Turbidity Meter / Analyzer – TC Series / M100


isolvBuilt in auto cleaning wiper with hard-to-scratch sapphire glass makes maintenance easy with reliable & stable measurement in harsh conditions.

Suspended solid transmitter uses a method of 90°C scattered light. In the method, a light source of a Detector illuminates the surfaces of suspended matter floating in the water and the light is scattered by these surfaces is detected by a photo element installed at an angle of 90° from the light source. The suspended solid is determined by the amount of scattered light.


• Build-in wiping cleaning system certainly keeps lenses clean
• Check and clean the window surface once every month.
• “Easy to Clean” scratch-proof sapphire glass for the optical windows
• Compact size can fit into any installation site
• Monitoring of clarifier overflow weirs in waste water treatment plants
• Final outlet of effluent from dissolved air floatation plants
• Raw water inlet measurements in water treatment plants
• Surface water monitoring
• Solids loading in rivers and streams
• Product breakthrough on plate heat exchangers
