AD331 Professional Multi – Parameter Splash Proof pH – ORP – Temperature Portable Meter

Description

MODEL: AD331

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 instruments also features a measurement stability indicator, GLP capability and a user selectable ID code to uniquely identify the instrument.

AD331 supplied with:

  • User manual
  • 1.5V AA alkaline battery (4pcs)
AD76309 4 ring stainless steel conductivity / TDS probe with built – in temperature sensor AD70004P: pH 4.01 calibration solutions in 20mls sachets in box of 25 pcs.
