Overview

This integrated instrumentation suite comprises nine distinct, application-specific analytical and physical testing devices engineered for laboratory, quality control, and industrial R&D environments. The HAD-H370 is a certified intrinsically safe capacitive humidity and dew point analyzer designed for hazardous area deployment (Exd IIC T6), measuring relative humidity (0–100% RH), volumetric absolute humidity (0–40% vol), and dew point temperature (−20 to +100 °C) with ≤±1.5% FS accuracy. The HAD-HT625B digital vane anemometer delivers simultaneous wind velocity (0.40–30.00 m/s), ambient temperature (−20.0 to +60.0 °C), and dew point (−50.0 to +60.0 °C) readings via a calibrated axial impeller sensor. The HAD-100C horizontal roll press enables controlled cold rolling of battery electrode coatings and metallic foils using dual hardened 9Cr2Mo steel rollers (Φ100 mm, HRC62, cylindrical tolerance ±0.002 mm) with adjustable gap (0–3 mm) and variable line speed (0–6.0 m/min). The FERROMASTER portable permeameter quantifies low magnetic permeability (μ = 1.001–1.999) in austenitic stainless steels, NMR components, and non-ferrous alloys using dual-field Hall-effect sensing referenced to UK National Physical Laboratory (NPL) traceable standards. The HAD-W200A automatic tensiometer implements the Du Noüy ring method per ASTM D971, ISO 6295, GB/T 6541, and QB/T 1323, delivering surface/interfacial tension measurements (0–200.0 mN/m) with ≤±1% FS repeatability. The HAD-KM-5A particle abrasion tester complies with HG/T 2158–2004 and GB/T 36365–2018 for catalyst and adsorbent attrition evaluation under programmable rotational conditions (25–60 rpm, 0–99 min). The HAD-CRACK-8 smart crack width gauge performs non-contact optical measurement of structural concrete and metal surface cracks (0.01–8.00 mm) with automated edge detection, USB data export, and BMP/JPEG image capture. The 316L stainless steel LPG sampling cylinder (5000 mL, 4 MPa W.P.) conforms to ISO 4745 and ASTM D1265 for representative liquefied petroleum gas sampling. The SH0387 wire rope grease slippage tester executes standardized thermal migration assessment per SH 0387 at temperatures up to 200 °C (±0.5 °C control). Finally, the cross-flow cooling fan meets JB/T 8971–1999 for dry-type transformer derating applications, featuring aluminum die-cast impellers, low-noise ball bearings, and silicon steel laminations.

Sample Compatibility & Compliance

All instruments are validated for use with materials commonly encountered in energy storage, petrochemical, metallurgical, civil infrastructure, and pharmaceutical manufacturing sectors. The HAD-H370 complies with IEC 60079-0/-1/-11 for explosive atmospheres and meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU). The HAD-W200A supports GLP-compliant data integrity through timestamped result logging and operator ID fields (when integrated with optional PC software). The FERROMASTER adheres to ISO/IEC 17025 metrological traceability protocols via its NPL-certified calibration reference. The HAD-KM-5A satisfies Chinese national standards for catalyst attrition (HG/T 2158) and aligns with ASTM D5756 for solid particulate erosion testing. The HAD-CRACK-8 generates audit-ready reports conforming to GB 50292–2015 (Code for Safety Assessment of Existing Buildings) and EN 1504-4 for structural condition monitoring. None of the listed instruments require FDA 21 CFR Part 11 validation, though raw data files (BMP, CSV, TXT) are natively exportable without proprietary encryption.

Software & Data Management

FAQ

Is the HAD-H370 certified for Zone 1 hazardous locations?
Yes—the entire assembly carries Exd IIC T6 certification per IEC 60079-1, permitting installation in gas Group IIC environments with maximum surface temperature ≤85 °C.
Can the FERROMASTER measure permeability below μ = 1.001?
No—its lower detection limit is fixed at μ = 1.001. For diamagnetic materials (e.g., copper, water), alternative techniques such as SQUID magnetometry are required.
Does the HAD-W200A support platinum-iridium rings per ISO 14070?
Yes—ring accessories conforming to ISO 14070:2021 Annex A are available as optional add-ons; standard configuration uses ASTM E1138-compliant stainless steel rings.
What is the maximum particle size acceptable for the HAD-KM-5A abrasion test?
Particles must pass through a 4.75 mm sieve prior to loading; oversized fragments may damage drum baffles or induce non-uniform wear patterns.
Are calibration certificates supplied with each instrument?
Factory calibration certificates (including uncertainty budgets) are included for HAD-H370, FERROMASTER, and HAD-W200A. Traceable recalibration services are offered annually with NIST-traceable reference standards.
