Corrosion-resistant environment water detection device

The utility model discloses a water detection device for a corrosion-resistant environment. The water detection device comprises a detection water tank, an auxiliary tank body fixed on the front side wall of the detection water tank, and a transversely arranged main pipeline, the water inlet and outlet end of the detection water tank is communicated with the inner cavity of the main pipeline through a pipe fitting; a row of water quality detection probes for detecting the water quality in the detection water tank are arranged on the upper surface of the detection water tank. According to the utility model, sewage to be detected in the main pipeline is introduced into the detection water tank, the water quality detection probes are arranged on the upper surface of the water tank, so that the effect of detecting and evaluating the water quality is realized, and the corrosion-resistant film layers are arranged on the probes of the water quality detection probes and are used for resisting the corrosion of the sew
