DV-79 Digital viscometerDetailed product description：

The DV-79 digital viscometer is an improved version of the original NDJ-79 mechanical viscometer.
The DV-79 digital viscometer is a significant improvement based on the original NDJ-79 mechanical viscometer. It adopts a 16 bit microcomputer processor as the core of a stepper motor high subdivision drive and a digital LCD with blue backlight function for a digital viscosity measuring instrument. The speed is stable, the measurement is accurate, and the operation is simple. When the torque is below 20% and above 90% of the measurement range, the instrument will issue an alarm. The RTD temperature probe can monitor and measure the temperature of the sample in real time, with an accuracy of 0.1 ℃. The temperature measurement range is -20 ℃ -120 ℃. The screen directly displays viscosity, speed, temperature, percentage torque, rotor number, and the maximum measurable viscosity value of the selected rotor at the current speed.

Product certification: CMC metrology production license number Hu Zhi 00000 67 and ISO9001:2000 international quality management system certification.
