MODERNER STM-VII Stormer Viscometer meets BYK standards
The STM-VII Stormer Viscometer meets the BYK standard. This Stormer Viscometer Measurement range is 40~141KU and uses an LCD screen. The STM-VII can display KU value, gm value and reference mPa.s value (or cP value) simultaneously.

STM-VII
The new STM-VII digital Stormer viscometer is suitable for determining the KU viscosity of coatings, paints and related products. The instrument is digitally displayed, no weights are required, and the LCD screen simultaneously displays the KU value, gm value and reference mPa.s value (or cP value), simplifying the test procedure.
Meets standards
ASTM D562 Standard Test Method: Determination of KU Viscosity of Coatings Using a Stormer Viscometer
GB/T 9269 "Determination of viscosity of coatings -- Stormer viscometer method"
Operating Principle
The principle is to immerse an offset paddle in a test sample and express the viscosity of the sample, i.e., the gm viscosity, by using the load value at 200 rpm (corresponding to the weight mass of a mechanical Stormer viscometer). The gm value is usually converted to the KU value (Krebs Unit) to express the viscosity of the sample.
The instrument has an RS-232 serial printing interface, which can print and display results online. The mPa.s value (or cP value) is converted from ASTM D562 standard and is for reference only. 1cP=1mPa.s. Considering the different habits of users at home and abroad, the instrument provides 1 500mL sample cup randomly. The STM-VII is available in English.
