354 3. Analytical measurement and testing Balances/Precision balances GENERAL CATALOGUE EDITION 20 E & OE. Precision balance PNS/PNJ The new standard in the laboratory with robust tuning fork weighing system. - Only PNJ: Automatic internal adjustment, guarantees high degree of accuracy and makes the balance independent of its location of use. Ideal for mobile applications which require verification, such as ambulatory gold and jewellery purchasing - Only PNS: Adjusting program CAL for quick setting of the balance accuracy using an external test weight - High-quality tuning fork measuring system for steady weight values and continuous weighing - Capacity display: A bar lights up to show how much of the weighing range is still available - Precise counting: The automatic reference weight optimisation of reference weight gradually improves the average piece weight value - Totalising of pieces when counting - Compact size, practical for small spaces - Large stainless steel-weighing plate, removable - Large glass draught shield with 3 sliding doors for easy access to the items being weighed, for models with weighing plate size diam. 140 mm, weighing space (W x D x H): 172 x 171 x 160 mm - Large LCD display, digit height 16.5 mm - Permissible ambient temperature 5 °C/35 °C Kern & Sohn 1 6.270 591 2 7.643 634 1 2 Type Plate dimensions External dimensions (W x D x H) Capacity Readability Reproducibility Linearity Weight PK Cat.

Removable metal cover with pipette opening. Weighing space 150mm dia., height 60mm - count/weight switchover at the press of a button - precise counting. The automatic optimisation of reference weight gradually improves the average value of the piece weight. The automatic optimisation of reference weight gradually improves the average value of the piece weight - weighing with tolerance range Input of an upper/lower limit value. A visual signal assists with portion division, dispensing or grading - percentage determination makes it possible to store a given weight value (100%) and to determine deviations from this target value in % - density determination of liquids and solids with immediate display of the density on the display - pre-Tare function for manual deduction of a known container weight.
