The Lutron pH222 is one of a new series of pocket testers from Lutron, and it is a culmination of many years of experience in pH instrumentation. It uses standard AA batteries, and has in build data logger for up to 100 readings. Calibration is automated in standard buffer solutions at 4, 7 and 10 or other values. Temperature measurement is included on the multiple display and the reading is used for automatic temperature compensation.
