The content of total polar substances in edible oil (%%TPM) can be used as a good index to measure the quality of oil. Therefore, in many countries, the content of total polar substances in edible oil frying is 24% ~ 30% as the legal limit. China attaches great importance to the safety of frying oil, and promulgated the first hygienic standard for frying edible vegetable oil as early as 1986. 1996 First revision and supplement; The second revision in 2003 was GB7 102. 1-2003, which stipulated that the content of polar components was ≤ 27%.

CSY-SDC frying oil quality quick detector can quickly detect the total content of polar components in oil. The hand-held inferior oil detector developed and produced by Shenzhen Fenyan Instrument Manufacturing Co., Ltd. can accurately judge the percentage of polar substances and nonpolar substances by measuring the difference in electricity prices between the two poles, and can accurately calculate the content of polar substances in a few seconds. It has the advantages of simple operation, high speed, no damage and no solvent. At the same time, due to the influence of temperature on the content of polar substances, the hand-held inferior oil detector can simultaneously display the temperature value. The product also obtained the national patent certificate number of intellectual property protection: 201630160172.5, and the invention patent number: 20 1620525800. X
