actual size.
The PHH-257-KIT is designed for field and laboratory
measurement of pH. Supplied as a complete kit, the
PHH-257-KIT is perfect for transporting to remote locations,
keeping the equipment organized and ready for future
measurements. Standard features include automatic buffer
recognition and calibration, diagnostic error code display to
indicate defective electrodes or incorrect buffer solution.
The meter has a very precise 0.1 mV resolution, ideal for ion
selective measurements. The PHH-257-KIT comes complete with
meter, epoxy-bodied general purpose pH electrode, temperature
probe, carrying case and user’s manual.
