KWS-201 Online Ammonia Sensor with RS-485 MODBUS Interface for 0-100mg/L Range in POM+316L Casing
The KWS-201 on-line ammonia sensor is an essential tool for aquaculture. It is specifically designed to accurately measure ammonia nitrogen concentration in aquaculture water. With its advanced sensing mechanism, it provides real-time and highly precise data. This enables aquaculture farmers to closely monitor water quality and promptly detect any abnormal ammonia levels. The sensor's durable construction allows it to function stably in the aquatic environment, resisting factors like humidity and water impurities. Its user-friendly interface makes it easy to operate and interpret results. By maintaining optimal ammonia nitrogen levels, it helps ensure the health and growth of aquatic organisms, thereby enhancing the productivity and success of aquaculture operations.
Feature- Digital sensor, RS-485 output, supports MODBUS;
- No reagents required, no pollution, more economical and environmentally friendly;
- Automatically compensate for pH and temperature in water;
- Ion electrode method, no electrolyte required, electrodes can be replaced separately, easy to maintain.
