20 years of TT210
The 6th of May 2008, marks the 20th anniversary of the TT210 Temperature Recorder. The TT210 is a special instrument: A chart recorder with a Pt100 sensor that is portable and will run 4-6 weeks on a standard 9V alkaline battery. Back then the TT202, which has a bimetal sensing element, was very popular, but we got quite a few enquiries for a similar instrument with a remote sensor. The TT210 was developed with the help of many people, importantly Ole Andersen from our old company HBO Instruments, Copenhagen, and Bob Fairweather from Philips at Hendon. It was originally made with a hybrid circuit, the forerunner for the integrated circuits. Among the users are hospitals and laboratories, where the high accuracy and portability makes it very handy.
