Corrosionguard Water Ingress Alarm System Potential Transmitter for Cathodic Protection System

The main purpose of this device is to monitor the water ingress situation in the cargo hold. When water enters the cargo hold, the device will sound an alarm and flash a light to alert the duty personnel to take appropriate action.

The QYJP100 monitor is a cabin water level monitoring and alarm system for ships. Its technical and performance indicators comply with SOLAS Chapter XI/12 and 13 amendments, as well as CCS (2003 No. 004 Circular) regulations. The water level detector meets the performance requirements of MSC77. The sound and light alarm meets the requirements of IMO "1995 Alarm Devices and Displays Rules" and is considered one of the more advanced products domestically.
