Linearity is ±± 0.003 g and stabilization time is 2 s, supporting high-throughput QC, formulation, and production weighing. An optional underfloor weighing hook enables density determination via liquid immersion. Built-in application modes include parts counting, percentage determination, tolerance weighing, extending the balance's utility across laboratory and industrial tasks. The integrated RS-232 interface connects to printers and LIMS; the 4 h warm-up ensures the tuning-fork sensor reaches full thermal stability before critical measurements.\u003c\/p\u003e\n  \n  \u003ch3\u003eApplications\u003c\/h3\u003e\n  \u003cul\u003e\n  \u003cli\u003eFormulation and dispensing in pharmaceutical and chemical QC laboratories\u003c\/li\u003e\n  \u003cli\u003eSample preparation and gravimetric analysis in R\u0026amp;D settings\u003c\/li\u003e\n  \u003cli\u003eParts counting and quality-control checkweighing in production environments\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \n  \u003ch3\u003eWhy Choose the KERN \u0026amp; SOHN EW 420-3NM?\u003c\/h3\u003e\n  \u003cp\u003eTeams working in laboratories and production teams needing 0.001 g resolution at 420 g capacity, the KERN \u0026amp; SOHN EW 420-3NM Precision Balance delivers proven tuning-fork performance with RS-232 connectivity and a comprehensive application suite.
