IQ SensorNet Order Guide
The industry requires a successful, ongoing track record — YSI offered
the first practical dissolved oxygen sensor in the early 1960s. It requires
an array of capabilities from lab to field — YSI is a leader in laboratory
BOD instrumentation and spot sampling instruments for aeration tank
and effluent sampling applications. It requires exceptional support and
service — YSI is renowned for its pre- through post-sale technical support.
And now more than ever, municipalities demand a partner with the
added ability to improve their operational efficiency by providing
innovative solutions for continuous process monitoring and control.
The YSI IQ SensorNet product line is the best solution for the
wastewater industry...from small to large facilities. The network-based
YSI IQ SensorNet system is all about ease, scalability, and performance...
whether to monitor influent, reduce energy use during the aeration
process, monitor effluent, or control any part of the process such as
biological nutrient removal, phosphorus removal or returned
activated sludge lines.
YSI is excited to bring you our IQ SensorNet catalog. It’s a huge
step forward in continuous process monitoring and control. With
Your Brains and Our IQ, there’s nothing we can’t solve together.

(total and soluble)
IQ SensorNet UV and UV/VIS sensors are optical-based, reagentless
spectrophotometers built into rugged, corrosion-resistant probes that are
designed to measure accurately in harsh applications. Single and broad
spectrum options available. The spectral sensors scan 256 wavelengths per
measurement for increased accuracy and single wavelength sensors with
turbidity compensation are available for NOx and UVT-254 (SAC) measurements. All UV/ UV-VIS sensors utilize UltraClean™ ultrasonic technology to
prevent fouling and lower maintenance requirements.
All sensors:
• Ultrasonic cleaning with UltraClean™ technology prevents fouling and lowers maintenance requirements
• Built-in airholes for added air cleaning in high fouling applications
• No reagents required means reduced operational costs and less impact on the environment
• Durable, long-lasting materials: Titanium and PEEK will hold up in the toughest conditions
• 2-year warranty
• IP68
• Detection of organic loads immediately without reagents
Spectral Sensors (NitraVis, CarboVis, NiCaVis, NitraVis NI, NiCaVis NI, TSS):
• UV and UV/VIS sensors with 256 wavelength scan
• Scanning 256 wavelengths results in more accurate measurements and better
compensation for interferences
• User calibration possible for improved accuracy
• Factory calibrated per location in the process (influent, aeration, effluent)
• Ability to differentiate between Nitrate and Nitrite concentrations (on NI sensors only)
• Display up to five parameters depending on the application
• Calculated parameters: COD, TOC, BOD, Nitrate, Nitrite, TSS (depending on sensor)
Single Wavelength (UVT-254, NOx):
• Turbidity compensation
• Regulate and control UV disinfection with UVT-254
• Correlated parameters: COD, TOC, BOD, DOC from UVT-254 (SAC) measurement

provides continuous data to help improve operational efficiency, lower
operational costs as well as verification of phosphate elimination in order
to meet permit requirements.
• Reliable sample delivery system – sample pump is housed in analyzer
• Low reagent consumption – solutions exchanged every 4 – 8 months, reducing operational costs
• Automatic or manual calibration (user-selectable)
• Automatic or manual cleaning (user-selectable)
• Proven Vanadomolybdate (yellow) method of detection

The modular YSI IQ SensorNet water quality monitoring and control system is a complete
sensor network for a variety of application needs. This powerful system lets you easily add
more modules or sensors at any time while continuously measuring water quality anywhere
in your facility for the ultimate process control. In addition, you receive the exclusive benefits
below, as provided only by YSI. Sheer genius.
• UltraClean™ ultrasonic cleaning integrated into
turbidity, TSS, UV and UV-VIS sensors
• One cable for power and communication —
send measurement data back to control room via
IQ SensorNet cable. No need for 4 - 20 mA cable, extra
power drops and conduit runs.
• Display terminal connects to any module or network
• 3-year warranty, terminals and displays
• 2-year warranty, sensors
• Terminals, modules, and sensors can be placed
anywhere in the network
• Measure up to 20 parameters per network
• Network scales easily without new hardware
or engineering
• Smart technology recognizes and displays sensors
• Network outputs analog and digital signals
• Detachable sensors that use a universal sensor cable
Want one? Win it.
• USB electronic key function ‘locks’ and saves system
settings from accidental changes
• No calibration required on most sensors; automatic
drift compensation
• Measures DO, conductivity, temperature, pH,
ORP (Redox), nitrate, nitrite, NOx, soluble and total
for COD and SAC, UVT-254, orthophosphate, sludge
level, ammonium, potassium, turbidity, TSS, BOD,
DOC, TOC, chloride
• Optical DO sensor is immune to bubble interference
with unique angled design
• Back-up controller function with 2 display terminals
or 1 display and 1 MC2 module

Order Guide
Building a system is easy. Just choose an IQ SensorNet controller, select which modules you’ll need, determine
your distances for cabling, and select your parameters. And don’t forget your accessories. Let’s get started.
First, ask yourself this:
1) Which location are you monitoring?
(influent, biological tank, RAS line, effluent, etc..,)?
2) Which parameters do you need to monitor? Select sensors.
3) What type of outputs are required and how many
of each signal type? Select modules.
4) Which controller do you need?
(based on the number of parameters, outputs
and relays needed) Select controller.
5) What is the distance between modules? Select cable length.
6) How will the sensors and modules be mounted?
Select mounting.
Second, select your system:
