KOEHLER K22753 Refrigerated Kinematic Viscosity Bath. 115V - P4487-1


KOEHLER K22753 Refrigerated Kinematic Viscosity Bath, 115V/60Hz. Refrigerated constant temperature bath with improvements in operating features, safety and cabinetry. Advanced temperature control circuitry includes microprocessor PID design and two decimal calibration offset. Simple pushbutton controls and dual digital displays permit easy setting and monitoring of bath temperature. Bath accommodates four glass capillary viscometers using 2" (51mm) round holders (rectangular ports are available on special order). Bath medium is contained in a clear, evacuated Dewar flask and glare-free fluorescent backlighting provides excellent visibility when working with the viscometers.

The LKV3000 model operates at temperatures from ambient to -30 °C (-22 °F), exceeding ASTM temperature control accuracy and uniformity requirements throughout the operating range. Air-cooled hermetic compressors provide efficient operation with the use of CFC-free refrigerants.

Insulated steel cabinet has an attractive polyester-epoxy finish and is mounted on adjustable leveling feet. Chemical resistant working (top) surface has four round ports for 2" (51mm) viscometer holders and one port for a thermometer holder. Front viewing window provides clear, distortion-free visibility. Microprocessor controller incorporates circuitry that interrupts power to the heater in the event of an overtemperature condition or disconnection of the primary probe. A redundant adjustable controller and sensor probe provide added overtemperature protection, and an integrated low liquid level sensor cuts power to the heaters if the bath liquid is not filled to the proper level or falls below during operation. Both overtemperature and low liquid level circuits will latch and prevent further operation of the bath until the fault is removed. Included Accessories: Four (4) plastic viscometer port covers with handles and thermometer holder. Conforms to the specifications of: ASTM D445, D2532, D6074, D6158; IP 71; ISO 3104; DIN 51550; FTM 791-305. Dimensions: 42 Cu. ft. Shipping Weight: 300 lbs (136kg).
