About Us

Gemini Data Loggers UK: manufacturers of Tinytag data loggers.

Our vision is to become the best provider of robust environmental data solutions through our reliability, innovation and responsiveness.

Located in Chichester, West Sussex, Gemini Data Loggers has been manufacturing data loggers since its establishment in 1984, and introduced the first branded Tinytalk temperature logger to its own design in 1992. In the same year Gemini Data Loggers began international trade through distributors such as RS Components and Intab Interface.

The company quickly expanded its range with a relative humidity logger in 1993, before going on to produce the first Tinytag and Tinyview loggers in 1994 and 1996. Around this time there was significant expansion with Gemini Data Loggers successfully exporting to Japan (1994), the Pacific Rim countries, including Australia (1995), India (1996) and South Africa (1996).

Gemini Data Loggers now trades globally with a network of over 40 distributors. Tinytags have an established reputation for quality, reliability and value for money, and are used throughout the world in a range of industries and applications. All Tinytag products come with a 12 month warranty from the date of purchase.

As well as manufacturing data loggers, all Tinytag hardware, firmware and software is designed in-house, enabling tight quality control and the flexibility to respond to customer needs. Proud of its innovative designs, Gemini Data Loggers is committed to on-going product development with 10% of its revenue spent on development. While the extensive range of off-the-shelf data loggers and probes suit most requirements, Gemini's engineering team are able to develop custom solutions adapted to the requirements of particular applications.

Gemini Data Loggers operates a Business Management System (BMS) which includes our Quality and Environmental Policy and conforms to ISO 9001 and 14001.
