The Grant Optima™ GD100 R series of refrigerated baths and re-circulators with digital control provides excellent value for money for straightforward applications requiring accurate heating and cooling in the temperature range of 0 to 100°C.
The Grant GD100 immersion thermostat incorporates Intelligent Control Optimisation™ (ICO) for adaptive intelligent PID temperature control and can be combined with four of Grant's refrigeration units.
- 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
- Choice of four refrigerated (R) tanks with different facilities, working volumes and cooling capacities
- Cooling/heating range: 0 to 100°C
- Stability ± 0.1°C
Note: The refrigeration unit can be switched off indepedendently of the thermostat to allow heating only applications. All the refrigeration base units can be used up to a maximum temperature of 100°C.
The Grant Optima™ GD100 R series of refrigerated baths and re-circulators provides a choice of four systems with different facilities, stainless steel tank capacities and cooling power to suit different applications.
The Grant combined tank/refrigeration units are robustly constructed for long life and efficient and reliable operation.
