A tungsten electrode modified with polyaniline was prepared as working electrode. Ag/AgCl redox system was used as reference electrode. The sensor showed a Nemst response in the pH range of 2～ 12 with a response time less than 1 min. The sensor has been successfully employed to determine pH in the crucian from both the live fish to the putrefied fish.
