Precise and accurate temperature control

  • Temperature range: 10 °C to 150 °C*
  • Temperature accuracy: ± 0.01 °C from 10 °C to 100 °C; ± 0.03 °C from 100 °C to 150 °C
  • Meets ASTM D445 temperature sensitivity requirements for kinematic viscosity determination
  • Motor driven stirrer ensures a uniform bath temperature

Microprocessor-controlled temperature regulation & networking capabilities

  • Desired bath temperature and calibration temperatures are digitally entered on the front panel keypad
  • Integrated microprocessor automatically regulates bath temperature
  • Both target and actual bath temperatures are monitored by an RTD temperature probe and continuously displayed in °C or °F on the LCD screen
  • RS-232 and RS-485 communication ports provide data acquisition and multi-unit networking capabilities

Efficient, user-friendly design

  • Seven glass viscometer ports (each 2” in diameter) and two thermometer ports (each 0.4” in diameter) allow up to 7 simultaneous viscosity determinations**
  • Two electric heating elements quickly heat bath media to the selected temperature
  • Stainless steel baffle provides a plain reflective viewing background
  • Integrated stainless steel cooling coil allows connection to tap or recirculating water chiller for temperatures slightly above or below ambient. An external thermoelectric bath cooler is also available.
  • Convenient drawer provides easy access to electrical controls
  • Capable of using water or oil as bath medium

Safe operation

  • Bath thermistor senses over-temperature fault and removes power
  • Thermistor disconnection results in removal of bath heater power
  • Liquid level sensor prevents operation if bath liquid is not at a safe operating level

Reliable performance

  • Well tested CANNON bath platform offers reliability and dependable support
  • All wetted components are manufactured from high quality stainless steel or glass
  • The heavy duty aluminum frame offers a corrosion-resistant epoxy finish

* Test temperatures < 40 °C and high ambient temperature test environments require an optional bath cooler
** Other port configurations are available as a special order
