The Unico Digital Differential Counter (#L-BC9D) is an eight key unit with a totalizer window.
Warranty: 1 Year.
The newer Digital model allows you to use the subtract function to remove an unwanted entry, removing the need to start over with mistakes. It was designed with the traditional user in mind. You will not have to re-learn the keys.
Unico Differential Counters have been time tested for decades in the clinical laboratory.
