Optima thermostatic controllers from Grant are suitable for most heating tasks in laboratories. Sophisticated electronics and the latest materials combine to ensure optimum performance, accuracy and stability.
Model TC120 features:
- PID control, soft-touch rotary selector and push-button setting
- LED display and simple user interface
- Fault indication and visual alarm
- User-adjustable overtemperature cut-out
- Low liquid protection by float switch
With an injection moulded case, timer function from 0 to 9999 minutes, heater, external circulation pump and two connector plates with outlets for 6mm or 11mm tubing bores, stirrer and Pt1000 temperature sensor projecting down into the liquid. For 230V 50Hz single phase supplies. Each controller is supplied without clamp. An accessory clamp (BJ180-95) allows the controller to be used with almost any type of vessel where it can be attached to the vessel wall. When the controller is to be used with Optima bath tanks the clamp is unnecessary as a bridge plate is provided

*A lid or layer of polypropylene spheres must be used when operating between 60°C and 100°C, and is recommended for use below room temperature. Above 100°C, a lid must always be used. Minimum operating temperature without accessory cooling is ambient plus 5°C, except in the 5 litre tanks, in which it is ambient plus 15°C. Minimum and maximum temperatures achievable are dependent upon the tank insulation and the minimum operating temperature depends on the accessory immersion cooler selected.
