NDJ-1D Brookfield Rotational Viscometer

Summary

  The instrument is designed and made as per T0625 "Asphalt Brookfield Rotational Viscosity Test (Brookfield Viscometer Methods)" in the Industry standard of People's Republic of China JTJ052 Specifications and Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering. It is the upgrade one of NDJ-1B and NDJ-1C Rotational Viscometers. It is suitable to determine the absolute viscosity of Newtonian liquids and the apparent viscosity of Non-Newtonian liquids.

  It adopts advanced mechanical design and manufacturing techniques, and uses a microprocessor for temperature control, data collection and data process.The LCD is a white backlight, ultra-bright LCD. It is also equipped with a micro-printer. Test dada can be shown on the LCD and/or printed out from a printer.The instrument has a RS232 communication port to connect with a computer.

  It is sensitive, reliable, generous and easy to be operated. It is widely used for determining viscosities of asphalt, hot melt adhesive, paraffin, high polymer, and other liquids.
