Product Description
LKV4000 Digital Refrigerated Constant Temperature Kinematic Viscosity Bath
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.

Features and Benefits
~ Improved design with enhanced performance and safety features
~ Extended range -70C (-94F) LKV4000 model
~ Microprocessor PID temperature control with two decimal calibration offset
~ Dual digital displays show setpoint and actual bath temperature
~ Selectable temperature scale - Fahrenheit or Celsius

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.

Extended range LKV4000 model operates at temperatures as low as -70C (-94F). Exceeds 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.

Bath Construction and Safety Features - 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. A redundant adjustable controller and sensor probe provide added over-temperature protection, and an integrated low liquid level sensor removes power to the heaters if the bath liquid is not filled to the proper level or falls 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.

LKV5000 Refrigerated Constant Temperature Bath with Optical Detection - Koehler LKV5000 series kinematic viscosity baths with the 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. REQUEST PRICING
