Refrigerated/heated circulating bath is designed to duplicate the temperature fluctuations associated with beverage packaging, transportation. Suitable for performing accelerated aging studies, the 75-L bath features a -20° to +100°C working temperature range and ±0.005°C temperature stability. A touch-screen temperature controller displays temperature to 1/1000th of a degree and allows multiple thermal cycling options and programs. Communication options include USB-A and -B, Ethernet, RS232, addressable RS485, remote on/off, and external temperature control. A swiveling control head permits viewing of the temperature display anywhere within a 180° viewing radius, a corrosion and chemical resistant top plate remains cooler at high temperatures, and special environmental control technology reduces operational noise and energy consumption. Complies with DIN 12876-1 Class III safety requirements for use with flammable liquids.
