HKV3000
and HKV4000 High Temperature Kinematic Viscosity Baths
Constant temperature bath series with advanced temperature control circuitry
and integrated timing features for convenient, accurate glass capillary
viscometry determinations. Microprocessor PID circuitry assures precise,
reliable temperature control within ASTM specified tolerances throughout the
operating range of the bath. Simple push-button controls and dual digital
displays permit easy setting and monitoring of bath temperature. Two place
calibration offset capability is provided. Baths accommodate seven glass
capillary viscometers of various types. Viewing the viscometers is made easy
by glare-free fluorescent illumination inside the bath and a baffle that
provides a background for easy viewing. Temperature control uniformity is
assured by means of motorized stirrer which provides complete circulation
without turbulence. 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 additional cost.
Contact your Koehler Customer Service representative for more information.
Integrated Timing Features — HKV3000 incorporates seven digital timers
on the front control panel for convenient timing and monitoring of the efflux
interval for each viscometer. On HKV4000, the user can enter the viscosity
constant for each viscometer on the front LCD control/display, and then get
the test result in both efflux time and viscosity units automatically after
stopping each timer. All timing functions on both models are displayed in
0.01 second resolution and are accurate within 0.01%.
Bath Construction and Safety Features — Bath chamber is a clear Pyrex
vessel enclosed in a polyester-epoxy finished steel housing. Top working
surface has seven 2" (51mm) viscometer ports and is constructed of
stainless steel for easy cleaning. 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 over-temperature
condition or disconnection of the primary probe. For added safety, a
redundant adjustable controller with separate sensor probe interrupts power
if an over-temperature 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. Bath rests on adjustable
leveling feet. All electronics are mounted on a sliding tray for easy access.
Includes thermometer holder and seven plastic port covers with handles.
