DV-H series digital high temp. viscometer adopts 16-bit micro processor control circuit and high-subdivison stepping motor to make its measuring range wider. It is mainly used in the measurement of those substances which is solid under room temperature while becomes liquid when heated, such as hot melt glue/asphalt or rosin resin, petroleum resin, polyethylene wax etc.
- It can be used independently, all the data will be display on the screen directly without further calculation; meanwhile optional “data acquisition analysis and graphing software” is available for analysis and monitoring viscosity-temperature curve.
- Adopt high-subdivision stepping motor with precision and stable speed.
- LCD display with blue black light, directly display viscosity, rotor speed, percentage torque, rotor no, RTD temperature and the maximum viscosity can be measured under present speed using rotor selected. DV-2H series can also display shear rate, shear stress. Viscosity changes continuously, there will be alarm if over measurement range.
- The measuring performance after computer correction, accuracy reaches the same level of foreign products.
- Heating furnace adopts built-in integral heating with uniform heating and low heat inertia.
