The AVAIN LABS® Digital Automatic Viscometer (AL-22B) provides high-precision fluid viscosity measurements tailored for quality control, industrial processing, and research laboratories. Featuring a bright, large backlit LCD display and an intelligent auto-scanning function, the AL-22B automatically scans and recommends the optimal combination of rotor speed and spindle for your sample. With an extended measuring range from 20 to 2,000,000 mPa.s and ultra-fine resolution accurate to two decimal places (0.01 mPa.s), this digital rotational viscometer delivers precise, repeatable results for adhesives, cosmetics, paints, food products, and chemical formulations.
