Spesifikasi Koehler K22752-OS LKV5000 Refrigerated Kinematic Viscosity Bath with Optical Flow Detection System



Koehler LKV5000 series kinematic viscosity baths with optical flow detection system provides automatic viscosity measurements of petroleum and petrochemical products. Includes communication and power ports for each optical detection assembly, and can utilize up to four optical assemblies. Optical sensors and viscometer tubes to be ordered separately. The bath 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 LKV5000 operates at temperatures from ambient to -30 °C (-22 °F) or ambient to -70 °C (-94 °C), model dependent, 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.
