Acid-base value Meter

Be used to test total lubricant acid number and total base number of combustion engine.

Be applicable to total lubricant acid number and total base number of combustion engine.

Testing range: acid number 0~2.5mgKOH/g

 Total base number 0~20mgKOH/g

Accuracy: meet GB/T264

Supply voltage: 220V AC

External dimension: 340mm×165mm×115mm

Weight: 4kg

a. Configuration

It is composed of host machine, electrodes, heater, sample cup, PC and relevant software.

b. Technical Principles 

Under the control of controlling circuit, the electrode-inspirited signals produces scanned voltage signals in triple-electrode system, which is immerged in the sample solution. It will be read out by controlling circuit after I/V conversion and wave-straining as well as A/D switch. Integrating with the scanned supply voltage, the testing result is calculated and displayed according to electrochemistry theory.
