An optical density sensor protective casing and an optical density testing device. The protective casing comprises an outer cover (1) and a bubble isolation shield (2). The bubble isolation shield (2) is embedded into the inner side of the outer cover (1), Convection holes (11) are formed in the outer cover (1). A liquid intake hole (23) is formed in the bubble isolation shield (2). The optical density device comprises the protective casing. A sensor main body is protected by arranging the protective casing. In one aspect, the sensor main body is prevented from being damaged due to collision or squeeze to the sensor main body, thereby prolonging the service life of the sensor main body; in another aspect, a solution to be tested on the inner side of the protective casing tends to be still, thereby improving the precision of the testing result. In addition, an air hole baffle plate (7) is disposed on the outer side of the outer cover (1) to prevent the solution to be tested from directly entering a testing area in a pouring process, and dust and pollutants that affect the precision of the testing result are prevented from entering the testing area, thereby ensuring the reliability of the testing result.
