WTC precision balances enable fast and accurate determination of mass in laboratory. 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. Communication interfaces: RS232, USB type A, USB type B. The interfaces enable cooperation with peripheral devices, e.g. printer, computer, USB flash drive. The WTC balances feature real-time clock and ALIBI memory.
