KV5000
Kinematic Viscosity Bath
New Koehler KV5000 series kinematic viscosity baths with optical sensors
provide automatic viscosity measurement of petroleum products. Each viscosity
bath includes communication and power ports for each optical sensor in
addition to the full operational features of the modified KV4000 series
baths. Each KV5000 bath can utilize up to five optical sensors (K23780).
Viscometer tubes are easily installed and removed, avoiding sample contact
with the optical detection system. Rugged construction of optical sensors
prevents corrosion and provides for easy cleaning.
Constant temperature bath 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 five 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 — KV5000 utilizes software to allow the user
can enter the viscosity constant for each viscometer and then get the test
result in both efflux time and viscosity units automatically.
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
overtemperature condition or disconnection of the primary probe. For added
safety, a redundant adjustable 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 overtemperature 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.
