AD130 is a heavy-duty portable pH meter designed to provide laboratory results and accuracy even under harsh industrial conditions.

Main features include:
7 memorized buffers for pH calibration (pH 1.68, 4.01, 6.86, 7.01, 9.18, 10.01 and 12.45)
Messages on the LCD to make the calibration easy and accurate
pH readings with manual or automatic temperature compensation
pH calibration using pH buffers with 0.01 resolution
Temperature range from -20 to 120°C (-4 to 248°F) using AD7662 probe AD130 can also use ORP electrodes to measure mV, with a resolution up to 0.1 mV.
