Features
1. The automatic freezing point analyzer is composed of refrigeration system, industrial control upper computer control system, embedded hardware control system, mechanical and electrical mixing system, cold bath test observation system, frame structure shell system, etc.
2. The refrigeration system adopts the overlapping refrigeration, cold bath minimum up to -70℃, through the condensing tube, temperature sensor, bath stirring device, heating tube and other components to make the temperature control accuracy of ±1℃, meeting the freezing point test requirements specified in the corresponding standards.
3. The cold bath device of this instrument can simultaneously carry out parallel test of two test tubes; stainless steel cooling bath inlaid with multi-layer interior heating glass windows, good thermal insulation performance, no dew or frost, excellent performance.
4. A test stirring device with a special motor driven up and down linear motion
5. The instrument can automatically capture the freezing point, according to the return temperature characteristics of the freezing point, the changes can be seen intuitively on the curve of the main interface
6. The cold bath temperature of the instrument is 28℃ less than the preset freezing point, and the system is automatically controlled without manual intervention.
