Precision Viscometer Cup — Key benefits and features Precision measurement you can rely on: Discharge orifice diameter 4 ± 0.02 mm and cup volume 100 ± 1 ml. Designed specifically for testing coatings with efflux times under 150 seconds and manufactured to meet GB/T 1723-93 for consistent, repeatable viscosity results. Reduces operator error and fatigue: The engineered seat structure holds the cup securely so the instrument can be operated without constant hand support. This minimizes user fatigue and reduces manual variation between tests. Easy, repeatable setup: A lift screw on the holder allows fine, tool-free height adjustment of the viscometer cup for consistent positioning. A built-in spirit level (bubble level) ensures the cup is perfectly level before each test. Complete timing control: A stopwatch is supplied for accurate timing of efflux measurements, enabling precise adherence to test procedures and standards. Durable, corrosion-resistant construction: Cup and fittings are made from pure brass with a stainless-steel discharge connector to resist rust and corrosion. The discharge valve uses a brass screw mechanism and a silicone seal at the bottom for leak-free operation and long service life. Practical specifications at a glance: Discharge hole diameter 4 ± 0.02 mm; cup volume 100 ± 1 ml; suitable for coatings with efflux time <150 s; compliant with GB/T 1723-93. How this product solves common problems Eliminates inconsistent results caused by poor leveling or hand-held testing through a stable holder and built-in level. Reduces downtime and maintenance from corrosion thanks to brass and stainless-steel materials. Simplifies setup for repeat tests via the adjustable lift screw and hands-free seat design, improving throughput in QC environments. Typical applications Paint and coatings quality control: Measure viscosity of solvent- and water-based coatings during production or before application to ensure consistent film formation and drying. Laboratory testing and R&D: Use for repeatable efflux measurements when developing formulations or comparing thinners and additives. On-site inspection and maintenance: Portable, robust construction makes it suitable for field checks on maintenance or repair jobs where quick viscosity verification is required.
