Waterproof Portable ORP Meters

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 AD5006 probe AD130 can also use ORP electrodes to measure mV, with a resolution up to 0.1 mV.

 AD131 and AD132 are heavy-duty portable waterproof meters for pH, ORP (Oxidation Reduction Potential) and temperature measurements, 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

• Calibration time-out alarm

• Log-on-demand

• HOLD feature to freeze stable reading on the LCD

• GLP feature to view last calibration data for pH and relative mV

• PC interface (only for AD132)

• Connection to an external serial printer with the following specification (only for AD132): at least 16 characters/line, baud rate 9600 and RS232 input
