PROBLEM TO BE SOLVED: To provide a portable liquid detection and filtration device.;SOLUTION: A portable liquid detection and filtration device includes a first vessel 10, at least one sensor 20, at least one actuator device 60, and a filter unit 30. The first vessel comprises a communication passage 11 used as a vessel of detection liquid. The at least one sensor is installed in the communication passage and detects the detection liquid in the first vessel. The at least one actuator device communicates with the communication passage and transports the detection liquid. The filter unit communicates with the communication passage and is adjacent to a fluid transport device, and filters the detection liquid transported by the actuator device. The sensor detects the detection liquid in the first vessel, and when the sensor detects that an observed value of the detection liquid is abnormal, the sensor transports the detection liquid by activating the actuator device and performs filtration via the filter unit.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
