A useful note for field work:

For taking along all necessary utensils, such as test kits and spray bottle with distilled water as well as a disposal container, you can also pick a tool box from any from any building center to perfectly suit your needs.

Please note:

As floating and moving particles are measured in turbidity, slight measurement deviations are possible. In order to achieve results that are as representative as possible, attention should be paid to the following:
samples should be measured immediately, as particles otherwise settle.
constant lamp operating temperature.
condensation on samples should be avoided.
the position of the standards should be marked to exclude the influence of glass inhomogenities.

pHotoFlex®: The Portable Photometers

The pHotoFlex® series offers the most robust optics, combining precision with low power consumption achieved through optical filters together with the LEDs. The instruments are equipped with 6 wavelengths. Additionally, the pH measuring and the optional turbidity measuring (IR range) are integrated, making these instruments the perfect partners for all measurements in the field: in a wastewater plant for wastewater and reference measurements, in drinking water analysis at a wellhead or in a cistern, and for monitoring bodies of water. They are versatile, low current and offer many extra features.

pHotoFlex® – Portable Photometer with pH

  • More than 160 methods available
  • Integrated pH measurement
  • Color measurements

The portable photometer pHotoFlex® demonstrates its capability with complex tasks in environmental and process monitoring at a variety of sites.
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 sensors 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. The electrodes are described in detail in the pH measuring chapter.

pHotoFlex® Turb – Total Capability

  • like pHotoFlex®, additionally:
  • Turbidity measurement according to DIN 27027/ ISO 7027
  • 0-1100 NTU/FNU
  • Calibration kit (0.02-10-1000 NTU)

The pHotoFlex® Turb is analogous to the pHotoFlex®, 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.
The calibration with the supplied AMCO Clear® standards and measured data can be documented and output via RS232.
The AMCO Clear® standards enable highest precision for the sensitive testing of drinking water.
