-60°C~+30°C Low Temperature Chamber for Metal Specimen Impact Test
Application:
CDW Series Temperature Chamber is designed according to the standard
of 'Charpy Notch Impact Test Method for Metal Materials. It adopts
compressor cooling technology, which is made up of two sections
(Low temperature grade and high temperature grade).
It utilizes the heat balance principle and cycle stirring method to
realize the constant temperature cooling to impact specimen with
the reliable performance.
Test Standards:
ASTM, E23-02a, En10045, ISO83,GB/T229-2009
Features:
1) Imported compressor, DANFUS valve, imported
evaporation-condensation machine;
2) Controlled by intellligent instrument, digital presentation
temperature value, automatic control temperature, automatic time
and alarm.
3) High security, refrigerate fast, large volume
