Koehler Refrigerated Kinematic Viscosity Baths - LKV3000 - K22754

New refrigerated constant temperature bath series with improvements in operating features, safety and cabinetry. Advanced temperature control circuitry includes microprocessor PID design and two decimal calibration offset. Simple push-button controls and dual digital displays permit easy setting and monitoring of bath temperature. Baths accommodate four glass capillary viscometers using 2 IN (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. Standard LKV3000 model operates at temperatures from ambient to -30ºC (-22ºF). Extended range LKV4000 model operates at temperatures as low as -70ºC (-94ºF). Both models exceed 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 IN (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 over-temperature condition or disconnection of the primary probe. Included Accessories: Four (4) Delrin® 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.
