Field pH Meters

These user-friendly handheld field pH meters are optimized for use on-site and in the field, but are accurate enough for the lab. Both field pH meters meet IP66/67 standards - no worrying about using it in the rain and mud, or accidentally dropping it in the water. These field pH meters have incorporated a sealed silicone keypad which offers real button response, yet allows for easy cleaning. Among the field pH meter's great features are: simultaneous display of pH or mV with temperature, choice of automatic or manual temperature compensation, and multipoint calibration with automatic buffer recognition at eight buffer values. Big displays allow the field pH meters to be read even under bad lighting conditions. The included battery allows the field pH meters to operate continuously for up to 2500 hours.

The field pH meters are offered in two great models.
The pH 3110 field pH meter is a great value for a robust and waterproof battery-operated pH/mV meter. The 3110 field pH meter features an intuitive 6-key silicone keypad and a simplified calibration method with automatic buffer recognition and display for standard buffers. The field pH meter's AutoRead function ensures stable and reproducible results. Typical applications for the pH 3110 field pH meter include simple pH measurements or use in high schools and universities.

The pH 3210 field pH meter also includes a built-in datalogger, real-time clock, GLP-supporting functions, backlit display for calibration and can be switched between pH and mV reading modes. The field pH meter can be configured with the MultiCal® automatic calibration for buffer recognition, and automatic temperature compensation. The pH 3210 field pH meter has a continuous measurement control (CMC) function that alerts you when your meter is reading outside of the calibrated range. The field pH meter's large memory allows you to manually store 200 datasets.

Both field pH meter models ship complete with water proof pH electrode with ATC; 50 mL each of pH 4 and 7 buffers; storage solution; electrode stand; beaker; batteries; and hard carrying case.
