OHAUS EXP223/AD Explorer EXP Precision Balance, 220 g Capacity, 1 mg Readability, AutoCal, Touchscreen

OHAUS EXP223/AD Precision Balance — 220 g at 1 mg Readability with Draftshield

Bridging the gap between high-capacity precision and milligram sensitivity, the OHAUS EXP223/AD Precision Balance weighs up to 220 g with a 1 mg resolution and a full anti-static glass draftshield. The enclosed weighing chamber suits labs where drafts or dust could compromise results, and the stainless steel pan accommodates the size of most analytical weighing vessels while remaining large enough for routine formulation tasks.

Key Features

• 1 mg Readability with Draftshield: Milligram-level precision in an enclosed weighing chamber protects sensitive measurements from ambient air movement and contamination.
• 220 g Maximum Capacity: Covers the full range of small analytical samples, reference standards, and laboratory consumables without requiring a second instrument.
• Motorized Anti-Pinch Autodoors: Electrically actuated draftshield panels open via touchless proximity sensors, minimizing handling and protecting samples.
• AutoCal Automatic Internal Calibration: Temperature-responsive self-calibration activates when needed, ensuring measurement integrity without scheduled downtime.
• Built-In Ionizer: Continuously dissipates static charge from the pan surface and sample, a meaningful advantage when weighing lightweight films, powders, or granules.
• 1.5-Second Stabilization Time: Rapid settling enables high-throughput operation while maintaining 1 mg repeatability throughout the day.
• 5.1-Inch × 5.1-Inch Pan: The 130 × 130 mm platform comfortably seats medium weighing boats, small beakers, and sample cups common in analytical workflows.

Detailed Overview

The OHAUS EXP223/AD Precision Balance occupies a practical niche: it offers draftshield protection and milligram accuracy at a 220 g ceiling, making it useful for both analytical chemistry and precision production tasks. The USP minimum weight of 1.4 g at 0.1% tolerance indicates it handles a wide span of practical sample sizes reliably. Connectivity options—including Ethernet, RS232, USB-A ×2, USB-B, and USB-C—allow direct integration with laboratory printers, computers, and network data systems, with optional Wi-Fi and Bluetooth for wireless workflows. The motorized leveling system removes the uncertainty of bubble adjustment, and the 7-inch color touchscreen presents data clearly even in challenging lighting conditions. With 15 application modes built in, analysts can switch from check weighing to formulation to percent weighing with a few screen taps.

Applications

• Small-scale pharmaceutical formulation and API dispensing
• Gravimetric analysis requiring draftshield protection
• Reference standard preparation and verification
• Cosmetics and fragrance ingredient weighing
• Educational laboratory experiments requiring milligram precision
