AT461 Methylene Chloride Tester is used to determine the resistance of PVC-U pipes to dichloromethane at a specified temperature. This instrument complies with the following international and industry standards. ISO: ISO 9852. GB/T: GB/T 13526. It consists of a thermostatic tank, stainless steel inner tank, fine-mesh filter, temperature control timing system, cooling system, etc. Constant test temperatures are achieved thanks to highly-efficient water circulation and precise temperature control in the inner tank. Equipped with a stainless steel folded bracket, it is more convenient for the user. Double cover design to prevent the liquid from evaporating. Minimal energy loss thanks to high-quality insulating material.
