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.

Product Description.

  • 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 backlighting is provided for easy viewing of the samples.
  • Communications software (RS232, etc.) ramp-to-set, and other enhanced features are available at additional cost.

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.

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.
