KV4000 Kinematic Viscosity Bath with Integrated Digital Timing, Koehler Instrument Company
or call us at 1-800-727-0467
Constant temperature bath with advanced temperature control circuitry and integrated timing features for convenient, accurate glass capillary viscometry determinations. Microprocessor PID circuitry assures precise, reliable temperature control within ASTM specified tolerances throughout the operating range of the bath. Simple push-button controls and dual digital displays permit easy setting and monitoring of bath temperature. Two place calibration offset capability is provided. The bath accommodates seven glass capillary viscometers of various types. Viewing the viscometers is made easy by glare-free LED illumination inside the bath and a baffle that provides a background for easy viewing. Temperature control uniformity is assured by means of motorized stirrer which provides complete circulation without turbulence. Connection of the built-in cooling coil to tap water or a recirculating water chiller facilitates temperature control at ambient or below-ambient temperatures. Communications software (RS232, etc.) ramp-to-set and other enhanced features are available at an additional cost.
Integrated Timing Features -The user can enter the viscosity constant for each viscometer on the front Touch Screen Control Panel and then get the test result in both efflux time and viscosity units automatically after stopping each timer. Timing function is displayed in 0.01 second resolution and is accurate within 0.01%.
Test Method:
Kinematic viscosity is of primary importance in the design and selection of a wide range of petroleum products. Calibrated capillary viscometers are used to measure flow under gravity or vacuum at precisely controlled temperatures.
