Digital Turbidity Meter – 335, 331 & 341
Features
- Reliable & Accurate Results
- Measurements upto 1000 NTU
- 3½ Digit 7-Segment LED Display
- Sewage and Drinking Water Testing
Clarity of water is extremely important in products destined for human consumption. Suspension free water is also considered necessary for industries manufacturing beverage, food products etc. Similarly, minimum limits of turbidity are required to be observed in drinking water & sewage disposals.
Ei’s Digital Turbidity Meter and Nephelometer are ideal instruments for measurement of suspensions. They consist of a light source focused on a test tube containing the sample solution under test. The light, reflected at right angle to the focused light by the suspension in the solution, is detected by the photo electric detector, amplified and displayed on a 3½ digit LED display.
