TriOS NICO plus UV Photometer

TriOS NICO plus is a UV photometer that combines nitrate and spectral absorption (SAC254) measurement in one optical sensor. Its xenon flash lamp optics and turbidity compensation work without reagents and without sampling or sample preparation, with a power consumption of up to 7 W. Mikron Proses (Üsküdar, Istanbul), TriOS’s solution partner in Turkey, provides application consulting on sensor selection, commissioning and calibration.

Nitrate and organic load in one sensor

NICO plus measures both nitrate nitrogen compounds and the organic load of the water by an optical method. One sensor reports the following parameters:

• Nitrate nitrogen (NO3-N) and nitrate (NO3).
• SAC254 and UVT254: optical attenuation and UV transmittance at 254 nm.
• Organic equivalents: COD (CODeq), BOD (BODeq), TOC (TOCeq) and DOC (DOCeq).
• Turbidity and suspended solids: turbidity (Turb) and TSS (TSSeq), with turbidity compensation.

Optical path options

With the 10 mm standard optical path, the ranges are 0-5 mg/L for NO3-N, 0-60 1/m for SAC254, 0-88 mg/L for COD, 0-29 mg/L for BOD and 0-35 mg/L for TOC. Optical path lengths of 0.3, 1, 2, 5, 10, 20 and 50 mm can be configured to match the process.

Construction, maintenance and integration

• Housing: stainless steel (1.4571 / 1.4404) or titanium (3.7035).
• Response time: T100 response time is 40 s, and the measuring interval is at least 20 s.
• Maintenance: nano-coated windows and a 24-month calibration interval; typical maintenance is at most 0.5 hours per month.
• Outputs: Ethernet TCP/IP and RS-485 (Modbus RTU) digital communication; the manufacturer lists TriBox3, TriBox mini and Modbus RTU as compatible systems. See the TriOS TriBox controllers.
