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. 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. Work the cold tank: stainless steel cold tank, double vacuum glass viewing window; 3. Cold trough temperature: +20 °c~ -70 °c; 4. Temperature accuracy: ± 0.5 °c; 5. Bath agitation: automatic stirring motor, power 6w, 1200r / m; 6. Refrigeration system: new refrigeration compressor; 7. Sample stirring: electromagnetic stirring, 0 to 120 beats / minute, continuously adjustable; 8. Ambient temperature: 30 °c; 9. Relative humidity: 85%; 10. Total power consumption: not more than 2000w.
