This instrument is strictly designed and manufactured in accordance with the freezing point determination method of the Chinese Pharmacopoeia. It measures the highest temperature at which a drug remains unchanged for a short period of time when it solidifies from liquid to solid. Some drugs have a certain freezing point. When the purity changes, the freezing point also changes accordingly. Determining the freezing point can distinguish or check the purity of the drug. The insulated dewar flask is used for transparent observation, allowing for transparent observation of the freezing point during sample testing. It is made of high-quality cold-rolled steel plate and treated with electrostatic powder coating on the surface. Main features： 1.    Color Chinese and English touch screen operation, micro single-chip microcomputer intelligent temperature control, and automatic detection of drug freezing point； 2.   The working state is dynamically simulated graphically, and the test process is reproduced on the screen ； 3.    It features automatic detection, accurate test results with good repeatability, stability and reliability, simple operation, and the ability to print experimental results； 4．High-performance compressor refrigeration, fast cooling speed and long service life ； 5． The fault diagnosis function automatically prompts to prevent measurement errors； 6.   …
