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
