The Grant Optima™ range consists of either general purpose or advanced performance thermostats combined with double walled plastic baths. Baths are easy to clean and available in three sizes –5, 12 and 18 litres. They offer a cost effective solution for applications requiring accurate temperature control. Can be used up to 99 °C.

• Stirred circulation within the tank ensures excellent temperature stability and uniformity
• Fixed and adjustable over temperature cut-out, clear alerts and alarms
• Rotary dial and function key controls
• Highly visible LED temperature display
• TC120 integrated pump for external circulation
• Intelligent design, robust construction
• Excellent temperature control

General purpose thermostats: T100 and TC120:
Digital microprocessor controlled T100 and TC120 thermostats feature an easy to use rotary dial and two function keys for quick temperature setting and menu navigation. Units feature a bright, easy to view 4-digit display, three programmable temperature presets, low liquid protection, fixed over-temperature cut-out, visual (T100) or audible (TC120) alarm, countdown timer (TC120) and user calibration facility for optimal accuracy.

Advanced thermostats: TX150 and TXF200:
TX150 and TXF200 thermostats feature a full colour QVGA TFT screen displaying actual and set temperature and clear status icons. The QVGA TFT screen in combination with the easy to use dial and function keys allows rapid navigation through the intuitive menu system. Both units have an RS232 and USB interface and can be programmed via remote PC or laptop using Grant’s versatile Labwise™ software (optional). Additional features include countdown timer, adjustable over-temperature cut-out, visual, audible and programmable high and low temperature alarms. The TX150 has the capacity to store 1 program with 30 segments. The TXF200 can also be programmed via the user interface and can store up to 10 programs containing 100 segments. The programming interface includes set target temperature with a choice of time to target temperature or temperature ramp speed and an additional programmable relay for on/off control of ancillary equipment or refrigeration units.
