Our Company

Weatherall Equipment & Instruments Ltd. was originally founded in the 1950’s by Mr Helmut Weatherall, who used to supply, together with mining equipment, Riken Keiki gas detectors to the British Coal Board for use in all UK coal mines. Riken’s pionieering Interferometer, the Model 18 for Methane, was used extensively for many years.

Today, Weatherall remains a private UK company, working from modern premises in Wendover, Buckinghamshire. We continue to be the exclusive UK & Ireland distributor and Authorised Service Centre for gas detection products (including marine fixed systems) manufactured by the Riken family of companies: Riken Keiki Co., Ltd.
