WTW Portable colorimeter pHotoFlex® pH

With its unique multi-parameter function of photometry and electro-chemical pH measurement, pHotoFlex® pH shows its strength with more complex tasks in environmental management, such as water framework guidelines, during process monitoring with changing sites and for fish hatcheries by determining NH3 and CO2:

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 coloration. With a multitude of available test kits - from lot-certified cuvettes to economic powder reagents, it is suitable for monitoring by health offices via environmental monitoring all the way to service labs. A list of favorites for the most commonly used tests, sample ID numbers and more than 3,000 measurements per battery set facilitate field measurements.

The integrated pH function is a complete electro-chemical pH measurement of pH 0-16 with automatic buffer recognition (TEC/NIST) by using the comprehensive WTW selection of pH measuring chains. The temperature compensation automatically takes place in the admissible measuring ranges from -5 … 100 °C. The WTW MultiCal® routine allows the automatic calibration with up to 3 calibration points. For field use, there is, for instance, the maintenance-free SenTix® 41 is recommended, for precision measurements in the lab, the glass electrode SenTix® 81 is frequently used.

The optional PC software LSdata offers GLP-compliant data evaluation with data filter and allows the input of up to 100 user-defined programs, automatically calculate these as methods and save them to the pHotoFlex®. For the convenient use in the field, there is a case set available, including the pH probe SenTix® 41 as a mobile lab with work surface and storage compartment as well as a lot of accessories, such as pH standards, tripod, pipettes and replacement batteries. For lab use, the photometer can be used in conjunction with a LabStation (optional) with site-supplied power and fitted with an external barcode reader.
