TE-1500 Sub-Zero Constant Temperature Bath

CANNON product

ASTM D445/D446, ISO 3104/3105. The TE-1500 series constant temperature bath, with integrated thermoelectric cooling, accommodates viscometer tubes requiring a bath depth up to 12″ and provides reliable temperature control from −30 °C to 10 °C. 

Category: Tag:


The thermoelectrically-cooled TE-1500 provides rock-steady cooling to -30°C using Peltier cell technology. Cooling fans and front panel controls are the only moving parts in this advanced design. A four-pane frost-free viewing window and twin fluorescent lamps provide excellent visibility and illumination within the bath.

Features & Benefits

Precise and accurate temperature control

  • Temperature range: −30 °C to 10 °C ± 0.01 °C
  • Meets ASTM D445 temperature sensitivity requirements for low temperature kinematic viscosity
  • Temperature selection is variable between −30 °C and 10 °C or selectable at eight pre-set temperatures (10 °C, 0 °C, −5 ° C,
    −10 °C, −15 °C, −20 °C, −25 °C and −30 °C)

Compact, user-friendly design

  • Environmentally-friendly, integrated thermoelectric air cooling requires no external refrigeration or air/water heat exhangers
  • Two glass vicometer ports (each 2″ in diameter) and one thermometer port (0.4″ in diamter) allow up to 2 simultaneous viscosity determinations
  • Baffle within the aluminum bath vessel facilitates circulation for uniform bath temerature and provides a plain viewing background
  • Frost-free viewing window and internal illumination proves excellent visibility within the bath

Safe operation

  • Bath thermistor senses over-temperature fault and removes power
  • Thermistor disconnection results in removal of bath heater power

Reliable performance

  • Well tested CANNON bath platform offers reliability and dependable support
  • The heavy duty aluminum frame offers a corrosion-resistant epoxy finish
