HC-200NH
Field-installation Type Ammonia Nitrogen Meter(Four-Wire Transmission)
HC-200NH is an ammonia nitrogen(NH4-N) meter using ion electrode method which is designed for aeration control in wastewater treatment.
Segment: Process And Environmental
Division: Process Water
Manufacturing Company: HORIBA Advanced Techno Co., Ltd.
Intelligence
■ Sensor deterioration diagnostic during measurement *2
■ Optical DO sensor connectable (optional)
■ Sample adjustment function
■ Automatic potassium ion concentration compensation
Self diagnostic funcfion
Deterioration diagnostic function during continuous measurement. This function reduces the risk of sudden loss of measurement and provides more reliable measurement.
Dual channel transmitter
Easy maintenance
■ Replaceable chip without the need for tools
■ Combination with new-type ultrasonic cleaner improves antifouling property (optional)
■ Flat sensor surface (prevents bubble and stain accumulation) *2
■ No measurement reagent necessary
Replaceable chip without the need for tools
Unique Ultrasonic Cleaner (UH-16A series)
Enables continuous cleaning without damaging sensor, and long term adhesion prevention of stain.
Tough
■ The ion sensor enables long term stable measurement
■ New ion chip internal solution enables stable measurement (Japan patent No. 5144829)
■ New structure of reference chip achieves stability measurement *1
Long term stable measurement
Data from joint research with Bureau of Sewerage Tokyo Metropolitan Government
Evaluation Term: 6 months, Application: Aeration tank in Tokyo, Optional: Ultrasonic cleaner
Maintenance: Once a month (Wash sensor with water and sample adjustment),
Result: Stable measurement for 6 months without sensor replacement
*1: patent applied
*2: patent applied with Bureau of Sewerage Tokyo Metropolitan Government.
