The Kern ALJ-A Single-Range Analytical Balances can be used to weigh a variety of items accurately. They include an automatic internal adjustment function which will alter the balance in order to maintain its accuracy. It will activate when a temperature difference of equal to or greater than 1.2°C is detected. Alternatively, it may be programmed to verify and/or adjust the balance’s accuracy every three hours. In addition to this, the Kern ALJ-A Single-Range Analytical Balances include an electromagnetic force compensation function which is also optimised to maintain the instruments’ accuracies.
Measurements are indicated on the Kern ALJ-A Single-Range Analytical Balances’ backlit, LCD displays with a digit height of 17mm. The user is able to switch between measurement units at the touch of a button. He/she can also program the Kern ALJ-A Single-Range Analytical Balances to include upper and lower limits; if either of these limits is breached the balances will alert the user via a visual and audible alarm.
Moreover, the balances include a Hold function which allows them to determine an average weight measurement when weighing conditions are unsteady/ unstable. Other functions present on the Kern ALJ-A Single-Range Analytical Balances include:
When using the recipe function it is possible to send the total weight of the recipe to print (when used with a compatible Kern printer – NOT included). It is also possible to send selected weight measurements to print; these values are printed with the date and time. The Kern ALJ-A Single-Range Analytical Balances include an RS-232 interface in order to facilitate a connection between the balance and the printer.
Accessing the instruments’ functions and changing between measurements and measurement units is made easy as a result of the Kern ALJ-A Single-Range Analytical Balances’ ergonomic keypads which have been optimised for both right- and left-handed users.
Other ergonomic features include the balances’ compact size and large glass draught shields with three sliding doors; the glass shield protects the items-under-investigation from contamination whilst preserving the user’s view and ensuring that he/she has easy access to the enclosed objects. These instruments are also supplied with protective working covers.
The Kern ALJ-A Single-Range Analytical Balances are ergonomic, comprehensive, accurate weighing instruments.
