Saybolt Viscosity Bath ( SV4000 )
Test Method
Determines the time required for 60mL of sample to flow through a calibrated
orifice under precisely controlled conditions. Saybolt Universal Seconds (SUS) is
the standard measurement for lubricants, insulating oils and lighter fuel grades,
and Saybolt Furol Seconds (SFS) is used for heavier oils and bitumens.
SV3000 Saybolt Viscosity Bath and
New SV4000 Saybolt Viscosity Bath
for Automatic Viscosity Timing
• Microprocessor control of temperature between ambient and 240°C (464°F)
• Four tube capacity
• Dual digital displays show setpoint and actual temperature
• Selectable temperature scale - Celsius or Fahrenheit
• Automatic timing option for simplified, accurate measurement of efflux times
• Conforms to ASTM D88, D244, E102, and related specifications
Constant temperature bath with available automatic timing feature for viscosity
determinations using Saybolt viscometer tubes and orifices. Microprocessor
PID circuitry assures precise 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 is provided. Accommodates four
viscometers and four 60mL receiving flasks. Sliding draft shields and a
chemical-resistant alignment plate facilitate handling of the flasks, and
glare-free fluorescent back-lighting is provided for easy viewing of the samples.
Communications software (RS232, etc.) ramp-to-set, and other enhanced
features are available at additional cost. Contact your Koehler representative
for additional information.
Automatic Timing Option - At the push of a button, the automatic timer starts
the sample flow, senses the 60mL end point, and digitally records and displays
the efflux time in 0.1 seconds resolution with an accuracy of 0.05%.
Automatic timing improves testing accuracy and convenience, eliminating the
chain and cork assembly and the need to manually time each sample. Timer
installation is available in any configuration from 1 to 4 positions.
Bath Construction and Safety Features - Insulated bath interior is constructed
entirely of heavy gauge stainless steel. A built-in overflow pipe and drain valve
simplifies filling of the bath fluid to the proper level. Chemical resistant top
plate provides excellent insulation and is easily removed to allow for cleaning
of the bath interior. A cooling coil for tap water or refrigerated coolant is
provided for operation at near-ambient temperatures. Steel cabinet has
leveling feet and a chemical resistant polyurethane-epoxy finish.
