These compact analytical scales are designed for highly precise measurements of weight, with a built-in automatic internal adjustment function. This will automatically adapt to changes in temperature, ensuring that the accuracy of the scales is maintained at all times.
Kern's ALJ-AM Scales are best suited for measuring smaller objects up to a maximum weight of 250g (depending on the on the model purchased).
All models in the ALJ-AM series come as standard with a three-door glass draught shield, protecting the material being measured from outside factors.
The Kern ALJ-AM Verifiable Analytical Balances differ from their sister products, the Kern ALJ-A Single-Range Analytical Balances, in that they can be verified in accordance with EU permissible tolerances. An OPTIONAL Kern verification can be purchased with these balances, please contact our sales team for further information or to add this to an order. According to the EU directive 2014/31/EEC, all member states must calibrate/ verify scales that are to be used in the following capacities:
There are a number of Kern accessories compatible with the Kern ALJ-AM Analytical Balances, including Kern calibrations and verifications. For a quick overview of the accessories available for Kern ALJ-AM Analytical Balances, please see the table below.
