Hello, this volumetric titration moisture analyzer adopts Vantone titration components, and Karl Fischer reagent is pumped by piston injection pump and injected into titration cell. If Karl Fischer reagent cannot be injected, please check whether there is reagent (dark color) in the burette and whether the piston is moving when the liquid is sucked or injected. If the piston is moving and no reagent enters the measuring glass tube, it should be liquid leakage or there is no reagent in the reagent bottle. If there is reagent in the measuring glass tube, the piston is moving. But it didn't enter the titration cell, so the pipe may be leaking. Look at that. If the piston does not move when injecting or sucking liquid, and sometimes the instrument makes abnormal noise, it should be that the hardware of the instrument is faulty, so please ask the supplier to repair it.
AKF series volumetric Karl Fischer moisture analyzer adopts how fault diagnosis function and patented high-precision metering device. The failure rate is much lower than that of similar products, so it is generally impossible to have such problems.
