OHAUS EXP423/AD Explorer EXP Precision Balance, 420 g Capacity, 1 mg Readability, AutoCal, Touchscreen

OHAUS EXP423/AD Precision Balance — 420 g at 1 mg Readability with Full Draftshield

Combining a 420 g capacity with 1 mg readability and a protective draftshield, the OHAUS EXP423/AD Precision Balance handles the full range of enclosed milligram-precision weighing tasks that fall between standard analytical and open-pan precision instruments. Pharmaceutical dispensaries, cosmetic labs, and nutraceutical manufacturers will appreciate the practical headroom of a 420 g ceiling paired with the protection of an enclosed chamber.

Key Features

• 420 g / 1 mg Capacity: Extends the milligram precision range well beyond 220 g, accommodating heavier sample vessels and bulk ingredient quantities in a single enclosed instrument.
• Anti-Static Glass Draftshield with Motorized Autodoors: Enclosed weighing chamber with motorized anti-pinch panels reduces airflow interference, protecting 1 mg measurements throughout extended use.
• Built-In Ionizer: Actively dissipates static charges that accumulate on weighing vessels, an important precaution with hygroscopic or electrostatically active materials.
• AutoCal Automatic Calibration: Temperature-compensated internal calibration maintains accuracy without scheduled manual calibration or operator intervention.
• 130 × 130 mm Stainless Steel Pan: Medium-sized platform accommodates standard weighing boats, Petri dishes, and small beakers typical of milligram-precision workflows.
• 1.5-Second Stabilization: Fast settling at 1 mg readability supports productive throughput in dispensaries and formulation suites.
• 15+ Built-In Weighing Applications: From check weighing and formulation to dynamic weighing and SQC, the EXP423/AD supports diverse analytical routines within a single instrument.

Detailed Overview

The OHAUS EXP423/AD Precision Balance addresses demand for milligram accuracy in heavier sample scenarios. With a 220 g counterpart (EXP223/AD) handling lighter work, the 423/AD extends that precision to 420 g—useful when vessel tare weights or larger ingredient quantities push totals past the 220 g threshold. The 1 mg typical repeatability and ±2 mg linearity maintain consistent performance across the full range. A USP minimum weight of 1.4 g (0.1% threshold: 1.4 g) reflects reliable accuracy for typical dispensary lots. Four-level user management, NTP time synchronization, and 100,000-entry audit logging make this model compatible with both ISO and GMP documentation requirements. Connectivity options—Ethernet, USB, RS232, and optional wireless—integrate the EXP423/AD directly into networked laboratory or production systems.

Applications

• Pharmaceutical dispensing of larger ingredient quantities at milligram accuracy
• Cosmetic and personal care formulation with heavier base materials
• Nutraceutical blending requiring enclosed milligram precision
• Gravimetric analysis with larger sample vessels or tare weights
• Food science ingredient weighing where vessel mass exceeds smaller balance ranges

Why Choose the OHAUS EXP423/AD?

Formulators and analysts who have outgrown 220 g milligram-precision balances without needing to step down to open-pan instruments will find the EXP423/AD precisely calibrated for the gap. An enclosed chamber, active ionization, and full audit capability keep quality standards intact. Order today to add 420 g milligram-precision capacity to your laboratory or dispensary.
