从China供应商批发进口Engine Coolant Freezing Point Tester — FOB条款

Scope Engine coolant freezing point tester in accordance with the national standard gb / t2430 "determination of the freezing point of jet fuel, " requires the state petroleum and chemical industry standard sh / t0090 "engine coolant freezing point determination" provides design and manufacture. Choose a different configuration, measuring jet fuel, engine coolant concentrate its freezing point and other indicators may be used separately, is a multi-purpose freezing point tester. Features 1. Double vacuum glass observation window, real-time observation of samples during operation; 2. Using imported compressor refrigeration the cascade technology can reach -70 ° cold bath, noise; 3. Using pid control techniques, temperature control, temperature control accuracy of ± 0.5 °c4, engine coolant freezing point tester using state-of 4.
