Circulating Thermostat PT31

Circulating thermostat PT31 Temperature range 8-35 °C

The smallest circulation thermostat on the market

The PT31 circulation thermostat is equipped with highperformance functions. The 1.5 kg lightweight device is ideally suited for applications requiring a temperature range at a constant level. The proven Peltier technology offers process-reliable temperature control in the range from 8 °C to 35 °C. The accuracy of temperature control is ±0.2 °C.

The robust locking mechanism of the PT31 provides a sturdy connection and ensures constant temperature control of the medium. The compact and sturdy design does not require much space and can be placed anywhere in the laboratory.

Your benefits:

  • Temperature control using Peltier technology
  • Temperature range from 5 °C to 35 °C
  • Temperature accuracy of ±0.2 °C
  • Space-saving, sturdy design
  • Suitable for operation with non-flammable liquids (water or water/glycol mixture)
  • Bright, easy-to-read LCD matrix display
  • Sophisticated, easily accessible operating elements
  • Convenient connection with P8000 series polarimeters
  • Simple and plainly structured functions

Typical applications

  • Temperature control of small sample volumes in analytical laboratories, chemical laboratories, life science
  • Temperature control of refractometers, polarimeters and viscometers
  • Temperature control of cell changers in UV / VIS device
  • Applications in the laboratory that require a variable and space-saving placement of the thermostat

Operating elements

The PT31 has a quick and easy to achieve operational readiness. The sophisticated operating elements are easily accessible and allow the temperature to be set with just a few inputs. A menu with easy-to-understand navigation is used for set-up. The LCD matrix has a bright, easy-to-read display. Temperature settings as well as heating and cooling functions are displayed in a clearly arranged manner. The interface facilitates convenient control with our P8000 series polarimeters.

Temperature control of Abbe Refractometer AR4

The PT31 circulation thermostat is often used for the sample temperature control of Refractometers. The Abbe refractometer AR4 can achieve highly accurate and extremely reproducible measurement results completely independent of the ambient temperatures. PT31 circulation thermostat is extremely small and can be very easily connected to all water-temperable refractometers.

Temperature control of Polarimeter P8000-T

When used in combination with polarimeters, the PT31 circulation thermostat ensures uniform temperature control of the samples to be measured. This enables highprecision and reproducible measurements, such as those prescribed by different standards in the pharmaceutical industry at 20 °C or 25 °C.
