with White Light Source
- Ideal for regulatory monitoring, process control or field use
- Simple operation
- Easy calibration
- Auto-ranging
- Meets USEPA
The TB 250 WL allows easy turbidity measurement in either the field or in the laboratory. Using a "white ligth" source and 90° detection, the TB 250 WL meets the specifications for EPA turbidity measurement (EPA Standard 180.1). A power efficient micro-circuit design allows the instrument to yield 5000 tests on 4-AA alkaline batteries with an estimated 7-10 years bulb life. Integrated diagnostics confirm proper operation and accuracy. The instrument features an Auto-ranging feature that automatically selects the correct turbidity range for your sample.
