OHAUS EX423N Explorer Precision Balance, 420g Capacity, 1mg Readability, AutoCal, NTEP Certified

OHAUS EX423N Explorer Precision Balance — 420 g Capacity, 1 mg Resolution, NTEP-Ready Touchscreen

Precision work at milligram resolution across a generous 420 g range is the defining strength of the OHAUS EX423N Explorer Precision Balance. Pairing automatic internal calibration with a 5.7-inch full-color VGA touchscreen and NTEP certification, it delivers the accuracy and compliance features demanded by professional laboratories and regulated commercial operations.

Key Features

• 420 g Capacity at 1 mg Readability: A wider working range than most analytical balances at this resolution, supporting larger sample loads without sacrificing milligram precision.
• Full-Color 5.7-Inch Touchscreen: User-adjustable brightness and intuitive touch navigation streamline access to a comprehensive suite of weighing applications.
• AutoCal Automatic Calibration: The balance self-calibrates when environmental conditions shift, removing the need for manual calibration cycles and reducing downtime.
• NTEP and Measurement Canada Approval: Certified for legal-for-trade use, making the EX423N suitable for compliance-driven contexts in pharmaceutical and commercial testing.
• Included Draftshield: Encloses the 130 mm stainless steel pan to guard against air movement that could skew milligram-level readings.
• Dual Built-In Communication Ports: RS232 and USB enable data export to laboratory information systems, printers, and computers without additional hardware.
• Comprehensive Application Modes: From parts counting and formulation to SQC, dynamic animal weighing, and ingredient costing — over 15 modes cover diverse lab workflows.

Detailed Overview

The EX423N occupies a distinct niche: a precision balance that spans milligram accuracy and a capacity more typical of mid-range instruments. This makes it well-suited for labs that alternate between careful small-sample work and larger batched measurements, avoiding the need for two separate balances. Typical repeatability of 0.001 g and linearity within ±0.002 g support reliable, reproducible results across the working range. The larger 130 mm pan compared to the analytical EX224N allows bigger containers and multi-component samples. Ethernet connectivity is available as an accessory for labs requiring network-integrated data logging. The removable draftshield and pan simplify cleaning, while the GLP/GMP output format ensures documentation meets regulatory requirements.

Applications

• Compounding and pharmaceutical QC where milligram precision meets higher batch weights
• Food and beverage analytical testing under regulated trade certification
• Research and development formulation requiring a broad capacity-to-resolution ratio
• Educational analytical chemistry requiring both accuracy and durability under student use
