NDJ-1D Digital Brookfield Rotational Viscometer, Brookfield Rotary Viscosimeter

Specifications

I. Summary
 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.
