Photometers, WTW

Photo-Lab® 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. 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.

(4) pHotoFlex, mobile photometer with pH

pHotoFlex

The pHotoFlex handheld photometer features sophisticated technology for field use, with an optional LabStation for simple evaluation and operation in the laboratory. Handy and well arranged, it can also be used for pH determination. A large illuminated graphic display guides the user through all functions. A laboratory station with battery and charging function is available as an accessory for the the basic battery-operated model (4 AA batteries). Routine data measurement and evaluation can then be performed even more conveniently with an external scanner and evaulation software.

 

pHotoFlex Turb

Same as pHotoFlex, plus turbidity measurement from 0 to 1100 NTU / FNU.
