Waterproof Portable Meters for Temperature measurement

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.

• 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

AD331 is a waterproof portable meter that reads Conductivity in 5 ranges and temperature. The autoranging feature of the EC range automatically sets the instrument to the scale with the highest resolution.

Measurements are compensated for temperature effect automatically (ATC) or manually (MTC). It is also possible to disable the temperature compensation feature to measure the actual conductivity.

The temperature coefficient is user selectable. This instrument also features a measurement stability indicator, GLP capability, and a user selectable ID code to uniquely identify the instrument.

AD330 and AD332 are waterproof portable meters that read TDS and Conductivity in 5 ranges and temperature. The autoranging feature of the EC and TDS ranges automatically sets the instrument to the scale with the highest resolution. Measurements are compensated for temperature effect automatically (ATC) or manually (MTC). It is also possible to disable the temperature compensation feature to measure the actual conductivity.

The temperature coefficient is user selectable. These instruments also features a measurement stability indicator, GLP capability, and a user selectable ID code to uniquely identify the instrument. Moreover, AD332 includes PC interface and printing function. Connect the meter to an external serial printer with the following printer specifications:

• at least 16 characters / line

• baud rate 9600

• 9-pin RS232 input
