KERN & SOHN EW 220-3NM EW Precision Balance, 220 g Capacity, 0.001 g Readability, RS-232

KERN & SOHN EW 220-3NM Precision Balance — 220 g Capacity, 0.001 g Readability

For QC labs needing high-resolution weighing at 220 g, the KERN & SOHN EW 220-3NM Precision Balance delivers 0.001 g readability with a tuning-fork sensor and integrated RS-232. The 180×235×75 mm plastic housing fits comfortably on standard laboratory benches, and the removable stainless steel weighing plate cleans quickly between sample runs.

Key Features

• 220 g at 0.001 g readability: 220.000 resolution enables precise dosing, formulation, and QC weighing across the full range of the KERN & SOHN EW 220-3NM.
• Tuning-fork weighing sensor: KERN's electromagnetic tuning fork technology achieves a 2 s stabilization time and resists thermal drift, reducing recalibration frequency on high-volume benches.
• Integrated RS-232 interface: Standard serial output connects the KERN & SOHN EW 220-3NM to PCs, printers, and LIMS for real-time, GLP-compliant data capture.
• Parts counting and percentage determination: Count pieces for kitting and inventory; calculate proportional weights against a reference for recipe and QC formulation tasks.
• Tolerance weighing: Configure upper and lower weight limits to trigger visual alerts when samples fall outside specification, enabling faster QC sorting.
• Level indicator and adjustable feet: A built-in bubble level and four adjustable feet confirm correct installation on any bench surface for repeatable results with the KERN & SOHN EW 220-3NM.

Detailed Overview

The KERN & SOHN EW 220-3NM Precision Balance is a tuning fork-sensor balance at 220 g capacity and 0.001 g readability in a 180×235×75 mm plastic housing. Linearity is ±± 0.002 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 120 min warm-up ensures the tuning-fork sensor reaches full thermal stability before critical measurements.

Applications

• Formulation and dispensing in pharmaceutical and chemical QC laboratories
• Sample preparation and gravimetric analysis in R&D settings
• Parts counting and quality-control checkweighing in production environments
