The energy-efficient LED optics with 6 wavelengths and a smart adapter for a variety of applications with 16 and 28 mm cuvettes allows the measurement of the smallest concentration with more than 150 programs for standard parameters, special methods and coloration. There is a large selection of test sets of lot-certified cuvettes all the way to economic powder reagents available. 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. or 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 pHotoFlex®Turb also has an infrared light source (IR) for the nephelometric turbidity measurement (90°) according to DIN 27027 / ISO 7027. In combination with th e long-term stable AMCO Clear® standard, the highest possible precision is also warranted for the sensitive drinking water area.
