The next standard in the evolution of turbidity
Compliant with EPA approved Hach Method 10258 and perfect for membrane filtration applications, the TU5400sc employs a patented optical design that sees more of your sample than any other turbidimeter, delivering the best low level precision and sensitivity while minimizing variability between measurements. For the first time you will be able to remove uncertainty of which measurement to trust between your lab and process instruments, thanks to identical 360° x 90° Detection® Technology in any TU5 Series® turbidimeter.
The TU5400sc Ultra-High Precision Low Range Laser Turbidimeter dramatically reduces the time needed to get a turbidity measurement you can rely on. With a 10mL sample size, response time is over 15 times faster than an FT660. A stable laser light source eliminates the need for annual lamp replacements. The turbidimeter’s measurement surface area has been reduced by 98%, allowing you to save time cleaning. With a mounting pattern identical to the FT660, replacing your previous turbidimeter is fast and simple.
All of this, along with the ability to measure to 0.0002 NTU, gives you the next standard in the evolution of turbidity.
A flow meter is included with this turbidimeter that continuously measures flow through the instrument and displays the flow value on screen. Current flow can be output to SCADA via 4-20mA or digital communications.
Ensure that your turbidimeter is always functioning properly with this TU5’s System Check capability. With the ability to provide information on measurement status and vial cleanliness, you can have full confidence in your turbidity measurement.
RFID technology included with this turbidimeter delivers easy calibration and simple, paperless turbidity measurement comparisons between your process turbidimeter and the TU5200.
