OVERVIEW

The YSI IQ SensorNet 282 and 284 controllers are a modular system for a complete sensor network. This powerful, reliable system continuously measures your water quality parameters anywhere in a facility for process control. Immediate benefits include better network visibility and management, early detection of network failures, improved compliance with regulatory targets and cost savings (energy, pump/blower maintenance, labor).

The IQ SensorNet 282 and 284 controllers have an easy-to-read digital display and a USB interface and data logging capabilities for further analysis and troubleshooting. The 282 and 284 can connect to almost any communication protocol including MODBUS TCP, MODBUS RTU, PROFIBUS and PROFINET.

The 282 or 284 system is capable of measuring:

Dissolved oxygen (optical or electrochemical)
pH
ORP
Conductivity
Temperature
Orthophosphate
Turbidity – ultrasonic cleaning
TSS (total suspended solids) – ultrasonic cleaning
Ammonium
Nitrate
Nitrite – ultrasonic cleaning
NOx – ultrasonic cleaning
Potassium
Chloride*
COD / BOD – ultrasonic cleaning
TOC (total organic carbon) – ultrasonic cleaning
DOC (dissolved organic carbon share of TOC) – ultrasonic cleaning
SAC (spectral absorption coefficient) – ultrasonic cleaning
Salinity
Sludge Level
Specific conductance
UVT-254 – ultrasonic cleaning

*Chloride can be seen in the menu on the terminal but only the last value. There is no real-time monitoring and control function when used on the NitraLyt or VARiON sensor as compensation for nitrate.

The entire system accommodates 1 to 4 sensors for the above listed parameters in any combination. Add sensors at any time and at any location or exchange them with ease. Simply change sensors (parameters) and start getting data for the new parameter.

Only YSI can offer you:

3-year warranty
