Description:

1.Purpose and Characteristics:

DWC-196 Impact Test Ultra-low Temperature Chamber is a newly developed refrigeration instrument according to 

the requirements of ultra-low temperature devices in GB229-2007 "Charpy notch impact test method for metals".

It adopts liquid nitrogen refrigeration and high-precision intelligent instrument to control ultra-low temperature, 

so as to achieve automatic uniform cooling and constant temperature of the sample, which can fully meet the various 

temperature control indexes specified in the national standard GB229-2007.

Low-temperature tank is widely used in low-temperature physical and chemical tests in petrochemical, metallurgical, 

boiler and pressure vessel, steel, steel pipe, hardware, casting, pumps, valves, fasteners, vehicles and ships, machinery 

manufacturing, aerospace and scientific research industries.

The operation is simple and convenient, and the working efficiency is improved. According to the actual needs of 

customers, the same series can choose -40℃, -60℃, -80℃, -100℃, -150℃, -196℃ (liquid nitrogen) cryogenic tanks.
