CatLABS Universal Tank Top Timer (compensating development timer)

Description

CatLABS Universal Digital Darkroom Timer (for any enlarger and safelight)
The CatLABS “Tank Top Timer” is a convenient small-sized temperature-compensating timer designed to be fitted to any developing tank cap.
It functions as a stopwatch, starting when the button is pressed and counting
up until the button is pressed again.
The rate at which the timer runs is dependent on the measured temperature, and in this way provides accurate compensation for changes in developer temperature.
The timer can also be used as an accurate digital tank thermometer, measuring to a resolution of 0.1 °C.
