PT-D1177-4A Engine Coolant Automatic freezing point tester is designed and manufactured according to the requirements of ASTM D1177 and SH/T0090 “Determination of Freezing Point of Engine Coolant”. Under specified cooling conditions, when the test sample is cooled to a certain temperature, solids precipitate out, and the temperature rises again, the highest temperature reached is the freezing point. It is suitable for determining the freezing point of engine coolant and engine concentrate, and is widely used in petroleum, chemical, power, commodity inspection, universities, scientific research and other departments.
- The complete machine includes a cold bath refrigeration system, a bath heating system, a motor stirring system, and a touch screen human-machine interface system.
- 7-inch color LCD touchscreen, intuitive and convenient operation with clear display.
- The instrument adopts an embedded system, and the test process is automatically detected.
- The instrument uses a dual-compressor refrigeration system, and the lowest temperature of the bath can reach -70℃.
- The screen displays the sample temperature and the temperature in the bath in real time.
- You can set the expected freezing point at will, save the test results yourself, and view historical data.
