Kinematic Viscometer

Introduction

A kinematic viscometer measures fluid viscosity under gravity flow conditions. It is widely used in petroleum, chemical, and material testing laboratories. The system provides accurate viscosity data essential for process control and quality evaluation.

Standards

ISO 3219:1993-Plastics-Determination of viscosity using a rotational viscometer with defined shear rate

ASTM D445-24-Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids

ISO 3104:2023-Petroleum products-Transparent and opaque liquids-Determination of kinematic viscosity

GB/T 265-Petroleum products-Determination of kinematic viscosity and calculation of dynamic viscosity

ISO 23581:2024-Petroleum products-Determination of kinematic viscosity by Stabinger type viscometer

ASTM D2196-20-Standard Test Methods for Rheological Properties of Non-Newtonian Materials by Rotational Viscometer

Complies with the above standards, but is not limited to them.

Features

1. Wide viscosity range with interchangeable spindles covers many fluids.

2. Precise speed or shear settings suit different fluids.

3. Rotational or capillary method gives reliable viscosity values.

4. Temperature jacket or probe supports controlled measurements.

5. Automatic calculations and pass limits speed quality checks.

FAQ

What are the main applications of the Kinematic Viscometer?

The Kinematic Viscometer is used to measure the viscosity or flow behaviour of fluids. It supports formulation, batch consistency and quality control in paints, oils, food, pharmaceuticals, chemicals and cosmetics.

Which standards and regulations apply to the Kinematic Viscometer?

The instrument is designed with reference to applicable ISO, ASTM and GB/T standards for viscosity measurement and IEC 61010 electrical safety. Procedures should follow the relevant standard method. Compliance documentation can be provided on request.

How long is the warranty period?

A 12-month warranty applies to the complete equipment against defects in materials and workmanship. It excludes consumables, wearing components and accidental or misuse damage. Our service team handles claims against the serial number, and longer cover can be arranged.

Will staff need special training?

Day-to-day use is simple, with clear prompts and pre-set functions reducing manual steps. New operators should review the manual and complete a short familiarisation. Our technical team offers remote support during the first runs.

How long does delivery usually take?

Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

Does the Kinematic Viscometer need calibration or verification?

The unit is calibrated and tested before delivery. For ongoing accuracy, verify it against traceable reference standards every 6 to 12 months, or according to the laboratory quality schedule. We can arrange calibration service and certificates where required.

Are consumables and spare parts easy to obtain?

No proprietary consumable contract is required; standard parts are available from us and common laboratory suppliers. Our service team can supply a recommended parts list for the model. Most routine spares are held for quick delivery.

Are options or configurations available?

A range of options is available to match the application, such as alternative settings, fittings, data outputs or power supply. We confirm each option and its effect on price and schedule up front. Larger custom builds can be discussed.

Is installation and commissioning included?

Most models can be commissioned by following the manual, including positioning, connections, checks and a first test run. Remote guidance is available during start-up. On-site installation, commissioning and training can be arranged separately where required.

What should be avoided when using the Kinematic Viscometer?

Do not use samples outside the viscosity range, introduce bubbles or use damaged spindles. Control temperature, since viscosity is temperature dependent. Follow the operating instructions.
