TV-22 Viscometer

Feature

• Torque balance servo system
  The TV-22/33 employs the "zero method" of measurement structured on a torque balance servo system. Normally found in upper-end rheometers, this system provides for a wide dynamic range, superior linearity, and multi-range capability. Multi-range function The TV-22/33's multi-range function permits a single model to cover a wide range of measurement compared to conventional type viscometers. One Model TV-22L/33L, for example, provides measurement ranges from "M" to "5M" while the Model TV-22H/33H covers measurements over the "H" through "U" ranges.
• Zero • span setting function
  Calibration allows the viscometer to be used at accuracies higher than catalog values and compensates for unit-to-unit variances.
• Programmable measurement function (TV-33)
  The instrument provides programmable measurement capability involving a maximum of 40 speed step changes (up to 5 pattern settings).
• Thixotropic coefficients measurement
  function (TV-33) This function calculates and displays the ratio of two viscosity values as measured in the programmed measurement mode. (rotation speed can be freely set)
• Pivotless mechanism
  A pivotless arrangement which employs a flexible hinge (flat spring coupling) replaces the traditional pivot and jewel bearing mechanism. This eliminates parts wear and insures that the instrument's high initial repeatability is maintained over time.
• Omni-directional external force limiter
  Excessive external forces acting on the rotor connection are isolated with the aid of an omni-directional external force limiter which protects the inner mechanism for greatly enhanced durability.
• Autostop function
  Measurement is automatically terminated at a prescribed time or when the liquid measured attains a preset viscosity. (manual measurement mode only)
• Remote control function
  To start and stop the main unit can be operated by outer signal (dry contact). And Using out put signal (open collector), the situation of viscometer can be confirmed by buzzer and lamp.
• Preheat function
  Viscosity measurement can be automatically started at a preselected time to allow for a preheat "waiting" period.
• One touch rotor mounting
  A rod insertion system is employed which simplifies rotor mounting and removal compared to conventional threaded methods (Model TVB-22/33).
• Data interchangeability
  Data is cross compatible with that of Model B (spindle type) and Model E(cone-plate type) viscometers, DV-100/DV-200 digital viscometers and Model R viscometers. Related standards: ISO2555, JIS7117-1 (Model TVB); ISO3219, JIS7117-2 (Model TVE); etc.
• Temperature measurement function
  Temperature probe-equipped models are available. The cone plate type can measure the temperature of circulating water in a sample cup.
• Data recording
  A calendar is mounted in the main unit. Data, measuring date and starting time can be documented using a printer (option) with digital output cable (option) connection or pen recorder, etc., with an analog output cable (option).
