Laboratory Multimeter pH/OVP/EC/TDS/Temp AD8000

A microprocessor based benchtop meter that provides pH, redox potential (ORP), conductivity, total salinity and temperature readings. Relative mV readings are also provided.

The auto-ranging feature for conductivity (EC) and total salinity (TDS) measurements automatically sets the instrument to the highest resolution scale.

For pH measurements, automatic temperature compensation (ATC) is available when using the AD5006 temperature sensor. For conductivity measurements, automatic temperature compensation is available when using a probe with a built-in temperature sensor, or the manual temperature compensation (MTC) function can be used. The user can also disable temperature compensation and measure the actual conductivity. The temperature coefficient is user selectable.

The pH can be calibrated to 1, 2, or 3 points using 5 buffer solutions in memory (pH 4.01; 6.86; 7.01; 9.18; 10.01).

In addition, the instrument has a calibration alarm function, a GLP reporting function for viewing the last calibration data, and a HOLD function for capturing the first stable reading on the LCD display.
