD-card, WiFi, and Ethernet connectivity), the rpr-IoT LoRaWAN sensor node range, and the WeatherFile.com cloud platform that provides 24/7 live data access for deployed weather stations. The company also distributes third-party products including Kestrel handheld weather meters (developed since 1994 with Nielsen-Kellerman) and Gill Instruments sensors (MaxiMet, WindSonic, WindUltra, MetConnect), and offers specialised solutions such as Plumecast atmospheric dispersion modelling for COMAH and nuclear sites, the OWS-5 moving-platform wind system co-developed with the British Olympic team, and tower crane weather monitoring systems in partnership with ATLAS.

The company operates a hybrid go-to-market combining direct e-commerce sales via its r-p-r.co.uk storefront with a network of exclusive international distributors covering France, Netherlands, Norway, South Africa, and the USA. Revenue is generated primarily through one-time hardware sales (Kestrel meters from £78 to £988, Gill MaxiMet sensors from £983 to £2,700, SpaceLogger units from £175 to £368), bespoke custom/OEM data logger design services for enterprise clients such as Eschmann, MDS Medical, Prestige Medical, Mettler Toledo, Bombardier, and the Maritime Authorities, and an emerging annual subscription stream via Plumecast (priced at £3,000 per year). Customers span multiple verticals including agriculture, marine and sailing, construction and tower cranes, laboratory and healthcare, industrial safety, ballistics, and scientific research, with a headquarters team of 1-10 employees and no external funding.
