The Grant Instruments Optima GR150 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 150 degC.

Grant Instruments GR150 series systems combine the powerful and versatile Grant Instruments Optima GR150 digital immersion thermostat with a choice of three economy plastic (P) tanks or five stainless steel (S) tanks with different capacities.

The Grant Instruments GR150 immersion thermostat incorporates Intelligent Control Optimisation (ICO) for adaptive intelligent PID temperature control and includes a powerful integral pump, making GR150 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 GR150 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, a programmable relay for switching external devices on/off, option for remote temperature monitoring, RS232 interface for PC communication and data collection, and memory capacity for one program of up to 30 segments.
