Boehm viscosity tester

Product introduction:

        The DND-3s Boehmite Viscometer is an upgraded and improved product based on the original DND-3 Boehmite viscosity tester. The DND-3s increases the temperature and temperature of the test tube from the two aspects of the accuracy and convenience of the measurement. Accurate calibration of a 1/3B precision mobile electronic package in 316 stainless steel. Standard temperature sensor (replaces a glass mercury thermometer that requires manual visual inspection and is fragile). DND-3s uses industrial grade high resolution color touch screen, 32bit 400MHz MCU, provides two-way monitoring of bath temperature and temperature of the tested product, provides interactive temperature calibration and calibration, provides correction and calibration of interactive viscosity tube correction factor, and provides any Temperature setting and constant environment. It also has a print function option.
