- Model TPNA-500 - Automatic Total Nitrogen/Phosphorus Monitoring System



More than 10 years have passed since the 5th Water Use Regulation was enforced in 2001. From the perspective on preservation of ambient water quality, it has become a matter of course for companies to be compliant with regulations and observe corporate compliance. Total nitrogen and total phosphorus monitoring in the future has the potential to lead to proactive enhancement of corporate value, in addition to compliance with regulations. While we propose technological innovations and improvements and LCC*1 reductions, we will pursue the future where regulations are strictly observed and corporate value is improved through monitoring.

  • Adoption of stain resistant measurement system : While adopting a reduced reagent volume (1/10) realized by our conventional model, employing a new measurement method (meniscus measurement method) and enhanced automatic washing functions (optional) have been achieved, contributing to lengthening the maintenance cycle.
  • Reduction in power consumption by approximately 30%, and pure water and waste water to 1/2 : We have reduced the cost for electricity, use of pure water and waste water treatment (including labor) as well as environmental burden (as compared with our conventional product).
  • A variety of washing functions : sampling point backwash purge function, line washing function during reagent change, automatic sample line washing function*2
  • Ultraviolet oxidation decomposition method; Domestic market share of approximately 60%. No. 1 in the industry*3
  • Color touch panel; Improved visibility and operability.
  • A built-in load volume operation function
  • USB data output port
