Precision balances enable fast and accurate determination of mass in laboratory and industry. The devices are equipped with an internal battery which allows their operation in places where there is no access to the mains.
The balance features a stainless steel weighing pan, and a backlit LCD guaranteeing clear weighing result presentation. They also have an option of automatic internal adjustment. Communication interfaces: 2×RS232, USB type A, USB type B. The interfaces enable cooperation with peripheral devices, e.g. printer, computer, USB flash drive, additional display. The WLC balances feature real-time clock and ALIBI memory. Optionally, they can be equipped with 4 IN / 4 OUT.
Internal rechargeable cell comes standard with WLC C/2 series balance! Internal adjustment/calibration system!
