Density Meter and Moisture Meter Solutions for Laboratories and Production
These instruments quantify density and moisture across polymers, rubber, metals, powders, packaging, and paper. Built with in‑house R&D, CNC‑machined components, and traceable calibration, they deliver repeatable results aligned with common international methods. We provide clear interfaces, guided routines, and responsive after‑sales support.
Applications and Methods
- Plastics and rubber: material identification and batch control (ISO 1183, ISO 2781, ASTM D792).
- Metals and powders: bulk and tap density for packing and flow assessment; optional pycnometry.
- Packaging and paper: carton and paper moisture checks for converting and print readiness.
- Food, tobacco, biomass, grains: moisture content measurement with guided routines.
- Chemicals and adhesives: concentration by density; solids content via loss‑on‑drying (e.g., ISO 712 where applicable).
Measurement Principles
- Density: Archimedes buoyancy for solids (e.g., ISO 1183/ASTM D792), powder pycnometry, and liquid density by oscillation or buoyancy (ASTM D4052/ISO 12185).
- Moisture: halogen loss‑on‑drying with programmable heating profiles and oven‑reference workflows for method alignment.
Product Options
- Liquid densimeter: Thermostatic control supports formulation checks and concentration control. Guided calibration with certified standards helps ensure traceability.
- Solid densimeter: For plastics, rubber, and composites. Automatic temperature compensation and selectable immersion media; fixtures handle films, pellets, and irregular parts.
- Powder and bulk density tester: Interchangeable vessels for bulk/tap density. Analytics support correlation with flowability and packing behavior.
- Halogen moisture analyzer: Rapid loss‑on‑drying with standard/soft/step profiles. Real‑time mass and moisture curves with auto‑stop criteria help speed method setup.
- Paper/packaging moisture unit: Stabilized readings under ambient changes and pass/fail flags for line checks.
Core Features
- Precision hardware: CNC‑machined assemblies, anti‑drift load cells, and stable thermal design.
- Standards know‑how: Preloaded method templates mapped to common practices.
- Usability: Touchscreen UI, one‑key method recall, multilingual prompts, and audit trails.
- Data and connectivity: Statistics, trend charts, and export via USB/RS‑232/Ethernet.
- Reliability: ISO 9001 quality, in‑house calibration labs, and traceable verification kits.

Moisture analyzers:
- Range: 0.01%–100% moisture (material‑dependent).
- Readability: 0.001 g; moisture resolution to 0.001% (model‑dependent).
- Heating: halogen 40–200°C, up to 230°C on select models; programmable profiles with auto‑stop.
Customization, Compliance, and Support
Configure fixtures for films, wires, pellets, or irregular parts. Options include specialized sample pans, high‑temperature shields, and anti‑evaporation covers. Firmware can add custom methods, language packs, barcodes, and report templates. Calibration uses certified weights, density standards, and moisture verification materials. Method templates align with common practices, and our labs provide traceable certificates and maintenance plans.
How to Choose
- Define sample form and target range.
- Select the method: Archimedes, liquid density, bulk/tap density, pycnometry, or halogen loss‑on‑drying.
- Consider throughput, accuracy, temperature control, and data/reporting needs.
- Share your materials and limits; we will map the method to the right instrument and accessories.
FAQs
Q: What accuracy do I need?
A: Match instrument resolution to your spec limits and expected process variation.
Q: How do I validate methods?
A: Use certified standards and side‑by‑side checks with your reference method or oven.
Q: Can I test very small samples?
A: Yes. Micro fixtures and pans support small or delicate specimens.
Q: How should I handle volatile liquids?
A: Use temperature control, evaporation covers, and follow best‑practice prompts for stable readings.
