The Grant Instruments Optima GP200 series of digitally controlled stirred water baths and circulators provides outstanding performance for routine and sophisticated applications requiring accurate temperature control up to a maximum of 200 degC.

Grant Instruments GP200 series systems combine the powerful and versatile Grant Instruments Optima GP200 digital immersion thermostat with a choice of three economy plastic (P) tanks or five stainless steel (S) tanks with different capacities.

The Grant Instruments GP200 immersion thermostat incorporates Intelligent Control Optimisation (ICO) for adaptive intelligent PID temperature control and includes a powerful integral pump, making GP200 systems suitable both for immersing samples and circulating temperature controlled fluid to external devices. The temperature range and heater power are automatically limited according to the liquid type selected.

The GP200 control unit has a host of powerful and convenient programming features for optimum application flexibility. These include a convenient heater timer for early starts/late shutdowns, two programmable relays for switching external devices on/off, option for remote temperature monitoring, RS232 interface for PC communication and data collection, and memory capacity for five programs of up to 30 segments each.
