TB 250 WL
- Ideal for regulatory monitoring, process control or field use
- Simple operation
- Easy calibration
- Auto-Ranging
Thank you for your interest in the TB250 turbidimeter. This instrument is discontinued at this time as we have developed a technologically advanced, portable turbidimeter, the TB350, that will be available in the next few weeks. Please click on the TB350 button below to receive more information.
The TB350 turbidimeter delivers the most reliable measurements for low range to high range samples, without sacrificing accuracy. It is ideal for field applications such as distribution monitoring, environmental samples or customers that test a wide range of samples.
We will continue to support accessories and standards affiliated with the TB250 turbidimeters.
Part Number 194200
Applications
- Drinking Water Treatment
- Pool Water Control
- Waste Water Treatment
Product information
The TB 250 WL allows easy turbidity measurement in either the field or in the laboratory. Using a „white light“ 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 batte-
ries with an estimated 7-10 year 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. Calibration is simple with the included calibration standards. The instrument comes with all required items for testing including the TB 250 WL Turbidimeter, sample cuvettes, batteries, calibration set, operators manual and carrying case.
