The Alpha A 12 is a heating and cooling thermostat for cost-effective thermostating in the laboratory at temperatures from 25 up to 100 °C.  The thermostat is suitable for operation with non-flammable liquids (water, water/glycol) and for both internal and external thermostating tasks.  A 1-point-calibration of the thermostat can be carried out by the user.  The Alpha A can be used for any bath with a wall thickness of up to 30 mm by means of the screw clamp included in the scope of delivery.  Using the additional pump circulation set and a cooling coil, the immersion thermostat can be expanded to form a full-fledged thermostating system.  This well-priced equipment is made possible by minimizing any unnecessary features, with the focus on reliability and userfriendliness.
