SUNNY HENGPING ESH Series Halogen Moisture Analyzer with Full-Touch TFT Interface

Overview

The SUNNY HENGPING ESH Series Halogen Moisture Analyzer is a precision benchtop instrument engineered for rapid, reliable, and traceable moisture content determination in solid and semi-solid samples via loss-on-drying (LOD) methodology. Utilizing a high-stability 600 W quartz halogen heating element, the system delivers uniform thermal energy distribution across the sample surface—minimizing thermal gradients and ensuring reproducible drying kinetics. Unlike conventional infrared systems relying on broad-spectrum emission, the ESH series employs focused halogen radiation optimized for efficient water evaporation without carbonization or decomposition of thermally sensitive matrices. Its integrated electromagnetic force restoration weighing sensor—available in three sensitivity tiers (5 mg, 1 mg, and 0.1 mg)—provides real-time mass tracking with high linearity and temperature compensation, meeting the metrological requirements for QC laboratories operating under ISO/IEC 17025 and GMP environments.

Key Features

• Full-touch 4.3″ TFT interface with intuitive step-by-step workflow guidance—no external PC required for operation or method setup
• Integrated electronic level indicator ensures consistent horizontal alignment prior to measurement, critical for gravimetric accuracy
• Patented heat-concentrating ring design enhances thermal efficiency while maintaining safe outer casing temperatures during extended operation
• Automatic lid-drop prevention mechanism and lid-open power cutoff comply with IEC 61010-1 safety standards for laboratory equipment
• Removable sample pan support plate and modular halogen lamp assembly simplify cleaning, calibration verification, and maintenance
• Natural convection air channel architecture eliminates forced-air turbulence that may disturb fine particulates or cause sample displacement
• Dedicated anti-tangle power cord with reinforced strain relief minimizes accidental disconnection during routine use
• Optically clear panoramic viewing window enables real-time visual monitoring of drying behavior without interrupting the measurement cycle
• Intelligent weight-based sample loading validation prevents erroneous results caused by over- or under-filling

Sample Compatibility & Compliance

The ESH analyzer accommodates a wide range of industrial and pharmaceutical materials—including powders, granules, pellets, pastes, and thin films—with nominal pan diameter of 100 mm. Its adjustable temperature range (40–180 °C) and multi-mode heating profiles (Standard, Progressive, Step) allow method optimization for hygroscopic, volatile, or heat-labile substances. The instrument supports compliance-driven workflows: built-in audit trail functionality logs operator ID, timestamp, method parameters, and raw mass data per test; all stored records are non-editable and time-stamped—satisfying FDA 21 CFR Part 11 requirements when paired with appropriate access controls. It conforms to ASTM D4442 (moisture in wood), ISO 712 (cereals), USP , and EP 2.2.32 methodologies for LOD-based moisture quantification.

Software & Data Management

No proprietary software installation is required—the embedded operating system handles all data acquisition, calculation, and reporting locally. Each measurement yields four concurrent outputs: moisture % (w/w), moisture mass (g), dry residue % (w/w), dry residue mass (g), and wet/dry ratio. All values are computed using ISO-defined LOD equations and automatically corrected for tare weight drift. Up to 36 complete test histories—including initial mass, final mass, temperature profile, duration, and calculated moisture content—are retained onboard with date/time stamping. Export is supported via USB port to CSV format for integration into LIMS or statistical process control (SPC) platforms. Calibration routines include internal weight verification and external span adjustment, both logged with user ID and timestamp.

Applications

• Pharmaceutical manufacturing: raw material release testing, excipient moisture specification verification, and stability study support per ICH Q1 guidelines
• Food & beverage QA/QC: moisture control in flour, sugar, dairy powders, coffee beans, and snack products to ensure shelf-life and microbial safety
• Chemical industry: solvent residue analysis in catalysts, polymer pellets, and specialty salts
• Agricultural testing labs: grain moisture assessment aligned with national standard GB/T 5497
• Plastics & composites: pre-drying validation for injection molding feedstock to prevent hydrolysis defects
• Research institutions: method development for novel biomaterials where thermal degradation thresholds must be empirically determined

FAQ

Does the ESH series support GLP-compliant documentation?
Yes—each test record includes immutable metadata (operator ID, date/time, method name, temperature setpoint, duration, and raw mass readings), fulfilling core GLP data integrity requirements.
Can the halogen lamp be replaced by the user?
Yes—the lamp module is tool-free and field-replaceable, with no recalibration needed post-installation.
Is external calibration weight included?
No—calibration weights must be sourced separately per ISO 9001 or ISO/IEC 17025 traceability requirements.
What is the expected lifetime of the halogen heating element?
Rated for ≥10,000 hours of continuous operation under normal laboratory conditions (per IEC 60335-2-9).
How does the instrument handle samples prone to splattering or foaming?
The progressive and step heating modes allow gradual ramping to minimize surface disruption; optional glass fiber filters or perforated aluminum pans can be used to contain volatile components.
