Water/Wastewater 31 IQ-LabLink: The Link Between Online and Laboratory World
Matrix adjustment via IQ–LabLink What is matrix adjustment?
Matrix adjustment or referencing of the nitrate and ammonium sensors means the best possible adaptation of these sensors to the specific waste water composition of the particular plant. The raw sensor measurement values are compared to the photometric values of water samples taken from close by.
These photometric values are then given back to the sensor to correct the online measurement. What is IQ–LabLink?
IQ–LabLink is a new procedure for automatic bidirectional exchange of online and photometry data as required for matrix adjustment. Any risk of confusion is thereby excluded.
How does the matrix adjustment via LabLink work? Step 1, IQ SENSOR NET terminal (online):
Creates a job file on a USB stick with the currently measured sensor values Step 2, photometer (laboratory)
Reads the job file, assists the user with measuring the required parameters and stores the photometric data back on the job file 3. IQ SENSOR NET terminal (online):
Reads the photometric data from the job file and adjusts the sensor values accordingly WTW, an ITT Analytics company.

Global Water, an ITT Analytics company, manufacturer and distributor of water and weather monitoring equipment introduces the WE550 and WE570 weather instruments for highly accurate wind speed and direction measurements.
The WE550 Wind Speed Sensors and WE570 Wind Direction Sensors are constructed of high-impact materials, ensuring their durability and ruggedness even in severe weather conditions. The sensors have low thresholds and respond accurately to subtle changes in wind speed and direction. Both instruments have
a 4-20 mA output signal and are attached to 25 ft of marine grade cable, with lengths up to 500 ft available upon request.
Applications include predicting and supporting weather forecasts, determining the safety of mechanical equipment like cranes and lifts, controlling and estimating the efficiency of wind farms, navigation and safe operation in the shipping industry, and wastewater and landfill odour control.

Data spectral is a helpful tool for 6000
Series spectrophotometers. This software package allows a safe handling of the original data taken with photoLab® 6100 VIS and 6600 UV-VIS. They can be exchanged, safely backed-up and post-processed:
•GLP-compliant administration of data reading instrument ID and using the complete user administration as set in the photoLab®
meters •Data transfer from photoLab® 6000 series to PC for post-
processing and graphical elaboration in the user environment, e.g. with LIMS or spreadsheet
•Export of scans into spectra software for a consistent display and evaluation of multiple spectra
•Matching several meters at a time with methods, profiles and software-updates.
•Data mangement of the IQ-LabLink job files: The data sets contain all raw values of the WTW Online System IQ SENSOR NET and the matching reference values from the spectrophotometers of the photoLab®
6000 Series. WTW, an ITT Analytics company. Reader Reply Card no 110
