Product Description
Koehler HKV3000 High Temperature Kinematic Viscosity Bath with Integrated Digital Timing features for convenient, accurate glass capillary viscometry determinations.
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. 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. Baths accommodate seven glass capillary viscometers of various types. Viewing the viscometers is made easy by glare-free fluorescent 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 additional cost.

Integrated Timing Features _ HKV3000 incorporates seven digital timers on the front control panel for convenient timing and monitoring of the efflux interval for each viscometer. All timing functions are displayed in 0.01 second resolution and are accurate within 0.01%.

Bath Construction and Safety Features _ Bath chamber is a clear Pyrex vessel enclosed in a polyester-epoxy finished steel housing. Top working surface has seven 2" (51mm) viscometer ports and is constructed of stainless steel for easy cleaning. Front viewing window assures safe, distortion-free viewing. Microprocessor temperature controller incorporates safety circuitry that interrupts power to the heaters in the event of an over-temperature condition or disconnection of the primary probe. For added safety, a redundant adjustable controller with separate sensor probe interrupts power if an over-temperature situation occurs. An integrated low-liquid sensor prevents operation of the bath if the bath liquid is not filled to the proper level, and cuts off power should it fall below during operation. Both over-temperature and low liquid level circuits will latch and prevent further operation of the bath until the fault is removed. Bath rests on adjustable leveling feet. All electronics are mounted on a sliding tray for easy access. Includes thermometer holder and seven plastic port covers with handles.
