GR150 series - digital high performance

The Grant 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 150ºC.

Grant GR150 series systems combine the powerful and versatile Grant 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 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.

  • Dual display: bright LED for temperature display plus 2-line 16 character LCD for easy programming
  • Twin heaters, 2kW heater power for fast heat up
  • Pt1000 external probe socket for remote monitoring
  • Powerful integral pump, maximum flow 17L/min
  • Variable high and low temperature alarm settings - configurable to switch a relay
  • Choice of 5 operator languages
  • Optional Labwise™ PC software for program set-up, data logging and real-time graphing
  • Maximum cooling/heating range (dependent on tank size): ambient +5 to 99ºC with plastic (P) tank, or -15 to 150ºC with stainless steel (S) tank
  • Stability ± 0.005ºC

Note: Alternatively, the Grant Optima™ GR150 immersion thermostat can also be used to regulate the temperature in vessels other than Grant tanks. Such vessels must have vertical sides and a maximum wall thickness of 35 mm for rectangular tanks, 30 mm for circular tanks (300 mm diameter) and a capacity of up to 50 litres. The control unit is attached to other vessels by means of a clamp.
