WTW Portable Photometer pHotoFlex® Turb

WTW pHotoFlex® Turb - Total Capability
A portable multi-parameter LED filter photometer with full electrochemical pH function and integrated IR turbidity measurement acc. DIN / ISO, with about 200 methods and 100 user-defined methods, 1000 records, optional laboratory application and evaluation via LabStation, single unit including turbidity standardset, optional: battery and power plug, LabStation with battery and LSdata software, pH probes.

The pHotoFlex® Turb is analogous to the pHotoFlex® pH, but includes an infrared (IR) light source for nephelometric turbidity measurement (90°), according to the requirements of DIN 27027/ISO 7027. Its precision is comparable to laboratory instruments for turbidity measurement. Together with the AMCO Clear® standards highest precision for the sensitive testing of drinking water is given. The calibration with the supplied AMCO Clear® standards and measured data can be documented and output via RS232.

Additionally:

• Turbidity measurement according to DIN 27027/ ISO 7027
• 0-1100 NTU/FNU
• Calibration kit (0.02-10-1000 NTU)

pHotoFlex® pH
The portable photometer pHotoFlex® pH demonstrates its capability with complex tasks in environmental and process monitoring at a variety of sites.

• Integrated pH measurement
• Automatic temperature compensation
• NH₃ and CO₂

The integrated pH function allows measurements of pH 0...16 with automatic buffer recognition (TEC/NIST). Temperature compensation is automatic within the permitted range of - 5...100 °C (23...212 °F). WTW's MultiCal®-routine allows the automatic calibration with up to 3 calibration points. WTW offers a large selection of pH electrodes as optional accessories: For field use, the maintenance-free SenTix® 41 is recommended, whereas for precision measurements in the laboratory, the SenTix® 81 glass electrode could be used.
