Pendulum Damping Tester, Model 299/300 (REFERENCE CLASS)

A standardised method for determining mechanical damping
properties of paints, varnishes and similar coatings

The stand appliance consists of a support and a base plate with levelling screws. The support holds a specimen holder for
test panels measuring up to 250 x 100 x 15 mm. The instrument is protected against dust and draught by an acrylic
glass hood which has openings for positioning the specimens.
The pendulum damping tester is operated from a control terminal located outside the housing.
As optional accessories two different pendulums with yokes, made of rust-resistant steel, are available:

  • Pendulum in accordance with König, conforming to DIN 53 157
  • Pendulum in accordance with Persoz, conforming to NF T 30-016

The pendulum is automatically adjusted, avoiding timeconsuming fine-setting of the light barrier.
Two different measuring modules are available:

Basic version; The excursion of the pendulum is effected manually by way of a lever mechanism.
The pendulum is actuated by way of cable release.

Automatic version; The excursion and actuation of the pendulum are effected automatically.
The automatic version offers the following additional advantages:

  • user-friendly operation
  • consistent test results
  • simple change of pendulum type

In both versions the pendulum type is entered on the control terminal.
Readings on the 4-digit LC display show alternatively.

  • the number of oscillations
  • the length of test, or the period of oscillation
