OHAUS AX422/E Adventurer Precision Balance, 420g Capacity, 0.01g Readability, Touchscreen, GLP/GMP

OHAUS AX422/E Adventurer Precision Balance — 420g Compact Precision with Color Touchscreen

A mid-range capacity combined with precise 0.01 g readability makes the OHAUS AX422/E Adventurer Precision Balance a versatile instrument for laboratories where sample masses fall predominantly between a few grams and 420 g. The Adventurer's full-color touchscreen and GLP/GMP compliance architecture are fully present here, making this model as capable in terms of software features as its higher-capacity siblings.

Key Features

• 420 g Capacity at 0.01 g Readability: A 420 g range covers the majority of common laboratory tasks — reagent weighing, small vessel tare, parts counting — with the precision resolution that good laboratory practice demands.
• Full-Color VGA Touchscreen: The Adventurer's high-resolution color display provides fast, visual navigation through the application library, making it more ergonomic than conventional button-based interfaces during multi-task laboratory sessions.
• Large 195 × 175 mm Pan for a 420 g Balance: An unexpectedly wide pan for this capacity class, accommodating standard 250 mL and 500 mL beakers comfortably without reducing the balance to a narrow-footed instrument.
• Three-Level GLP/GMP User Management: Distinct access privileges for administrators, supervisors, and operators enforce method integrity in shared laboratory environments and provide a verifiable audit trail.
• Triple Connectivity (USB Host, USB Device, RS232): All three ports are included as standard, enabling LIMS integration, USB drive data export, and legacy peripheral connection without accessories.
• 1.5-Second Stabilization: Quick result delivery suits applications involving many samples per session, from check-weighing production runs to multi-step formulation procedures.
• Broad Application Library via Touchscreen: Parts counting, percent weighing, dynamic weighing, totalization, statistics, and formulation are all accessible without additional purchases or software.

Detailed Overview

The OHAUS AX422/E holds ±0.02 g linearity and achieves 0.01 g typical repeatability across the full 420 g range, confirming that performance matches specification. The 10°C–30°C operating envelope is appropriate for climate-controlled analytical laboratories and precision production environments. Though it operates without an internal calibration mechanism, external calibration with certified masses is straightforward via the guided calibration menu. The in-use cover protects the balance between sessions, and the low-profile 100 mm housing fits under overhanging shelving that would obstruct taller touchscreen-equipped balances.

Applications

• General precision reagent weighing in chemistry, biology, and materials laboratories
• Parts counting for small electronic components in quality inspection workflows
• Check weighing during packaging or fill operations at 0.01 g tolerance
• Formulation and compounding of small to medium pharmaceutical batches
• Percent weighing for concentration calculations and dilution preparation

Why Choose the OHAUS AX422/E?

The AX422/E suits laboratories that need the Adventurer's touchscreen experience and compliance framework in a compact 420 g precision balance. Its broad pan, fast stabilization, and rich application suite make it suitable for daily analytical tasks requiring consistent 0.01 g results.
