Koehler – Viscometer – Kinematic Viscosity Bath
KV5000 model Kinematic Viscosity Baths with optical flow detection system provide automatic viscosity measurements of petroleum and petrochemical products. Includes communication and power ports for each optical detection assembly, and can utilize up to five optical assemblies. Two additional positions are available for manual viscosity measurements, and all positions can be used in the manual mode. The interchangeable Ubbelohde, Cannon®- Fenske, and Cannon®- Fenske Opaque Reverse Flow viscometer tubes are quickly installed and removed from the detection assemblies for cleaning and simple tube changes. Allows for automatic viscosity measurements and results calculation without an external PC. Motorized stirrer provides complete circulation without turbulence. Microprocessor PID circuitry assures precise, reliable temperature control within ASTM specified tolerances throughout the operating range. Simple push-button controls and dual digital displays permit easy setting and monitoring of temperature. Two place calibration offset capability is provided. Built-in cooling coil facilitates temperature control at ambient or below ambient temperatures.
- Complete instrument and data acquisition system exclusively designed for conducting ASTM D445, IP 71 and related test methods
- Optical sensor detection system accurately measures sample flow and automatically calculates kinematic viscosity results
- Powerful software system for PC platforms operating in Windows® XP, Vista, 7 and 8 environments
- Automatic calculation and display of results in viscosity units or seconds
- Accommodates Ubbelohde, Cannon®- Fenske, and Cannon®- Fenske Opaque Reverse Flow viscometers
- High accuracy temperature control with dual digital displays show set point and actual bath temperature with selectable scale (°C or °F)
- Stand alone feature provides for automated testing without an external PC
- Integrated redundant over-temperature and low liquid level cut-off circuitry
- Software exports test data with graphs and test parameters direct to CSV file format for use with LIMS or any other spreadsheet program
- Integrated digital timing for easy measurement of sample efflux times
