METTLER TOLEDO HS153 Halogen Moisture Analyzer

Overview

The METTLER TOLEDO HS153 Halogen Moisture Analyzer is a precision laboratory instrument engineered for rapid, reproducible determination of moisture content in solid and semi-solid samples using thermogravimetric principle. It employs a high-intensity halogen lamp as the heating source, delivering uniform, controllable thermal energy to accelerate sample drying while minimizing thermal degradation risks. The analyzer integrates a high-resolution analytical balance (0.001 g readability) with an optimized heating chamber and advanced thermal management to ensure consistent heat transfer across diverse matrix types—including powders, granules, pastes, and hygroscopic materials. Designed for compliance-driven environments, the HS153 supports traceable, auditable workflows aligned with GLP and GMP requirements, making it suitable for QC laboratories in pharmaceuticals, food manufacturing, chemicals, and materials science.

Key Features

• Halogen heating technology: Provides fast, stable, and homogeneous heating (40–230 °C, 1 °C increments), enabling precise method optimization for thermally sensitive or heterogeneous samples.
• High-precision weighing system: Achieves 0.01 % moisture content readability and repeatability of ±0.01 % (std. dev.) for 10 g samples—critical for low-moisture applications such as polymers or dried pharmaceutical actives.
• Three preconfigured drying programs: Slow, Standard, and Fast modes allow adaptation to sample volatility, particle size, and surface area without manual parameter tuning.
• Intelligent auto-end detection: Supports five standardized Stop-On-Change (SOC) criteria plus fully customizable endpoints based on absolute mass loss (1–10 mg), time duration (5–300 s), or relative moisture loss (%).
• Touchscreen interface with embedded guidance: Includes method development wizard, temperature assistant, real-time drying curve visualization, control charts, and context-sensitive user prompts to reduce operator dependency and training time.
• Hygienic and serviceable design: Suspended weighing pan and flat stainless-steel chamber base facilitate rapid cleaning and residue removal—essential for cross-sample integrity in regulated labs.

Sample Compatibility & Compliance

The HS153 accommodates samples up to 150 g and delivers reliable results across a broad range of industrial matrices: foodstuffs (e.g., flour, dairy powders, snacks), chemical intermediates (e.g., catalysts, salts, resins), pharmaceutical excipients and APIs, and construction materials (e.g., cement additives, clays). Its measurement principle conforms to ASTM D4442 (wood moisture), ISO 712 (cereals), and USP <921> (moisture determination). All stored methods and results include timestamps, user IDs, instrument serial numbers, and audit trails—enabling full compliance with FDA 21 CFR Part 11 when paired with METTLER TOLEDO LabX software. Password-protected multi-user access (up to 10 profiles), automatic session timeout, and electronic signature support further reinforce data integrity in regulated settings.

Software & Data Management

Data export and integration are streamlined via multiple communication interfaces: USB host port (for direct export to flash drives), RS232 (legacy printer or PLC connectivity), Ethernet/Wi-Fi (for networked LabX deployment or FTP server upload), and optional Wi-Fi-enabled remote monitoring. Up to 3,000 test results and 100 user-defined methods can be stored onboard. Export formats include CSV, PDF, and XML—compatible with LIMS and ERP systems. When connected to LabX, the HS153 supports centralized method distribution, automated report generation (A4/letter format), scheduled calibration reminders, electronic batch records, and full 21 CFR Part 11-compliant audit trail logging—including all parameter changes, result edits, and user logins.

Applications

• Quality control of incoming raw materials (e.g., starch, lactose, silica) per pharmacopeial specifications
• Batch release testing of lyophilized biologics and tablet granulations
• Moisture stability studies under ICH Q1A conditions
• Routine analysis of food products for shelf-life prediction and labeling compliance (e.g., EU Regulation 1169/2011)
• Process optimization in spray-drying, fluid-bed granulation, and hot-melt extrusion
• Research into hygroscopicity and water activity relationships in polymer blends and composites

FAQ

What standards does the HS153 comply with for moisture analysis?
The HS153 supports methodologies referenced in ASTM D4442, ISO 712, ISO 15512, USP <921>, and Ph. Eur. 2.2.32—providing documented equivalence to classical oven-drying where validated.
Can the HS153 be integrated into a networked laboratory environment?
Yes—it features native Ethernet and Wi-Fi connectivity, enabling seamless integration with LabX software for centralized data management, remote monitoring, and electronic record archiving compliant with 21 CFR Part 11.
Is calibration traceable to national standards?
All internal weight and temperature calibrations are traceable to NIST (USA), PTB (Germany), or other national metrology institutes via METTLER TOLEDO’s certified calibration services and SmartCal verification tools.
How does the HS153 handle samples prone to splattering or surface hardening?
The adjustable drying profile—including ramp rates, hold times, and dual-stage temperature programming—minimizes crust formation. Optional glass fiber filters and sample spreading tools are available to improve drying homogeneity.
What security features support multi-user regulatory compliance?
Role-based access control, password complexity enforcement, automatic session lockout, electronic signatures, and immutable audit logs meet ALCOA+ principles and are fully enabled under LabX configuration.
