Overview
The JINGHAI SNB-1 rotational viscometer is a precision measuring instrument with a 16-bit microcomputer processor and a digital liquid crystal display (with blue backlight). It has a programmed design and is easy to operate. It can directly display viscosity, speed, torque percentage, rotor number and the maximum measurable viscosity under current conditions. Measurement performance and functionality are of professional level.
Features
Adopting a 16-bit microcomputer processor as the core of the stepper motor high-subdivision drive, the speed is stable and accurate.
2. Digital LCD screen with blue backlight, data display is clear and intuitive.
3. The buttons are clearly marked, programmed, and easy to operate.
4. Equipped with alarm function.
5. The screen directly displays the viscosity, rotational speed, percentile torque, rotor number and the maximum viscosity value that can be measured at the current rotational speed of the selected rotor.
6. The main control board and subdivision driver board are all made of patch technology, and the circuit design is based on a professional microcomputer processor, resulting in a reasonable and compact structure.
7. Measurement and correction of full scale and each gear Linearity are all carried out through the PC interface.
Principle
The Viscometer controls a stepper motor via a microcomputer processor that drives the rotor to swirl/spin in the fluid at a set constant speed. When the rotor swirls/spins in the fluid, it is subjected to Tack resistance, which generates torque. The instrument measures this torque value and calculates the viscosity value of the fluid according to the built-in program and calibrated parameters, and finally displays the result on the LCD screen.
Applications
Chemical, Petroleum, Food, Pharmaceutical, Coatings, inks, Adhesives, Cosmetics, Research and Education
Steps
1. Choose the appropriate rotor and speed according to the estimated viscosity value.
2. Install the selected rotor.
3. Immerse the rotor into the sample to be tested at the specified mark.
4. Turn on the power and set the required speed by pressing the button.
5. Start the measurement and read the viscosity value after the display value is stable.
6. After the measurement is completed, turn off the power and clean the rotor.
Notice
• Please ensure that the instrument is placed horizontally before use.
• When selecting the rotor and speed, the torque percentage reading should be in the range of 10% to 100% for the best accuracy.
• When immersing in the rotor, bubbles should be avoided and the specified immersion depth mark should be ensured.
The sample temperature should be kept constant during the measurement process to obtain accurate results.
• When the instrument is not in use for a long time, please disconnect the power supply.
• Use a suitable solvent when cleaning the rotor to avoid scratching or damaging the rotor surface.
• Please use the factory-specified Power Adapter.
