The new benchtop spectrophotometer that succeeds the DR3900, with a 10-inch screen and built-in test diagnostics.
The DR4900 keeps the proven core of the DR3900 and adds a 10-inch touchscreen and a modern interface that shortens training and speeds up routine work. When you use LCK cuvette tests, it checks the temperature and turbidity of each test and alerts you when either is out of range, which prevents common errors before they reach your report.
