AD310  are compact EC meters featuring automatic
 EC calibration, HOLD function, low battery indication, temperature
measurement and compensation.

Both models are supplied complete with AD3005D/1 conductivity probe with built-in temperature sensor and 1 m cable, batteries (4 x 1.5V AA alkaline) and instruction manual.

The autoranging feature of the EC and TDS readings automatically sets the instrument to the scale with the highest resolution. Measurements are compensated for temperature effect automatically (ATC) or manually (MTC). The temperature compensation feature can also be disabled to measure actual conductivity or TDS. The temperature coefficient is user selectable. The instruments also feature a measurement stability indicator.

Auto-off after 8 minutes of non-use conserves energy and lengthens battery
lifespan.
