JK-1 Automatic petroleum products reflux method acid number determinator (fire resistant oil,turbine oil special)
The main functions and features
  1,JK-1 Automatic petroleum products reflux method acid number test instrument. According to the urgent requirements of the market,the instrument is completely according to GB/T7599-87 standard design research and development, for the domestic initiative, can accurate detection of transformer oil acid number of automatic test equipment. The instrument in improving the efficiency and test accuracy meanwhile,reduce operator contact sample and reagent, the maximum guarantee its safety.
  2,Without manual weighing, need to place the sample in sample cup, the device will automatically sample, heated to reflux, determination, eliminate waste, the results show print operation.
  3,Measuring instrument automatically deducted from the alcohol background value and the background value indicator, the result more accurate.The equipment startup  can be measured in one sample, convenient operation, high efficiency.Instrument calibration instrument equipped with standard acid and calibration process, the user may at any time on the instrument and the neutralizing liquid for calibration, overcomes the defects of the neutralizing liquid concentration change, improve the reliability of measurement results.
