They have the advantages of high sensitivity, fast electrolysis speed, short equilibration time, accurate blank deduction, and accurate and reliable analysis results. Applications in petroleum, chemical, power, environmental protection, scientific research and other departments. Features
Control system: SCM and computer compound control.
Zero point correction: The accurate software deducts the blank function, which guarantees that the blank can be accurately deducted within the 10-minute sample enrichment time.
Equilibrium point (titration endpoint) setting: Equivalent to the pH value of the product during acid-base titration, different indicators can be selected. This function can improve the adaptability to different sensitivity reagents, ensuring that the instrument is used in various All reagents can be adjusted to the optimal measurement sensitive area for analysis.
Communication function: It can be connected to an external balance, and can communicate with a computer, store a large amount of data in the computer, and control the instrument with a computer for easy operation.
Analysis accuracy setting function: According to the analysis requirements of different measurement samples, users can freely choose the analysis speed and measurement accuracy.
Analysis result storage function: can store 100 measurement data.
Reagent replacement prompt function: It can prompt the user to replace the reagent that is about to expire.
Fault self-diagnostic function: When there is a fault in the electrolysis part or measurement part of the instrument, the fault is automatically prompted, which is convenient for the user to diagnose the fault. Technical Parameters
