Power supply: 220V, 50 HZ; Third, the instrument composition: 陶瓷砖抗冻性测定仪由冷冻试验箱、贮水箱（带温控功能）及进排水系统、控温与自动控制系统三部份组成。 SQ007 ceramic tile frost resistance tester consists of three parts: freezing test box, water storage tank (with temperature control function), inlet and drainage system, temperature control and automatic control system. The working principle of this instrument is designed and implemented in accordance with GB / 3810.12-2006 national standard requirements. Set the number of test cycles (100 times) of the electronic counter according to the test requirements.Put the sample in the test area and cover the cover.Refrigerate the test area to -5˚C and keep it for 15 minutes. Turn on the water pump to spray water on the sample to increase the test temperature to + 5˚C and keep it for 15 minutes. The counter counts once. Set the electronic counter according to the test requirements. Determine the number of test cycles (100 times).Automatically perform the above-mentioned cycle test and report a warning after the test.Test water is recycled.
