• Overview

  Model pHotoFlex STD (colorimeter only) and Model pHotoFlex pH (colorimeter with pH electrode capability) feature:

  • Calibration adjustment for selected methods
  • Data storage; 100 data sets with pHotoFlex STD and 1,000 data sets with pHotoFlex pH
  • Large, easy to read backlit LCD display
  • IP-67 waterproof case; easy to hold or set on a benchtop (lab station also available)
  • Flexible, fixed adapter for various cell types features a flip design to accommodate a variety of heights and diameters; it is also attached to prevent it from being lost
  • ~138 parameters (pHotoFlex pH); 85 parameters (pHotoFlex STD) - reagents can be used on YSI colorimeters or any other brand
  • PC connectivity to manage data (optional LSdata software) and update firmware or methods; barcode compatibility
  • pHotoFlex pH offers a BNC connection in order to take pH measurements directly and to measure the pH dependent parameter NH3

  ​pHotoFlex pH/SET or STD/SET Includes the pHotoFlex pH or STD colorimeter with the above features but also comes in a convenient kit:

  • field case with field tray
  • vials
  • pH electrode (with pH/SET)
  • 2 each 10 mL and 2 mL syringe
  • empty cuvettes 16+28 mm
  • cleaning tissues
  • stand
  • 2 empty buffer bottles
  • beaker
  • screw driver
  • PC-software LSdata
  • and RS232 PC cable

  If you are interested in measuring chlorine or COD only, you might be interested in our single parameter colorimeters, YSI 900 Chlorine and YSI 910 COD.
