Photometers, WTW®

photoLab® series

Precise thanks to the high-quality lens system and fast thanks to barcode test recognition with automatic cuvette detection system. These instruments require little maintenance thanks to their exceptional photometric stability and wear-free design.
Extensive on-board AQS/IQK guarantees reliable results during measurement and documentation. Values can be read off as concentration, extinction or transmission.
More than 200 programmed methods with all essential settings for test sets are available for downloading and updating at any time from the Internet. The methods include all common parameters for analysis of sewage and drinking water, also for sea water and for pisciculture and fish farming, for food and beverage industries. Users are thus provided with both a high-quality and economical solution for everything from routine measurements to laboratory analysis. All photometers feature date and time and come with an RS 232 interface. 2 years warranty.
