Mobile Colorimeters, WTW®

(1) Mobile colorimeters: the pHotoFlex® series

The photometers / colorimeters of this series convince by their sophisticated technology for use on site, comprising an optional LabStation for easy evaluation and execution of laboratory tasks. 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®STD
For all those who only need photometry functions: more than 150 methods.

pHotoflex®pH
Photometers / colorimeter with electrochemical pH and redox measurement. Additional methods for ammonia and carbon dioxide.

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