The utility model discloses a take bacterial colony diameter dipperstick of angle and length survey function, it includes and circular shape blade (1) is equipped with fungus cake position circle (3) in the centre of a circle position of this blade (1), be the center with blade (1) the centre of a circle, be a meter style of calligraphy around to and scatter the equipartition and be equipped with eight scale marks, have at least in eight scale marks to be equipped with on the scale mark and measure diameter scale (2), laid along blade (1) periphery ring and measured angle scale (4). The utility model discloses a having overcome and having measured in the past that bacterial colony diameter step is loaded down with trivial details, the operation is inconvenient, error increase scheduling problem, once only can measure the diameter of bacterial colony all directions, a take bacterial colony diameter dipperstick of angle and length survey function still has the function of measuring the angle in addition.
