HC-200NH

Field-installation type ammonia nitrogen meter

Ammonia nitrogen concentration in the tank is measured in real time with an ion electrode method sensor.

Ideal for aeration control and management in biological reaction tanks. It is equipped with a function that can diagnose the sensor degradation state by measuring the membrane resistance. Additionally, the reliability of measured values has been improved through the ability to perform continuous measurements while diagnosing deterioration.

Manufacturing Company: HORIBA Advanced Techno Co., Ltd.

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.
