Freezing Point Tester

This Automatic Engine Coolant Freezing Point Tester is automatically controlled by an industrial computer. It is simple to operate, automatically controlling, detecting, and calculating results. It automatically stops at the end of the test, and the software displays the time-temperature curve. The testing principle involves taking 75-100 ml of sample, injecting it into a test tube, placing the test tube in a cold bath for cooling, recording the sample temperature every minute, and plotting the time-temperature curve. The projection of the intersection of the cooling curve and the crystallization curve onto the vertical axis is the freezing point of the sample .

 

1. Color touch screen with simple and intuitive menus, usable without training.
2. The traditional electromagnetic stirring method has been changed, and an imported motor has been used instead .
3. Use a glass Dewar flask for a cold bath to ensure that the cold air is not lost .
4. An embedded system design is adopted, enabling automated detection throughout the entire testing process.
5. The instrument uses imported dual-compressor cascade refrigeration with environmentally friendly refrigerant, resulting in
fast cooling speed.
6. Made of cold-rolled steel sheet with electrostatic powder coating, it is corrosion-resistant and easy to clean.
7. The uniquely designed Dewar flask defrosting system ensures convenient observation.
