Product Details

Portable colorimeter pHotoFlex® pH - WTW

Lab2Go - no matter if environmental monitoring, service labs or aquaculture
With its unique multi-parameter function of photometry and full electro-chemical pH- and ORP-measurement, pHotoFlex® pH shows its strength with more complex tasks in like environmental monitoring e.g. for water framework guidelines, process monitoring in changing sites and for fish hatcheries and aquaculture by determining NH3 and CO2:

• more than 180 programs for standard parameters
• Smart adapter for wide range of test kits, vias and measurement concentrations
• Versatile with special methods NH3, CO2, color
• Electro-chemical pH and ORP measurement with automatic temperature compensation (ATC)

The energy-efficient LED optics with 6 wavelengths and a captive adapter for versatile applications with 16 and 28 cuvettes allows the measurement of the smallest concentrations with more than 180 programs for standard parameters and color.
