HKV4000 High Temperature Kinematic Viscosity Bath with Integrated Digital Timing

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 an additional cost.  

Integrated Timing Features -The user can enter the viscosity constant for each viscometer on the front Touch Screen Control Panel, and then get the test result in both efflux time and viscosity units automatically after stopping each timer. Timing function is displayed in 0.01 second resolution and is accurate within 0.01%.  


Bath Construction and Safety Features - The bath chamber is a clear borosilicate glass vessel enclosed in a polyester-epoxy finished steel housing. Top working surface has seven 2" (51mm) viscometer ports. 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 overtemperature condition or disconnection of the primary probe. For added safety, an adjustable redundant controller with separate sensor probe interrupts power if an overtemperature 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.
