Shanghai Hengping JY Series Precision Electronic Balance (0.01 g readability)

Overview

The Shanghai Hengping JY Series Precision Electronic Balance is an entry-level yet robust analytical weighing instrument engineered for consistent accuracy and operational reliability in non-regulated or general-purpose laboratory, educational, and industrial environments. Built around a high-stability strain gauge load cell and integrated single-chip microprocessor architecture, the JY series delivers stable mass measurement through real-time digital signal processing and automatic zero-tracking compensation. Its 0.01 g readability (on select models including JY1002 through JY20002) meets the performance requirements of routine quality control, formulation preparation, sample portioning, and educational experiments where Class II or III precision per OIML R 76-1 is sufficient. The balance operates on standard AC mains power and features a compact, low-profile chassis optimized for benchtop space efficiency—making it suitable for multi-user teaching labs, small-scale production lines, and field-deployable QA stations.

Key Features

• High-contrast LED display with intuitive digit grouping for rapid visual verification of mass readings
• External calibration capability using certified standard weights—fully compliant with ISO/IEC 17025 traceability workflows when documented appropriately
• Auto-tare function with full-range tare capacity and memory retention across power cycles
• Counting mode with preset piece-weight averaging and statistical count stability assessment
• Unit conversion between grams, ounces, carats, and other common mass units—user-selectable without firmware modification
• Integrated overload protection circuitry and real-time fault diagnostics to prevent sensor damage and ensure long-term repeatability
• Removable three-sided plastic draft shield (left, right, and top access) designed for easy cleaning and compatibility with moderate airflow conditions
• Compact footprint (225 × 185 × 55 mm) and lightweight construction (2.0–2.3 kg) enabling flexible placement and portability within shared lab spaces

Sample Compatibility & Compliance

The JY series accommodates a broad range of solid and granular samples—including powders, tablets, reagents, and mechanical components—within its 100 g to 6000 g maximum capacity range. The stainless steel weighing pan (Φ110 mm to 170 × 185 mm depending on model) resists corrosion from mild solvents and routine handling wear. While not certified for GLP/GMP-regulated environments requiring 21 CFR Part 11-compliant audit trails or internal calibration records, the balance supports basic metrological practices aligned with ISO 9001 internal calibration procedures and ASTM E1153 guidance for non-critical weighing tasks. Its external calibration protocol allows integration into facility-wide equipment management systems where user-defined calibration intervals and documentation are maintained manually or via LIMS.

Software & Data Management

The JY Series operates as a standalone instrument without embedded PC connectivity or proprietary software. All functions—including counting, unit conversion, and tare—are executed locally via front-panel key inputs. No drivers, SDKs, or data logging interfaces are provided; however, the balance’s stable analog-to-digital output architecture ensures compatibility with third-party RS-232 or USB-to-serial adapters (when externally added) for basic ASCII-formatted weight streaming to spreadsheets or custom acquisition scripts. For laboratories requiring formal data integrity, manual transcription or periodic snapshot recording remains the recommended practice per ALCOA+ principles under non-GxP contexts.

Applications

• Academic instruction in chemistry, physics, and materials science laboratories
• Raw material receipt inspection and batch sampling in food, pharmaceutical, and chemical manufacturing support roles
• Formulation and blending operations in R&D pilot plants where ±0.01 g resolution satisfies process tolerance thresholds
• Inventory management and parts counting in electronics assembly and mechanical workshops
• Calibration verification of volumetric glassware and pipettes using water density-based mass-to-volume correlation
• Environmental sample preparation in field labs where portability and low power consumption are prioritized over regulatory compliance

FAQ

What is the minimum readability of the JY Series balances?
The JY1002, JY2002, JY3002, JY5002, JY6002, JY10002, and JY20002 models offer 0.01 g readability; JY2001, JY12001, JY40001, and JY60001 models provide 0.1 g readability.
Does the JY Series support internal calibration?
No—calibration is performed exclusively via external standard weights. No built-in motorized or reference mass mechanism is included.
Is the draft shield included with all models?
Yes—each unit ships with a removable three-sided plastic draft shield compatible with left-, right-, and top-access configurations.
Can this balance be used in a regulated GMP environment?
It is not designed for GMP or FDA-regulated applications requiring electronic audit trails, password-protected configuration, or automated calibration reporting per 21 CFR Part 11.
What power source does the JY Series require?
Standard AC input: 220 V ±10 %, 50 Hz, with power consumption ≤3 VA—no battery operation is supported.
