SUNNY HENGPING YP20K-1 Advanced Precision Balance

Overview

The SUNNY HENGPING YP20K-1 is a high-reliability, general-purpose precision balance engineered for routine mass measurement tasks in quality control laboratories, educational institutions, industrial packaging lines, and inventory management environments. Operating on electromagnetic force compensation principle, it delivers stable and repeatable readings across its full 30 kg capacity range with 0.1 g readability. Designed for robust daily use, the YP20K-1 features a rigid aluminum alloy base, reinforced stainless-steel weighing pan, and intelligent environmental compensation algorithms to mitigate drift caused by minor temperature fluctuations or air currents. Its rapid stabilization time of ≤2 seconds ensures efficient throughput without compromising measurement integrity—critical in high-volume sample processing workflows where operator efficiency directly impacts batch release timelines.

Key Features

• Full-range tare and zero functions enabling precise net weight determination regardless of container mass.
• Integrated overload and underload detection with clear visual alerts on the 128×64 dot-matrix LCD display.
• Dual power operation: compatible with both AC adapter (100–240 V, 50/60 Hz) and DC battery input (optional), supporting field or mobile lab deployment.
• Standard RS232 serial interface compliant with EIA/TIA-232-E specifications for direct connection to PCs, LIMS, or statistical process control (SPC) software.
• Seven selectable weighing units—including grams (g), kilograms (kg), ounces (oz), pounds (lb), carats (ct), pennyweights (dwt), and grains (gn)—facilitating cross-functional data exchange in multi-departmental settings.
• Counting mode with automatic average piece weight calculation, supporting batch quantity verification for uniform parts (e.g., screws, tablets, electronic components).
• Self-diagnostic system continuously monitors sensor status, internal voltage levels, and calibration integrity; error codes are displayed per ISO/IEC 17025 traceability guidelines.

Sample Compatibility & Compliance

The YP20K-1 accommodates diverse sample forms—from bulk powders and granular solids to packaged goods and small assemblies—within its 285 × 235 mm stainless-steel pan. Its open-frame design allows easy placement and removal of containers up to 150 mm in height. The balance meets essential metrological requirements defined in OIML R76-1 (2017) for Class III non-automatic weighing instruments and conforms to JJG 1036–2022 (People’s Republic of China National Verification Regulation for Electronic Balances). While not certified for GLP/GMP-regulated quantitative analysis requiring audit trails, it supports basic documentation workflows via RS232 output compatible with 21 CFR Part 11-compliant third-party data acquisition systems when paired with appropriate validation protocols.

Software & Data Management

No proprietary software is bundled; however, the RS232 interface enables seamless integration with industry-standard platforms including LabX (Mettler Toledo), WinCT (A&D), or custom Python/Excel-based data loggers using standard ASCII transmission protocol (9600 baud, 8N1). All transmitted data include timestamp (when host system provides), gross/net/tare identifiers, unit code, and status flags (e.g., “ST” for stable, “OL” for overload). Optional thermal printer support allows hard-copy generation of weigh records aligned with internal SOPs for raw material receipt or finished goods inspection.

Applications

• Raw material receipt inspection in food, pharmaceutical, and chemical manufacturing facilities.
• Batch formulation and ingredient dispensing in R&D labs and pilot-scale production.
• Inventory control and warehouse reconciliation for hardware, electronics, and medical device components.
• Student laboratory exercises in physics, chemistry, and engineering curricula requiring reproducible mass measurement.
• Quality assurance checks during packaging line setup and changeover verification.
• Field-based agricultural extension services conducting soil sample dry-weight analysis.

FAQ

Is the YP20K-1 suitable for ISO/IEC 17025-accredited testing laboratories?

It meets fundamental accuracy and repeatability criteria for Class III instruments but lacks built-in audit trail, user authentication, or electronic signature capabilities required for full accreditation compliance.
What calibration standards are recommended for external calibration?

Class M2 or better stainless-steel weights per OIML R111, with nominal values matching ≥20% and 100% of maximum capacity (e.g., 6 kg and 30 kg weights).
Can the balance be used in environments with elevated humidity or dust?

The unit is rated IP42 (IEC 60529), offering limited protection against vertically falling water droplets and solid objects >1 mm—suitable for controlled indoor labs but not for unconditioned industrial floors.
Does the RS232 interface support bi-directional communication?

Yes—it accepts simple command strings (e.g., “S” for print, “T” for tare) and transmits real-time weight data with status codes in ASCII format.
Is firmware upgrade capability available?

Firmware updates are performed exclusively by authorized SUNNY HENGPING service centers using dedicated diagnostic tools; end-user modification is not supported.
