Product Overview

The HM-YN1 Kinematic Viscosity Tester is designed for determining the kinematic viscosity of liquid petroleum products (Newtonian liquids) in accordance with national and industry standard testing procedures. By measuring the gravity flow time of a fixed liquid volume through a calibrated glass capillary viscometer at a stable constant temperature, the instrument determines kinematic viscosity (mm²/s) and enables dynamic viscosity calculation when fluid density is known. Featuring a 7-inch industrial color touchscreen, German A-grade Pt100 temperature sensing, and an adjustable 60%–100% stirring system, the instrument ensures thermal uniformity across its ambient to +150°C operating span.

Related Models

For laboratories requiring integrated density measurement alongside viscosity, explore the HM-YN2 multifunctional analyzer. If sub-ambient testing down to 5°C is required without external cooling circulators, consider the compressor-equipped HM-WYN. For fully automated batch operations with auto-cleaning, refer to the HM-YN3 series.
