Model 801A from PolyScience has analog control.

Model 801A has analog control and is suitable for applications where frequent changing of temperature settings is not required. With a manual temperature dial set, the unit requires reading the resulting temperature on a thermometer. FromPolyScience, the heating circulator occupies less than 9 x 15" of space on the benchtop, and the 1,000 W heater provides fast response and stable heating. The unit has a 6 l reservoir, temperature range from 41 to 212°F (5 to 100°C), stability to I32°F (I0.2°C), and a two-speed pressure pump.
