SenseCAP RS485 NH3 Sensor

The SenseCAP RS485 NH3 sensor is an industrial-grade sensor based on electrochemical technology, specifically designed for monitoring ammonia concentrations in challenging environments. The sensor is robust and reliable, making it ideal for applications in agriculture, industry, and environmental monitoring. Thanks to the MODBUS-RTU RS485 interface, the sensor can be easily integrated into existing systems and provides precise measurements for ammonia, temperature, and humidity. The IP65 protection class ensures protection against dust and water splashes, allowing use even under adverse conditions. The sensor installation is straightforward, and it can be calibrated both at the factory and by the user to ensure long-term accurate measurements. Another advantage of the sensor is its rapid response time and high resistance to environmental interference.
