WTW ProfiLine pH 3110 Handheld Meter (pH/mV, DIN connector), 2AA110

The WTW ProfiLine pH 3110 is a robust and reliable entry-level handheld meter for all users who need to measure pH values quickly and easily in the field, in the laboratory or on the production floor. It is designed to focus on the essential functions of pH measurement and offers maximum durability.

Extremely robust and waterproof (IP 67)

The housing is fully waterproof and dustproof to IP 67. (Feature) For professional buyers working in the field (environmental measurement technology, water analysis, aquaculture) or in harsh production environments, this means maximum reliability. (Benefit) The meter can withstand rain, dirt and even a fall into water.

Simple and Reliable Operation

Unlike complex devices with data loggers, the pH 3110 is optimised purely for measurement. (Feature) It features a clear, high-contrast LCD display and an intuitive keypad. The 3-point automatic calibration (using WTW TEC or DIN buffers) is easy to carry out and ensures reliable results. (Benefit) It is the perfect instrument for routine applications where the measurement value is required immediately but no digital documentation is needed.

Flexible electrode connection (DIN)

This meter is deliberately fitted with a standard DIN connector (for pH/mV) and 4 mm banana sockets (for separate temperature probes). (Feature) This allows procurement specialists the flexibility to continue using existing standard analogue electrodes from various manufacturers (Benefit).
