OHAUS EXP1203/AD Explorer EXP Precision Balance, 1,200g Capacity, 1mg Readability, AutoCal, Touchscreen

OHAUS EXP1203/AD Precision Balance — 1,200g with Built-In Ionizer, Auto Doors, and 1mg Resolution

Static charge on plastic containers and film wrapping is a silent source of weighing error at the milligram level. The OHAUS EXP1203/AD Precision Balance directly addresses this with a built-in ionizer that neutralizes electrostatic charge before it affects readings—combined with a 1,200 g capacity, 1 mg readability, motorized anti-pinch auto doors, and AutoCal calibration on the flagship EXP platform.

Key Features

• Built-In Ionizer: Continuously neutralizes electrostatic charge around the weighing chamber, eliminating one of the most common but least visible sources of milligram-level measurement error—particularly critical when weighing lightweight plastic containers or fine powders.
• Anti-Pinch Motorized Auto Doors: Safety-protected motorized draftshield doors open and close automatically without hand contact, preventing vibration disturbance and protecting the operator's fingers during high-frequency sample loading.
• 1mg Readability over 1,200g Capacity: A broader range than most 1 mg precision models accommodates larger samples and heavier containers while maintaining full milligram resolution throughout.
• AutoCal Automatic Calibration: Thermal monitoring triggers internal recalibration automatically, maintaining ±2 mg linearity across the 1.2 kg range without interrupting measurement workflows.
• 7-Inch 16.7M Color TFT Touchscreen: The large, glass-overlaid display surfaces all application data, calibration status, and connectivity settings clearly, improving efficiency during extended laboratory sessions.
• Multi-Port Connectivity with Optional Wi-Fi/Bluetooth: USB-A (×2), USB-B, USB-C, Ethernet, and RS232 are standard; wireless options extend data capture to tablet-based LIMS and mobile quality-management platforms.
• 4-Level User Management and 100,000-Entry Log: Role-based access tiers and an extensive internal audit trail satisfy data integrity requirements in GLP, GMP, and ISO-certified laboratory environments.

Detailed Overview

The OHAUS EXP1203/AD Precision Balance is purpose-designed for analytical and precision laboratory workflows where static charge, sample contamination, and measurement throughput all compete for attention. The integrated ionizer operates passively, requiring no separate device or procedure—it simply removes the electrostatic interference that causes unexplained drift in milligram readings. Motorized anti-pinch doors add a safety and precision dimension to sample loading: each door cycle is smooth, vibration-free, and consistent. The 1.5-second stabilization time and AutoCal mechanism deliver confident readings even in laboratories where temperature swings between morning and afternoon. The 130 × 130 mm stainless steel pan accommodates standard analytical vessels, and the draftshield's anti-static glass provides additional protection against charge-related error. With a 3,000-entry application library and NTP time synchronization, the EXP1203/AD supports both rapid method recall and accurate batch documentation.

Applications

• Pharmaceutical powder weighing where static charge on containers distorts milligram readings
• High-frequency pipette calibration and analytical sample preparation
• Polymer and film sample weighing susceptible to electrostatic build-up
• GLP/GMP laboratory workflows requiring auto doors, ionizer protection, and audit logging

Why Choose the OHAUS EXP1203/AD?

Analytical chemists and quality laboratory technicians who weigh electrostatically sensitive materials—lightweight plastics, fine powders, or film-wrapped samples—will find the OHAUS EXP1203/AD Precision Balance's built-in ionizer a practical solution to a common but underappreciated measurement problem. Paired with motorized auto doors and AutoCal on the flagship EXP platform, it addresses multiple sources of milligram-level error simultaneously. Add to cart to equip your analytical bench with ionizer-protected, auto-door precision at the 1.2 kg range.
