The Extech PH300 pH/Temperature Kit detects pH, mV, and temperature on your bench or in the field. It includes automatic, one-button calibration of 4, 7, and 10 pH with a three-point calibration option for greater accuracy and automatic temperature adaptation. Memory can hold up to 200 readings with the series number, measured value, and temperature. The meter has a big, blue, backlit LCD display screen with an auto power off and deactivate mode to save battery life. The IP57 waterproof housing keeps it safe from moisture and the weather. Includes a pH/mV/temp electrode, a protective rubber holster, pH calibration solutions (4, 7, and 10 pH), two AA batteries, a durable carrying case, and a user manual..
