WTW ProfiLine pH 3310 Set: 2 pocket pH metres (logger & USB), 2AA312

The WTW ProfiLine pH 3310 Set 2 is a professional, portable pH measurement system designed for precise field measurements and comprehensive data documentation in accordance with GLP/AQS standards. Unlike the basic 3110 model, the 3310 features an integrated data logger capable of storing up to 5,000 entries and a waterproof mini-USB interface. This enables the automated recording of measurement series (e.g. long-term monitoring of water bodies) and rapid transfer to a PC without the need for proprietary adapters.

Measurement technology and process reliability

The device offers 5-point calibration and the tried-and-tested CMC (Continuous Measurement Control) function. This displays on the backlit graphic display whether the current measured value is still within the calibrated range and issues a warning in the event of deviations. This increases the reliability of the measured values, particularly with changing sample matrices.

Electrode and Robustness

‘Set 2’ includes the low-maintenance SenTix ® 41 pH electrode. It features a robust plastic shaft, an integrated temperature sensor (NTC 30 kOhm) for automatic temperature compensation, and a gel electrolyte that eliminates the need for refilling. The meter itself is waterproof to IP 67 (including the USB socket!) and can withstand brief submersion, making it the ideal companion in harsh environments or sewage treatment works.
