High Vacuum Tribometer (HVTHT)

Anton Paar’s High Vacuum Tribometer (HVTHT) has been designed to achieve controlled gaseous environments or vacuum conditions down to 10e-7mbar.

The HVTHT is a highly efficient vacuum control system, enabling users to achieve the required atmospheric condition but in a controlled manner.

The reliability of Anton Paar Tribometers has been demonstrated in more than 100 laboratories, for investigating:

  • High vacuum environment down to 10e-7mbar
  • Self-lubricating systems
  • New materials such as polymers, metals, and ceramics

Key Features

The key features of the HVTHT are as follows:

  • No parasitic friction
  • Stable contact point
  • Variable sample sizes and shapes
  • Automatic shut-off (max. track length / max. friction coefficient)
  • Testing in liquids and controlled humidity
  • Precisely calibrated friction and wear measurements
  • Powerful software package for PC
  • Testing compatible with DIN 50324, ASTM G99 and ASTM G133


  • The options available include:
  • Electrical contact resistance
  • High temperature model (1000°C max temperature)
  • Contact depth measurement
  • High speed motor (1500 rpm)
  • Range of ball/pin holders available
