The Grant Optima™ GD100K is a general purpose microprocessor controlled digital immersion thermostat with an exceptionally simple user interface. It provides digital control for simple, effective temperature control in the range of 0 to 100ºC.
The GD100K can be used in combination with the
Grant S and P ranges of stainless steel and plastic tanks or with other vertical sided vessels.
A clamp (K clamp) fitted to the rear of the GD100K immersion thermostat allows it to be attached to any vertical sided tank with a maximum wall thickness of 35mm for rectangular tanks, 30mm for circular tanks (300mm diameter) and a capacity of up to 50 litres.
Accessory options for GD100K
Polypropylene spheres
Polypropylene spheres are an alternative to lids for temperatures up to 100ºC, allowing easy access to vessels in the bath, and are particularly useful for tall vessels.

CG refrigerated immersion coolers Refrigerated coolers consist of a cooling coil connected by a flexible pipe to a refrigeration unit, which is housed in an outer case; immersion coolers extract heat continuously, with temperature control carried out by the bath’s control unit.
CW5 heat exchange coil: is designed to be attached to a supply of cooling tap water, or a refrigerated circulator.
