Extremely small and perfect for either hands-on or hands-free measurements, Extech's PH220 is a great tool for measuring pH, mV and temperature in various different applications.
This pH meter can measure pH from 0 to 14pH, mV from -999 to 999mV and temperature from 32 to 212°F (0 to 99.9°C). The meter relays information about two measurements at once and is capable of displaying a pH/mV reading and the detected temperature reading at the same time. Up to 25 of these records can also be stored directly on the devices' internal memory for quick and easy reference during testing procedures.
The PH220 is actually available in two kits: the PH220-C and PH220-S. This version of the product comes with a ATC pH Polycarbonate Electrode with 39" 1m cable, while the PH220-S comes with an electrode that clips directly into the device. The 1m cable included with this kit means it is much easier to carry out measurements from a distance and - by use of the devices' magnetic back - it is even possible to mount the meter on a metallic surface then use the probe in difficult applications.
*Please note that Extech pH meters must be kept moist using solution at a pH of 4 or they will dry out and not work.
