Abstract
The invention relates to a device and a method for measuring the content of lead carbonate in a storage battery polar plate. The device comprises a gas gathering element, a burette, a first container and a second container, wherein the gas gathering element is provided with a funnel-shaped opening, and the upper ends of the first container and the second container are opened; the first container is placed in the receiving cavity of the second container; the opening of the second container is higher than that of the first container; one end of the funnel-shaped opening of the gas gathering element is backed off at the opening of the first container; a gap is reserved between the funnel-shaped opening and the opening of the first container; and the burette is communicated with the gas gathering element. In the device and the method for measuring the content of lead carbonate, unrelated gas is removed before adding an acid liquor to react (for example, pure water is filled into the measuring device so that the pure water rises over the opening of the first container and the funnel-shaped opening of the gas gathering element, thereby removing gas between polar plate powders), so that the inference of the unrelated gas on the measurement result is avoided, and the accuracy of measurement is improved.
