INFINITY-CTW

It was necessary to maintain for a long-term continuous observation every 1-2 weeks because an usual conductivity sensor is influenced sensitively from the dirt of the living thing adhesion etc.
The conductivity sensor of INFINITY-CTW adopts internal electrode sensor that the dirt of the outside doesn't influence measuring result at all.
In addition, because inside of pipe is cleaned with the piston type wiper automatically at each measurement, steady data can be acquired in 2-3 month even in no maintenance.
