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, it can measure the freezing point of jet fuel, engine coolant concentrate separately, it 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. The art electromagnetic stirring, no noise, low failure rate, is the preferred alternative to the traditional mechanical agitation. Technical Parameters 1. Power supply: AC 220V ± 10%; 50Hz; 2. Working cold tank: stainless steel cold tank, double vacuum glass viewing window; 3. temperature control of cold tank: +20 °C~ -70 °C; 4. Temperature accuracy: ± 0.5 °C; 5. Bath stirring: automatic stirring by motor, power 6W, 1200r / m; 6. Refrigeration system: new refrigeration compressor; 7. Display mode; LCD display 8. Ambient temperature: 30 °C; 9. Relative humidity: 85%; 10. Total power consumption: not more than 2000W.
