GD100 series - digital control

The Grant Optima™ GD100 series of stirred water baths and circulators with digital control provides excellent value for money for straightforward applications requiring accurate temperature control up to a maximum of 100ºC.

The Grant GD100 immersion thermostat incorporates Intelligent Control Optimisation™ (ICO) for adaptive intelligent PID temperature control.

Grant GD100 series systems offer a choice three economy plastic (P) tanks or five stainless steel (S) tanks with different capacities combined with the Grant Optima™ GD100 digital thermostat for accurate temperature control.

  • Simple-to-use rotor plus two keys provide access to the interactive interface for fast, accurate set-up
  • Clear digital display for instant reassurance - easy to read from a distance
  • Visual alarm - alerts you when your attention is required
  • Operating setpoint plus 3 adjustable preset temperatures for convenience
  • User calibration facility for optimum accuracy at the required operating temperature
  • Low liquid protection by float switch
  • Cooling/heating range: ambient +5 to 99ºC with plastic (P) tank, or 0 to 100ºC with stainless steel (S) tank
  • Stability ± 0.02ºC

Note: Alternatively, the Grant Optima™ GD100 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.
