Water/Wastewater 15 photoLab® – The New Generation


of WTW Spectrophotometers WTW’s photoLab®


photometers offer a unique combination of routine and research features:


Routine measurements are covered with a wide range of commercial tests and extended Analytical Quality Assurance (AQA) functionality.


Research users have a full range of applications including spectral scans, kinetics and multi-wavelength measurements to complete their analyses.


photoLab® 6100 VIS is designed for use in the VIS range


from 320 to 1100 nm and offers the best optical performance in its class. It is ideal for water analysis with commercial tests kits, and all kind of VIS measurements in routine labs or education.


6600 UV-VIS, with a wavelength range from 190 to 1100 nm is designed to cover all applications in the complete UV-VIS range. Direct methods e.g. SAC at 254 nm are already stored for immediate use. The photoLab®


photoLab® 6600 UV-VIS is an excellent choice


not only for water analysis and service labs but also for teaching and research. Both models feature: •Multiple AQA functions.


•More than 150 methods for commercial test kits, including bar-coded cuvette tests and reagent tests for trace analysis in drinking water.


•User-defined methods and profiles for scans and kinetics. •High accuracy by elimination of cuvette faults. •AutoCheck, comprehensive testing utility. •Automatic cuvette recognition without switching adapters •Two built-in USB interfaces and an RS 232 interface for easy data management.


WTW is the pioneer of integrated Analytical Quality Assurance and has expanded and optimised these functions in the new photoLab®


series – the quality you expect from WTW. photometers. Additional software for


administration and user recognition is included and can easily be activated when needed. The new photoLab®

data management with WTW's photoLab® Data Spectral


Data spectral is a helpful tool for convenient 6000 Series spectrophotometers.


This software package allows a safe handling of the original data taken with photoLab® processed:


meters 6100 VIS and 6600 UV-VIS. They can be exchanged, safely backed-up and post-


•GLP-compliant administration of data reading instrument ID and using the complete user administration as set in the photoLab®


•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. Reader Reply Card no 39 SenTix® F – a New pH Electrode for Mobile Measurements


In the lab, pH electrodes are mostly used at constant temperatures. This doesn’t apply for electrodes in the field measurement. They are frequently exposed to changing conditions of environment and samples which may lead to temperature effects from the reference system that can not be compensated for.


This is solved by the new SenTix® F pH electrode from WTW. It has a modern


iodine/iodide reference system that shows almost no temperature dependence. With a rugged plastic shaft it is ideal for field use under any conditions.


The SenTix® Reader Reply Card no 40 F is available as an IDS electrode for the new WTW MultiLine® multiparameter instruments too. Reader Reply Card no 41
