The main functions and features
1,The instrument is completely according to national standard design research and development, for the domestic initiative, can accurate detection of transformer oil, turbine oil, fuel oil products such asacid number of automatic test equipment.
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, reduce operator contact sample and reagent, the maximum guarantee its safety.
3,Measuring instrument automatically deducted from the alcohol background value and the background value indicator, the result more accurate.
4,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.
5,The equipment startup  can be measured in 1 ~ 8 sample, convenient operation, high efficiency.
