Ultratemp UT 3505 W

LAUDA Ultratemp process thermostats enable exact regulation to an external temperature within a range of −5 to 60 °C. Their high temperature stability of ±0.5 K guarantees a precise temperature in the application. The water-cooled design minimizes the heat emitted to the environment. Use with the non-flammable liquids water or water-glycol provides easy handling and low operating costs.
