Analytical balance ABP

This new generation of analytical balances combines the highest level of precision with large weighing capacities. Thanks to the new Single-Cell Generation, the weighing result is displayed in a fraction of the time with comparable models. The multifunctional weighing plate (only for models with readability 0.01 mg) minimises the effect of air currents in the weighing chamber and therefore significantly improves the stabilisation time and repeatability. In addition samples, sample paper, PCR tubes and microcentrifuge tubes can be easily fixed and weighed.OLED displayNavigation pad for super quick navigating through the menusAutomatic internal adjustment in the case of a change in temperature ≥ 1 °C or timecontrolled every 4 h, guarantees high degree of accuracy and makes the balance independent of its location of useThe minimum weight of sample can be manually stored in the balance or automatically calculated, with warning message when the weighing is below this valueDosage aid: High-stability mode and other filter settings can be selectedSimple recipe weighing and documenting with a combined tare/print functionMenu language DE, GBAutomatic data output to the PC/printer each time the balance is steadyUSB data interfaces and RS-232Large glass draught shield with 3 sliding doors for easy access to the items being weighedScope of supply:Analytical balance, protective working cover, universal mains adapter
