DR-5型全自動低溫柔性試驗儀，是根據(jù)中華人民共和國國家標準GB/T328.14-2007建筑防水卷材試驗方法，第14部分：瀝青卷材—低溫柔性，對低溫柔性試驗裝置的要求，由我公司研制開發(fā)的一款新產(chǎn)品。儀器主機全部采用304材質(zhì)不銹鋼制作，動力源采用永磁低速電機驅(qū)動，雙動8平行排列，可同時作正、反面各五個試樣。控制器采用智能溫度控制儀、數(shù)顯時間繼電器及相關元器件?？刂破骱椭鳈C相連接部分全部采用航空插頭方式連接，該連接方式簡單、方便、安全，并且有效的節(jié)省了儀器的使用空間。DR - 5 type automatic flexible tester at low temperature, is according to the law of the People's Republic of China national standard GB/T328.14-2007 building waterproofing materials testing methods, part 14: asphalt coil - low temperature flexible, flexible test device for low temperature requirements, by a new product developed by our company. Instrument host are all made of 304 stainless steel material, power supply adopts permanent magnet low speed motor drive, double acting eight parallel arrangement, positive and negative can be made at the same time the five samples. Controller with inligent temperature control instrument, digital display time relay and related components. Host controller and the way of connecting parts are all made of air plug connection, the connection mode is simple, convenient, safe, and effective to save the instrument in the use of space

DR-5型全自動低溫柔性試驗儀是DR-3型電動數(shù)顯低溫柔性試驗儀的改款升級版，儀器采用不銹鋼制作，*的工藝保證了溫度控制精度在 ±1℃，降溫速度是普通冰柜的幾倍，zui低溫度可達-35℃。測試儀也是采用不銹鋼制作，特點：操作簡單，工作效率高。

DR - 5 type full automatic type low temperature flexible tester is DR - 3 electric digital display of low-temperature flexible tester to upgrade, the instrument adopts stainless steel, the unique technology to ensure the precision of temperature control in the ± 1 ℃, the cooling speed is several times of ordinary freezers, the lowest temperature can reach - 35 ℃. Tester is also made of stainless steel features: easy operation, high work efficiency
