SLNH-230 Cold Resistance Tester

Overview.

SLNH-230 cold coefficient tester can be used to determine the rubber or film specimens at room temperature and frozen by a certain load, according to the specimen extension length changes and calculate the cold coefficient, or with the required load to the specimen stretched to the same length and calculate the length of the increase in the value of the compression cold coefficient determination. Various technical indicators in line with HG/T3867-2008 or GB/T6035-1985 vulcanized rubber tensile cold coefficient of determination, "HG/T3866-2008 vulcanized rubber compression cold coefficient of determination of chemical standards. SLNH-230 cold coefficient of determination of the use of refrigerant compression cooling, change the previous dry ice and liquid nitrogen cooling method. and liquid nitrogen for cooling, the container with alcohol, so that the surrounding temperature is more uniform, falling temperature faster, saving time, reducing the test energy consumption, reduce test costs.
