KERN EWJ Precision Balance 300-3/300-3H

The EWJ  precision balance 300-3/300-3H from KERN convinces with efficient and accurate weighing, with practical additional functions. The modern design and the large weighing surface make the scale ideal for any weighing in the laboratory. The glass protection prevents drafts and thus ensures accurate results without falsification. The determined result can then beread off in very small numerical increments . Afterwards, the easy-care material can beeasily disinfected and cleaned.

Practical additional functions of the EWJ Precision Balance 300-3/300-3H

For precise weighing results and as a support in everyday laboratory work, the balance has various additional functions.

With the tare function , the respective tare weight of preloads can be determined and tared in advance. This function is suitable in the laboratory for glassware and reagent holders, for example. Only the tared weight is then subsequently shown on the display.

The internal automatic calibration/adjustment system also enables high accuracy and practical independence from location. Every 2 hours the automatic calibration is activated and the test weight is checked.
