Multifunction Automatic Recording Photometric Titrator

The First 110 Years of Laboratory Automation: Technologies, Applications, and the Creative Scientist

“…A solenoid-operated burette valve could be triggered by the photometric end point, whereas others used recording devices capable of generating first, second, and even third derivative plots so that the operator had a choice of end point determination. 52 The first mention of a computer for use in conjunction with automation was in 1948. The Reeves Instrument Corporation introduced "an office-size electronic computer.…”

Ultraviolet Spectrometry

“…Streuli's review (139) also contains items of interest. In instrumentation, a recording photometric titration was described (99). Ionization constants of a number of triazine derivatives have been published (61).…”
