Key Features & Benefits
•ISO 2431 / DIN / EN / ISO compliant — ensures standardized viscosity measurement, supporting quality control protocols and regulatory compliance.
•Multiple nozzle/orifice options (Ø 3, 4, 5, 6, 8 mm) — enables flexible measurement across a wide range of viscosities, from thin solvent‑borne coatings to heavier high‑solids or high‑viscosity coatings.
•Durable construction — anodised aluminium body with stainless‑steel nozzle guarantees longevity and resistance to wear, solvents or cleaning procedures.
•Traceability & calibration readiness — every cup can be supplied with a factory calibration certificate on demand, supporting documentation and traceable quality control.
•Simple, quick test method — fast flow‑time measurement with stopwatch, allowing efficient QC testing on multiple batches or production lots.
•Compatible with standard cup stands & supports — ensures stable and reproducible test setups in labs or production environments.
•Cost‑effective viscosity control — provides an economical yet reliable tool for routine QC, formulation checks and batch-to-batch consistency verification.
