The Grant Optima™ GP200K is high-performance programmable digital thermostat with an exceptionally simple user interface. This allows fast set-up of multiple parameters through a powerful menu system and provides precision control for both routine and sophisticated temperature-controlled applications in the range of -50 to 200ºC. The unit includes an integral pump with multi-stage variable flow rate for more sophisticated circulating applications, a powerful heater for fast heat-up and memory capacity for five programs of 30 segments each.
The GP200K has RS232 communications capability and is programmable via PC. It can be used with
Labwise™, a software program to set all parameters, including programs, via the PC. Labwise™ also features real-time status windows, a graphic display of the controller's performance as a program is run, and allows data to be logged for future recall and analysis.
The GP200K 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 GP200K 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 GP200K
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.*

Note: The cooling coil may be continuously immersed in liquids up to 100ºC with the cooler switched off, and may be used to cool liquid down from 100ºC, but it is not designed for continuous operation above 40ºC.
Labwise™ software
Can be used to set all parameters, including programs, via the PC.
Labwise™ also features real-time status windows, a graphic display of the controller’s performance as a program is run, and allows data to be logged for future recall and analysis.
The Labwise™ software runs on a PC (Pentium II with Windows 95 or higher) and is suitable for use with the Grant Optima™ GR150 and GP200 controllers.
