Ammonia Nitrogen Meter HC-200NH
Overview
HC-200NH is an ammonia nitrogen(NH4-N) meter using ion electrode method which is designed for aeration control in wastewater treatment.
Features
- Replaceable chip without the need for tools

- Combination with new-type ultrasonic cleaner improves antifouling property (optional)
[Burst oscillation method]
Enables continuous cleaning without damaging sensor, and long term adhesion prevention of stain.

- Sensor deterioration diagnostic during measurement *1
Deterioration diagnostic function during continuous measurement. This function reduces the risk of sudden loss of measurement and provides more reliable measurement.
- Optical DO sensor connectable (optional)

- 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 *2
