SOP TOP MP Series Heavy-Duty Electronic Balance

Overview

The SOP TOP MP Series Heavy-Duty Electronic Balance is an industrial-grade platform balance engineered for high-capacity, routine mass measurement in quality control laboratories, manufacturing floors, and warehouse logistics environments. Based on electromagnetic force compensation technology with reinforced load cell architecture, the MP Series delivers stable, reproducible results across its extended weighing range—from 60 kg up to 300 kg—with readability options of 1 g, 5 g, or 10 g depending on model configuration. Its robust mechanical design incorporates a large 400 × 500 mm stainless-steel weighing pan, integrated overload protection circuitry, and rapid stabilization (<2 seconds), enabling efficient throughput without compromising metrological integrity. The balance operates under ambient conditions typical of non-climate-controlled production areas (10–40 °C, ≤80% RH non-condensing), and is calibrated using standard external weights traceable to national metrology institutes—ensuring compliance with foundational requirements of ISO 9001, ISO/IEC 17025, and internal calibration SOPs.

Key Features

• Full-range tare and zero functions, supporting dynamic subtraction of container mass at any point within the maximum capacity
• Real-time overload detection with audible/visual alert and “OL” display indication; underload warning for low-mass instability
• Multi-function operation modes: counting (with sample size auto-calculation), percentage weighing, checkweighing, and density determination (when paired with optional density kit)
• Seven unit conversion options—including gram (g), kilogram (kg), pound (lb), ounce (oz), carat (ct), grain (gr), and Newton (N)—configured via front-panel keys
• Dual power operation: compatible with standard AC mains (100–240 V, 50/60 Hz) and optional rechargeable DC battery pack for portable deployment
• RS232 serial interface (standard on MP60K–MP200K; optional on MP300K) enables direct connection to PCs, PLCs, or LIMS for automated data capture
• Optional thermal printer support ensures compliant hard-copy record generation for audit trails and batch release documentation

Sample Compatibility & Compliance

The MP Series accommodates bulky, irregular, or palletized samples—ideal for raw material intake verification, finished goods packaging checks, and component weight sampling in automotive, pharmaceutical excipient, and food processing applications. Its wide pan surface and low-profile design minimize center-of-gravity errors during off-center loading. While not certified for legal-for-trade use (e.g., NTEP or EC Type Approval), the balance meets functional performance criteria referenced in ASTM E1223 (Standard Guide for Estimating Number of Samples), USP (Balances), and ISO 17025 Clause 6.4.3 (Equipment Verification). All models undergo factory verification per SOP TOP’s internal metrological protocol, including repeatability, linearity, eccentricity, and sensitivity tests—documentation available upon request for laboratory accreditation audits.

Software & Data Management

Data output via RS232 follows ASCII-based transmission protocol (9600 baud, 8N1), compatible with common laboratory software including LabWare LIMS, Thermo Fisher SampleManager, and custom Excel VBA macros. Each transmitted record includes timestamp (if enabled via external clock sync), gross/net/tare values, unit identifier, and status flags (e.g., “ST” for stable, “UN” for unstable). Optional SOP TOP BalanceLink™ PC utility (Windows 10/11) provides real-time graphing, statistical summary (mean, SD, CV%), and CSV/PDF report export—supporting 21 CFR Part 11–aligned user access controls when deployed on domain-managed systems. Audit trail functionality records all calibration events, parameter changes, and firmware updates with operator ID and timestamp.

Applications

• Raw material receipt inspection in chemical and pharmaceutical manufacturing
• Batch weight verification prior to sterilization or lyophilization
• Component counting for electronic assembly lines (e.g., PCBs, connectors, fasteners)
• Packaging line checkweighing to ensure net content compliance with labeling regulations (e.g., EU Directive 76/211/EEC)
• Warehouse inventory reconciliation and pallet load verification
• Educational labs requiring durable, multi-user weighing platforms for physical science curricula

FAQ

Is the MP Series suitable for regulatory submissions under FDA or EMA guidelines?
It supports data integrity practices required by FDA 21 CFR Part 11 when used with validated software and controlled access protocols—but is not itself a regulated device. Final compliance depends on site-specific validation (IQ/OQ/PQ) and SOP implementation.
What calibration weights are required for MP150K?
A 100 kg Class M2 or better external weight is recommended for full-span verification; intermediate points (e.g., 50 kg, 100 kg) should be checked per ISO 17025 calibration interval schedules.
Can the balance be mounted on a vibration-isolation table?
Yes—its internal damping system is optimized for moderate environmental vibration, but for high-precision applications near machinery or HVAC units, passive isolation tables meeting ISO 5347 standards are advised.
Does it support automatic internal calibration?
No—calibration is external only; no motorized weight mechanism or temperature-compensated internal reference is included.
What is the warranty coverage?
Standard 24-month limited warranty covering parts and labor for defects in materials and workmanship under normal use; extended service plans available through authorized SOP TOP distributors.
