Overview
The NDJ-8S + LC-1008 is a digital Rotational Viscometer and Thermostatic bath system. The Viscometer LCD screen displays viscosity, Rotation speed, temperature, percentile torque, rotor number and the maximum measurable viscosity of the selected rotor at the current Rotation speed, with a range of 20 to 2,000,000 mPa · s. The Thermostatic bath LC-1008 has heating and cooling functions. Temperature range is -10 ° C to 100 ° C, which can realize automatic heating, thermostatic and cooling control of the sample during the test.

12. Multiple operation modes are optional, and accidental power failure can be automatically restored.
13. Optional intelligent control function, supports multiple interfaces (RS485, RS232) for remote communication, or starts and stops controlled by external devices through 0-10V/4-20mA analog signals.
Principle
The product uses a Rotational Viscometer to measure fluid viscosity. The motor drives the rotor to swirl/spin in the fluid. The torque generated by the fluid Tack resistance twists the Sensor of the motor, and the viscosity of the fluid is calculated by measuring this torque value. The matching Thermostatic bath uses the intelligent PID temperature control system to perform precise temperature control on the sample, ensuring that the viscosity measurement is carried out under constant temperature conditions and improving the measurement accuracy.
Applications
Petrochemicals, Paint inks, Food and Medicine, Cosmetics, Adhesives, Research and Education
Steps
Connect the Viscometer host to the Thermostatic bath LC-1008 correctly and power it on.
2. Choose the appropriate rotor and Rotation speed according to the estimated viscosity range of the sample to be tested.
3. Set the Thermostatic bath to the desired test temperature and start the thermostatic program.
4. After the temperature of the Thermostatic bath stabilizes, place the measurement cup containing the sample into the Thermostatic bath or connect the external circulation jacket.
5. Install the selected rotor on the Viscometer and carefully lower into the sample to the specified scale line.
6. Set the corresponding rotor number and Rotation speed on the Viscometer to start the measurement.
7. After the reading is stable, record the viscosity value and Miscellaneous parameters displayed on the LCD screen.
8. After the measurement is complete, lift the rotor and clean it.
Notice
Please read the instructions carefully before use.
• Power supply voltage compliance (Viscometer uses a dedicated Power Adapter, Thermostatic bath 200~ 230V AC).
• Thermostatic bath Ambient Temperature should be 5~ 32 ℃, relative humidity ≤ 80%.
• When the Thermostatic bath is running, please ensure that the liquid level is sufficient to avoid low liquid level alarm or dry burning.
• Be careful when installing and removing the rotor to avoid bending or damaging the shaft.
• When measuring different samples, thoroughly clean the rotor and measurement cup to prevent cross-contamination.
Do not use it beyond the range of the instrument or under permissible conditions.
The instrument should be placed on a stable surface to avoid vibration.
• When not in use for a long time, please disconnect the power supply and store the instrument in a drying place after cleaning.
