Water bath for penetration tests

Main features
  • Great accuracy - PID control of bath temperature (not of chiller temperature)
  • Immersion PT100 probe included
  • Easy to set up and use
  • Fast heating and cooling
  • Minimum power and water consumption
  • Chiller is not mandatory - only for low temperatures

General description
General description
This water bath is specifically designed for penetration tests of bituminous materials.
It includes heating elements whose effect is compensated by a cooling coil that can be connected to mains water, with minimum water consumption.

The digital thermoregulator, with 0.1°C accuracy, features a PT100 immersion probe which can be placed close to the test specimen or anywhere inside the bath.
This grants a highly accurate PID control, overcoming traditional systems in which the temperature is measured in an external water chiller, therefore not representing the real bath temperature. 

Penetration tests are typically performed at 25°C, however special test conditions may occur, in which case the cooling coil can be connected to an external chiller (see accessories) for bath temperatures down to 5°C ± 0.1 °C.
The chiller is also useful in cases of very hot environments in which mains water temperature is higher than 25°C.
