ND2010A typeWorking principle

Microcomputer intelligent control has achieved full automation of the measurement process, that is, automatically heating the sample to 50 ℃, naturally cooling it to 35 ℃, and then automatically placing the sample into a cold trap. When the sample temperature reaches the detection temperature, the cold bath box containing the sample is automatically tilted at 45 ℃, and the flowability freezing point of the sample is detected using red outer optical fiber cable sensing technology. The entire process of detecting the sample's solidification is * every time; This ensures that the solidification point of the sample is accurate. The program control realizes the measurement of the solidification point of the sample (i.e. the sample flows when the temperature is 2 ℃ higher than this temperature, and solidifies when the temperature is equal to this temperature); And automatically store and print records of data.
