Product Description
Model KV100 is a user-friendly capillary viscometer which operates excellent in rough process environments, on downgraded set-ups at pilot plants, as well as under semi-laboratory conditions.
The KV100 Capillary Viscometer easily measures low and medium viscosity materials. Based on the principle that the pressure decrease between the two ends of the measuring capillary is proportional to viscosity a permanent control signal is determined.
Features And Benefits
- Continuous measurement eliminates need for "Grab" sampling and allows for prediction and constant control of final product properties
- The gear pump forced internal sample flow via magnet coupling keeps the instrument resistant to pressure and temperature
- 4-20 mA output signal provides a variety of display and control capabilities
- Sample transport by aspiration tube into the viscometer creates bypass situation where measurement "Zone" is protected from main flow, allowing accurate, repeatable measurement under variable conditions
- Availability of various standard viscosity ranges up to 500 mPas (cP); customized ranges on request
- Display device for measuring data including calculation options

FAQs of KV100 Capillary Viscometer:
Q: How does the KV100 Capillary Viscometer ensure accurate viscosity measurements?
A: The KV100 uses a constant temperature bath regulated by a high-precision immersion heater and a digital temperature sensor, which maintains thermal stability to within 0.01C. This consistent environment, combined with a magnetic stirrer for uniform fluid temperature, minimizes measurement variability, ensuring reliable and reproducible results.
Q: What types of capillaries can be used with this viscometer?
A: This instrument is compatible with BS/IP/UBBLEOHDE, OSTWALD, REDWOOD, and CANNON-FENSKE capillaries. Such wide support allows users to select the appropriate tube based on their specific testing requirements and international standards.
Q: When is it ideal to use the KV100 Capillary Viscometer?
A: The KV100 is best suited for laboratory environments requiring precise kinematic viscosity measurements of both transparent and opaque liquids, particularly when conformity to ASTM D445 is crucial. Its robust design and precision make it suitable for routine quality control as well as advanced research.
Q: Where can this viscometer be employed?
A: Ideal for industrial, research, and QC laboratories, the KV100 can be found in petrochemical plants, universities, pharmaceutical companies, and other facilities in need of viscosity analysis. Its adherence to key standards makes it a trusted tool across various sectors.
Q: What is the sample handling process for viscosity determination?
A: To measure viscosity, a minimum sample volume of 20 ml is introduced into the compatible capillary. The bath temperature is set according to the testing method, and the digital timer initiates measurement as the sample flows through the capillary, enabling automated, precise timing and digital result display.
Q: How does the built-in memory backup benefit users during testing?
A: The digital timers memory backup ensures that measurement data and timing remain intact during power interruptions or accidental shutdowns. This safeguards test continuity and reduces the chance of data loss, contributing to greater operational efficiency.
