Electronic Weighing Counting Instrument

The Electronic Weighing Counting Instrument (Model AO919C) is a high-precision intelligent integrated weighing and counting terminal developed by Jiangsu Jutian (J-SKY), built on over 20 years of core technological accumulation in the weighing industry.It is specially designed for industrial production and warehouse inventory management scenarios.

Targeting core industry pain points such as low efficiency, large errors, difficult batch control, and weak data traceability in traditional manual counting, this instrument integrates precise weighing, intelligent counting, batch management, data storage, and multi-device linkage.It can seamlessly match various industrial platforms and serves as core equipment for digital production and inventory control in electronics manufacturing, hardware processing, pharmaceutical packaging, retail and trade industries.

Core Functions & Performance Highlights

Top-Tier Weighing Accuracy

Equipped with an industrial-grade high-precision weighing acquisition module, reaching 1/15 000 maximum accuracy and 600 000 internal resolution.It delivers stable and accurate counting even for miniature components as light as 0.01g per piece (such as SMD parts and micro fasteners), fundamentally eliminating counting deviations.

Intelligent Multi-Batch Management

Stores up to 100 groups of material weight upper/lower limit thresholds as standard.Built-in pass/fail dual-mode warning system, connectable to an external tri-color audible and visual alarm light.Preset parameters can be recalled with one click during production line changeover, eliminating repeated calibration and greatly improving efficiency for multi-variety, small-batch production.

Full-Scenario Professional Functions

Supports free unit switching: kg / g / lb / oz / pcs.Standard functions include intelligent taring, dual gross/net weight display, data accumulation, automatic zero tracking, single/multi-point calibration, low voltage reminder, and auto power off.Adapts to static inventory counting, dynamic production line inspection, cumulative dosing control and other working modes.

Industrial-Grade Reliable Design

High-impact ABS engineering plastic housing + industrial-grade mechanical keys, wear-resistant and easy to maintain, suitable for harsh workshop environments.32mm extra-large high-brightness LED digital tube for clear readings in bright or dim conditions.AC/DC dual power supply with built-in 6V/4Ah large-capacity battery, ensuring stable operation even during unexpected power outages.

Strong Expansion & Customization

Optional full-range communication interfaces: RS232 / RS485 / Bluetooth / Ethernet / WiFi / USB storage / 4–20mA analog output.Seamlessly connects to barcode scanners, thermal printers, external large screens, ERP / MES systems.Supports full customization of platform size, material, and dedicated weighing application software to meet non-standard on-site requirements.
