MLSS/SLUDGE ZONE METER SS-1Z

The micro-signal from the detector that is composed of near-infrared LED & photo-diode & Water Pressure detector operates to amprify to enable digitally display THE MLSS DENSITY & WATER DEPTH of SLUDGE ZONE, and in addition, to determine for the sludge interface with a buzzer sound. And it is free from influence by outer light disturbance, because of the near infrared pulse light rays-light generating part and light receiving part modulation.
