1. Simple Introduction
DWC 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.
2. Follow Test Standards:
ASTM, E23-02a, En10045, ISO83,GB/T229-2009
3.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
