。[Scope of claim for utility model registration] A detection end for detecting sludge concentration in sample water containing activated sludge is raised and lowered, and a recording section records the sludge concentration distribution based on the detected concentration and water depth. In the sludge concentration distribution measuring device, the detection end is configured with an ultrasonic concentration sensor and an optical concentration sensor that are arranged to measure the sludge concentration of water sampled at the same depth, and the ultrasonic concentration sensor Input each output signal of the sensor and the optical concentration sensor, compare the detected concentration corresponding to this output signal with a preset set concentration, and if both detected concentrations are higher than the set concentration, the ultrasonic concentration sensor and a signal selection section that outputs a signal corresponding to the detected concentration to the recording section, and outputs a signal corresponding to the detected concentration of the optical density sensor to the recording section when any detected concentration is lower than the set concentration. A sludge concentration distribution measuring device featuring:
