Tergotometer Detergent Tester

The Tergotometer (or Terg-o-tometer) is a versatile laboratory-scale multiple washing machine which simulates the action of eight miniature domestic washing machines within a single bench top instrument allowing eight samples to be processed simultaneously under identical conditions of speed, time and temperature.

Any number of variables can be tested in this manner: not only the temperature, agitation speed and test period but also composition of the wash solution, degree of water hardness, pH, bleach, etc.

Typical applications include:

  • Evaluation of the effectiveness of soap, detergents, etc.
  • Washability and colour fastness of fabrics and other materials
  • Optimisation of temperature, speed and water hardness parameters
  • Routine screening for dirt removal, brightening, softening, foaming, etc.

The Tergotometer has significant advantages over the Wascator or Launderometer (or Launder-o-meter) often used for testing laundry detergents. These include:

  • Reduced quantities of test materials (fabrics and detergent) and water
  • Faster cycles times
  • Reduce footprint and noise levels, making it ideal for laboratory use (bench mounted)
  • Higher accuracy and reproducibility due to better control over equipment dimensions and test parameters
  • Data output for documentation of test parameters
  • Refrigeration capability (down to 10 degrees C)
  • Ability to modify for testing dishwasher detergents
