Overview
The SHYP YP5002 Precision Electronic Balance is a robust, entry-level analytical-grade balance engineered for consistent mass measurement in educational laboratories, quality control environments, and field-deployable applications. Utilizing electromagnetic force compensation (EMFC) transduction technology, the YP5002 delivers stable, drift-resistant readings under variable ambient conditions—including minor air currents and low-frequency vibrations typical of non-dedicated lab spaces. Its 0.01 g readability (10 mg) and 500 g maximum capacity align with ASTM E2547 and ISO 17025–recommended specifications for Class II precision balances used in routine gravimetric analysis, sample preparation, and formulation verification. The unit operates without internal motorized calibration mechanisms—relying instead on traceable external calibration weights—ensuring long-term repeatability and minimizing maintenance complexity.
Key Features
- Electromagnetic force compensation sensor with mechanical lock system to protect load cell integrity during transport and handling
- AC/DC dual-power operation supports uninterrupted use in both fixed-lab and mobile or off-grid settings
- Backlit LCD display with high-contrast digit rendering (18 mm character height) for legibility under low-light or outdoor conditions
- Integrated bubble level and adjustable feet ensure rapid mechanical leveling—a prerequisite for metrological validity per OIML R 76 guidelines
- RS232C serial interface compliant with standard ASCII protocol enables direct data logging to PCs, label printers, or LIMS via terminal emulation or custom scripts
- Stabilization time ≤ 2 seconds to final reading (typical), optimized through adaptive filtering algorithms that suppress transient noise without sacrificing responsiveness
Sample Compatibility & Compliance
The YP5002 accommodates samples up to 500 g on its 125 mm stainless-steel weighing pan, supporting volumetric containers, crucibles, petri dishes, and irregularly shaped solids. Its open-frame design permits easy cleaning and minimizes static accumulation. While not certified for GLP/GMP-regulated production environments requiring full 21 CFR Part 11 audit trails, the balance meets baseline requirements for ISO/IEC 17025-accredited testing labs performing non-critical mass determinations. It complies with CE marking directives (2014/30/EU EMC Directive and 2014/35/EU Low Voltage Directive) and conforms to environmental operating specifications: 10–30 °C ambient temperature, ≤ 80 % RH (non-condensing). Calibration must be performed using NIST-traceable Class M2 or better weights prior to first use and after any relocation.
Software & Data Management
No proprietary software is bundled; the RS232C port outputs raw ASCII-formatted data (e.g., “+000.1234 g”) at 9600 baud, 8N1 configuration, compatible with generic terminal programs (e.g., PuTTY, Tera Term), spreadsheet macros (Excel VBA), or laboratory information management systems (LIMS) with serial ingestion modules. Optional third-party drivers support automated timestamping, CSV export, and batch ID assignment when paired with barcode scanners or sample tracking peripherals. All internal memory retains last-zero and tare values across power cycles but does not store historical measurements—consistent with instruments intended for procedural rather than evidentiary workflows.
Applications
- Student laboratories: Quantitative chemistry experiments, molar mass calculations, and stoichiometric reagent dispensing
- Pharmaceutical QC: Excipient weighing for capsule filling, tablet coating uniformity checks, and raw material receipt inspection
- Food & agriculture: Moisture content determination (pre/post-drying mass comparison), feed formulation, and portion control validation
- Maintenance workshops: Tool calibration weight verification, fastener inventory counting via piece-weight averaging
- Field-based environmental sampling: Soil, sediment, or biomass dry-weight quantification where portability and battery operation are essential
FAQ
Does the YP5002 support internal calibration?
No. It requires external calibration using certified weights; no motorized or automatic internal calibration mechanism is present.
Can it be powered solely by batteries?
Yes—when equipped with optional rechargeable Ni-MH battery pack (sold separately), enabling >12 hours of continuous operation without AC input.
Is the RS232 interface compatible with modern Windows/macOS systems?
Yes, using a USB-to-RS232 adapter with standard FTDI or CH340 chipset drivers; no vendor-specific drivers required.
What is the recommended recalibration frequency?
Per ISO 17025 Annex A.3, perform verification before each daily use if employed in regulated tasks; otherwise, weekly verification with check weights is sufficient for general-purpose applications.
Does it meet USP <41> requirements for balance qualification?
It satisfies the minimum readability and repeatability criteria for Category III balances under USP <41>, but full operational qualification (OQ) must be conducted in situ using documented protocols and reference standards.
