Turbidity Meter NTM-100

Turbidity Meter NTM-100 is a portable turbidity meter which determines the number of suspended particles in water accurately and measures the turbidity by the intensity of reflected light. This model adapts 2 to 5 points calibrations using the Formazin Standards and is complaint with ISO 7027 and meets the requirement of nephelometric measurement at 90 stray light. It is therefore suitable for water analysis, cell cultures, food and beverage industries and (health) administration surveillance.
