Automatic acid number tester (Reflux method)
Scope
This instrument with ATMEL microprocessor core, mechanical, optoelectronic, electrochemical and micro-detection technology in one, using the most advanced digital optical detection system, automatic completion determining transformer oil acid value, the experimental results to standardize the format automatically printouts. The instrument reasonable structure, stable performance, simple operation, is an ideal detection equipment.
Features
1, the instrument is fully in accordance with GB / T7599-87 standard design and development, for domestic initiative, can accurately detect transformer oil, turbine oil, fuel oil and other petroleum products, anti-acid number of automatic test equipment.
2, no manual weighing just a sample placed in a specimen cup, the device will automatically injections, heated to reflux, determined to exclude waste, print the results display and other operations, reduce operator exposure sample and reagent, maximize the protection of their personal safety.
3, measurement instrument automatically deducted ethanol indicator background value and the background value, the result is more accurate.
4, instrument calibration instrument equipped with standard acid and calibration procedures, the user can at any time and in liquid instruments and calibration, and the solution used to overcome the changes in the concentration of defects and improve the reliability of test results.
5, the start time can be measured from 1 to 3 samples, easy to use, high efficiency
6, automatic detection end of the experiment: The color indicator measurement, automatic detection of the end of the color (color value can be set), and the same human judgment. (Recognizes three indicator)
Technical Parameters
1, applies to GB / T7599-87, GB / T264-83 standard.
2, the test range: 0.002 ~ 1mg KOH / g
3, the measurement error: ≤ ± 0.005 mg KOH / g
5, Temperature: 10 ℃ ~ 45 ℃
6, for humidity: <85% RH
7, power supply: AC220V / 50Hz
8, Power: 500W
