主要特点

With multiple selectable home screens and on-screen help. the touch-screen controller features icons (with accompanying plain text terms) for Settings, Safety, Connect, Program, Home, Control, Time and Service. These let you set the desired pump speed, temperature display resolution, auto restart, display filter and other variables. Customizable safety features include High/Low limit and High/Low alarms with auto shut down. You can also enable or disable the Local Lock Out; when enabled a password entry screen will appear if the operator attempts to change the set point or access the Main Menu.

Calibration parameters include Priority, which means programs can be run using either a Time- or Temperature-based priority; Loop, which sets the number of times the program will run through the programmed steps; and Soak Temperature, the temperature the bath should be maintained at once the final step has been completed.

Two USB ports enable data logging onto a flash drive, as well as the ability to monitor or control the circulator using a personal computer. The controller may also be directly connected to a laptop or desktop computer via its Ethernet connection (or via a wired or wireless network) to let you control or monitor the bath in real time over the internet. RS-232 and RS-485 communications are also supported.

The circulating bath tank is made of stainless steel while the deck is chemical resistant, easy to clean and accommodates probes from 2 to 8 mm in diameter. Bath complies with DIN 12876-1 Class III safety requirements for use with flammable liquids. Advanced PID algorithms increase heat responsiveness and eliminate set point overshoot.
