Abstract
An automatic ammonia hydroxide deployment system comprises an ammonia hydroxide deployment device and an automatic ammonia hydroxide deployment controlling device. The ammonia hydroxide deployment device includes a chamber for storing ammonia hydroxide, an ammonia pipe and a water pipe. The automatic ammonia hydroxide deployment controlling device includes an electrical conductivity meter, a liquid level sensor and an operating controller. The electrical conductivity meter is for detecting an electrical conductivity of the ammonia hydroxide in the chamber. The operating controller is configured to obtain an ammonia concentration of the ammonia hydroxide according to the electrical conductivity of the ammonia hydroxide. The operating controller adjusts ammonia gas flowing into the chamber according to whether the ammonia concentration is less than a predetermined threshold or not, and adjusts water flowing into the chamber according to whether the liquid level is lower than a predetermined lower threshold or not.
