## Description

Product Identity: This No. 4 stream-cup viscometer is a portable viscosity testing instrument designed for coatings, paints, and similar liquid materials, delivering reliable as needed consistency measurements.
Core Function: As a precision stream cup viscometer, it measures liquid viscosity by timing how long a fixed volume of fluid takes to stream through the bottom outlet nozzle, providing repeatable test results.
Construction Material: Built as a copper stream cup, it features a 100 ± 1 ml capacity, 49.5 ± 0.2 mm internal diameter, 4 ± 0.02 mm outlet nozzle, and 81° ± 15° internal cone angle for accurate testing performance.
Portable Design: This viscometer with carrying handle includes a looped metal carrying handle and a compact tapered body, supporting convenient transport, convenient handling, and simple storage between uses.
Application Purpose: As a practical viscosity tester, it supports consistent coating quality checks in workshops, laboratories, paint cooking areas, and at the job site field inspection environments.

This No. 4 stream-cup viscometer is a practical, portable viscosity testing instrument built for anyone working with coatings, paints, and similar liquid materials. Whether you are adjusting a paint batch in a workshop or running routine checks in a research facility, this tool gives you a straightforward way to assess liquid consistency on demand. As a precision stream cup viscometer, it operates on a simple and reliable principle: fill the cup with the test liquid, allow it to stream out through the bottom nozzle, and measure the elapsed time. This time-based measurement gives you a repeatable viscosity reading that you can use to compare batches, verify formulation consistency, or adjust dilution ratios before application. Built as a copper stream cup, it combines sturdy construction with meticulously machined dimensions to support accurate testing. It has a 100 ± 1 ml capacity, a 49.5 ± 0.2 mm internal diameter, a 4 ± 0.02 mm outlet nozzle, and an internal cone angle of 81° ± 15°, all of which contribute to consistent stream behavior test after test. The tapered cup body and bottom outlet are shaped to promote smooth, uniform draining. This viscometer with carrying handle is designed for real-world use further than workbench. Its looped metal carrying handle makes it easy to pick up, move between workstations, or hang on a storage hook when not in use. The small size factor also means it takes up minimal space on a workbench or inside a tool kit, so you can keep it close at hand wherever viscosity checks are needed. As a versatile viscosity tester, it fits effortlessly into a range of daily work scenarios. Paint technicians can use it to match batch consistency, coating applicators can verify material condition before a job, and lab can run rapid quality checks without complex equipment setup. With its portable size and straightforward, it brings reliable viscosity measurement to wherever your work takes place.

Option: Port Four Cup
