Grant Optima refrigerated circulating baths, TX150 R series

Grant Optima^TM refrigerated circulating baths, TX150 R series
The Grant Optima^TM TX150 R series of digitally controlled refrigerated circulating baths provides outstanding performance for routine and sophisticated applications requiring accurate temperature control in the range of -47 to 100°C.
Grant TX150 R series refrigerated systems combine the powerful and versatile Grant Optima^TM digital heating circulator TX150 with a choice of five rugged stainless steel refrigeration units with different facilities and working volumes. The Grant Optima^TM TX150 is a high-performance programmable digital heating circulator with an exceptionally simple user interface. This allows fast set-up of multiple parameters through a powerful menu system and provides sophisticated control for temperature-controlled applications.
The TX150 has USB connectivity to a PC or laptop. It is programmable with Labwise^TM, a software program to set all parameters, including programs, via the PC. Labwise^TM also features real-time status windows, a graphic display of the controller's performance as a program is run, and allows data to be logged for future recall and analysis.
