Overview
The SHYP YP30002 Precision Electronic Balance is a high-stability, entry-level analytical-grade weighing instrument engineered for routine laboratory, educational, and light industrial applications where reproducible mass measurement in the 0–3000 g range is required. Based on electromagnetic force compensation (EMFC) transduction technology, the YP30002 delivers consistent 0.01 g readability across its full capacity, ensuring reliable data acquisition under variable environmental conditions. Its compact footprint (250 × 180 × 60 mm), integrated leveling bubble, and robust mechanical design—featuring a patented sensor locking mechanism for transit protection—make it suitable for both fixed benchtop use and mobile field deployment. The balance operates seamlessly on either AC mains power or DC battery supply, eliminating dependency on stable electrical infrastructure—a critical advantage in teaching labs, quality control stations, and remote calibration environments.
Key Features
- Electromagnetic force compensation (EMFC) load cell with internal damping for rapid stabilization (<2 seconds typical settling time at full load)
- External calibration capability using standard Class M2 or better weights; multi-point calibration option supports traceable verification workflows
- Backlit LCD display with 18-mm character height for clear visibility under low ambient light or glare-prone conditions
- Dual-power architecture: auto-switching between AC adapter (included) and rechargeable DC source (optional)
- Integrated leveling bubble and adjustable feet for precise horizontal alignment—essential for metrological integrity
- RS232C serial interface compliant with EIA/TIA-232-F standards, enabling direct connection to PCs, label printers, or LIMS terminals without additional converters
- Shock-absorbing pan mount and reinforced stainless-steel weighing pan (Φ125 mm) resistant to corrosion and mechanical wear
Sample Compatibility & Compliance
The YP30002 accommodates a broad range of sample types—including powders, granules, liquids in containers, and small solid objects—within its 3000 g capacity and 125 mm diameter pan. Its sealed housing meets IP42 ingress protection specifications, offering resistance to dust accumulation and incidental splashes during routine handling. While not certified to ISO/IEC 17025 or OIML R76 as a legal-for-trade instrument, the YP30002 adheres to fundamental metrological principles aligned with ISO 9001-supported quality control processes. It supports GLP-compliant documentation when paired with validated RS232 data logging software, and its external calibration protocol enables alignment with national metrology institute (NMI)-traceable standards via user-supplied reference masses.
Software & Data Management
Data output follows ASCII-based serial framing (9600 baud, 8N1), compatible with standard terminal emulators and spreadsheet import tools. Optional SHYP DataLink software (v3.2+) provides timestamped batch export, statistical summary (mean, SD, CV%), and CSV/Excel-compatible reports—supporting audit-ready records for internal QC audits. The RS232 interface supports command-driven operation (e.g., “S” for stable weight readout, “Z” for zero, “T” for tare), facilitating integration into automated test sequences. No proprietary drivers are required; native OS serial port support suffices for Windows, macOS, and Linux platforms.
Applications
- Educational laboratories: stoichiometric preparation, density determination, and gravimetric analysis instruction
- Pharmaceutical QA/QC: raw material receipt inspection, tablet weight uniformity checks per USP , and excipient dispensing
- Food & agriculture: moisture content sampling, feed formulation, and portion control validation
- Materials testing labs: powder blending homogeneity assessment and additive dosing verification
- Maintenance workshops: tool inventory reconciliation and component weight logging
FAQ
What is the recommended calibration frequency for the YP30002 in a controlled lab environment?
Calibration should be performed before first use, after relocation, following significant temperature shifts (>5°C), and at least once per shift when used in regulated settings. Daily verification with a check weight is advised.
Does the YP30002 support internal calibration or require external weights?
It supports external calibration only. A 2000 g Class M2 calibration weight is recommended for full-span verification.
Can the balance store multiple tare values or user profiles?
No. It retains only the most recent tare value and does not support user memory banks or profile storage.
Is the RS232 interface optically isolated?
No. The interface is electrically coupled; use of a grounded USB-to-serial adapter with surge suppression is recommended in electrically noisy facilities.
What environmental conditions affect measurement stability?
Air currents, vibration, static charge, and thermal gradients exceeding 1°C/hour may impact repeatability. Use on a granite or vibration-dampened bench is strongly advised.
