|Supply Ability:||10 Set/Sets per Month acid value test|
Quality acid value test assurance laboratory measuring instrument transformer oil acidity analysis
Instrument using the powerful function of a new generation of processors and new peripheral circuit, the measurement precision, high positioning accuracy, accurate and reliable of titration end point and good repeatability of experimental results.
Basically has the following characteristics:
1.using 320 x240 graphic dot matrix liquid crystal display screen, full screen, touch keys, friendly man-machine interface;
2.using neutralization titration principle, use microcomputer to control automatically add liquid at room temperature, and titration, stirring, judge titration end point, LCD screen display and can print test results.
3.color sensor coordinate titration end point detection, judgment and reliable end conditions.
4.don't need to waste liquor cup.
5.extract and neutralization liquid by a peristaltic pump control, high measuring accuracy.
6.history inquiry, instruments and automatic memory function, with the result of the experiment time automatic storage of record, and is not lost the data after power off, can be stored for more than 10 years, for later queries to print.
7.calendar clock, temperature compensation, as accurate, record the date and time, determination in power to run more than 10 years;
8.with special reagent bottle holding extract and neutralization liquid, reagent in use process not exposed to air, avoid the influence of solvent evaporation and CO2 in the air; Users don't have to hand contact with solvents, reducing the organic solvents and chemicals to the harm of human body.
9.the equipment is simple operation, using large screen LCD and Chinese menu options, users only need to choose the menu function, according to the relevant data of the screen prompts, the instrument can automatically complete the determination of acid value.
10.the tester still can choose according to need only one sample or continuous measurement of 2-6 sample.
11.convenient communication with the computer with RS232 interface.
12.micro printer, thermal makes printing more beautiful and more quickly, with offline print function.

1.the neutralization liquid droplet, slow or little.
a.Possible and liquid bottle cap not tighten, air leakage. Tighten the lid.
b.Likely due to not completely clean, make the neutralization titration needle clogging
Replace # 4.5 needles, adjust the tilt Angle of the needle, the droplet number detection accuracy.
2.low acid value oil test results appear error 0.0001 mgKOH/g or phenomenon.
Solution: need to blank experiment. To ensure that the blank experiment must be accurate.
