Abstract

The invention discloses an online control measurement device for concentration of oxalic acid liquid medicine. The device comprises a flushing branch, an air charging branch, an oxalic acid extractionbranch, a liquid discharging branch, a container, a conductivity meter, a heating bar and a thermocouple. The flushing branch, the air charging branch, the oxalic acid extraction branch and the liquid discharging branch communicate with the container. The conductivity meter, the heating bar and the thermocouple are arranged in the container. According to the invention, the production cost is low;the device can be used for most users who need to measure the concentration of the oxalic acid and carry out real-time supplementation without high device cost; manual titration measurement is not required, so workers are prevented from suffering from dangers; and manual cost is reduced.
