HC-200NH

現場安裝式氨氮計

利用離子電極法感測器即時測量罐內氨氮濃度。

非常適合生物反應池中的曝氣控制和管理。具有透過測量膜電阻來診斷感測器劣化狀態的功能。此外，透過在診斷惡化的同時執行連續測量的能力，測量值的可靠性得到了提高。

Prevention of contamination for increased longevity
The protective film improves sensor durability. Combined with an ultrasonic cleaner, antifouling properties are improved.

Improved long-term stability
HORIBA's proprietary technology ensures stable measurements.

Easy maintenance
Replaceable chip without the need for tools. No need to call manufacturer maintenance.

Reduced risk of sudden operational shutdowns
The self-diagnostic function of the sensor enables the immediate detection of anomalies.

Ensuring accurate measurement values
Easy calibration to match manual analysis values.

Simultaneous measurement of dissolved oxygen (DO)
The converter can be connected, not only to the ammonia nitrogen sensor, but also to an optical DO sensor.
