Portable photometers, pHotoFlex®

Supplier: WTW
pHotoFlex®
Portable photometers suitable for a wide range of photometry, turbidity and pH applications in the areas of environmental monitoring, water treatment, wine and beverage industries and process control.

  • User guidance via display for easy operation without handbook
  • Integrated pH measurement with automatic temperature compensation (except STD model)
  • Battery operation with four AA batteries for approximately 3000 measurements

A LabStation, that upgrades either the pHotoFlex or pHotoFlex Turb instruments into a small laboratory instrument, comprises a rechargeable battery pack (RB Flex) and LSdata software package. Routine measurements can be set via bar code and carried out without zero adjusting and therefore input of user-defined methods through the PC is simplified.  For connection of the LabStation to a PC, an AK cable is required.

Certifications: Turbidity measurement with infrared light source according to DIN 27027/ISO 7027 for pHotoFlex® Turb.

Delivery information: The pHotoFlex® set includes the pHotoFlex portable photometer with pH in a field case and tray to hold instruments and accessories. The pHotoFlex® Turb set includes the pHotoFlex Turb portable photometer with integrated turbidity and pH functions in a field case with appropriate accessories.
