Device for testing rate of infiltrating pole piece by electrolyte

The utility model discloses a device for testing the rate of infiltrating a pole piece by electrolyte. The device comprises a base, a supporting rod, a fixed part, a sliding part, an adjusting assembly, a limiting assembly and a capillary tube. The supporting rod is fixed on the base; the fixing piece is fixedly arranged on the supporting rod; the sliding piece is arranged on the supporting rod in a sliding mode. The adjusting assembly is used for controlling the sliding piece to move up and down along the supporting rod. The limiting assembly is used for limiting the distance between the sliding piece and the fixed piece and the distance between the sliding piece and the base. A clamping piece and a scale are arranged on the sliding piece; the capillary tube is fixed on the sliding piece through the clamping piece; the device avoids the problems of inaccurate observation and low measurement precision caused by unobvious liquid level change, and is simple in structure, convenient to operate, high in test spee
