The TU5 Series brings lab-quality turbidity measurement to your process. Using patented 360° x 90° detection, the TU5300sc reads the scattered laser light around the entire circumference of the sample vial — dramatically reducing the effects of stray light and particle interference for confident measurement down to 0.002 NTU/FNU. Configure the instrument, calibration, and compliance options you need below.
The TU5300sc is an online low-range laser turbidimeter for drinking water, filtration, and membrane applications. Its 360° x 90° detection method captures more scattered light than traditional 90°-only nephelometers, delivering greater sensitivity and tighter agreement between lab and process instruments. Choose from four instrument heads, optional RFID and System Check, and EPA (NTU) or ISO (FNU) regulatory versions.
Not sure whether you need the flow sensor, automatic cleaning module, RFID, or System Check? Our water-quality specialists can help you match the exact TU5300sc configuration to your regulatory framework and application before you order.
This sets your measurement unit and approved method. Choose EPA for US drinking-water compliance (NTU, Hach Method 10258) or ISO for international reporting (FNU, ISO 7027-1).

Solutions to the most common TU5 Series issues. Work through symptom, likely cause and fix before requesting service — most measurement problems are resolved by vial care and calibration.
Likely cause: Scratched, fingerprinted or condensation-covered sample vial, or bubbles in the sample.
Fix: Wipe the vial with a lint-free cloth and silicone oil, cap and invert to remove bubbles, and let cold samples equilibrate to avoid condensation before measuring.
Likely cause: Instruments compared manually without a common reference, or calibration drift.
Fix: Use the RFID option to run a one-tap comparison between the TU5200 lab unit and the online TU5300sc/TU5400sc, and verify both against the same StablCal standard.
Likely cause: Expired or improperly handled StablCal standards, or a dirty vial.
Fix: Use in-date sealed StablCal vials, invert gently (do not shake), clean the vial exterior, and repeat the guided RFID calibration routine.
Likely cause: Optics or vial contamination detected by the on-board self-diagnostics.
Fix: Clean the measurement cell and vial, confirm the light shield is closed, and re-run System Check; if the warning persists, update firmware to V1.11 or later.
Likely cause: Outdated firmware or an incomplete LINK2SC/SC controller configuration.
Fix: Install the latest TU5200 software update, then re-check the LINK2SC setup using the connectivity user manual.
