Technical Features

The digital conductivity probe provides this high level of precision irrespective of any extension cables used and of any processing in the ALMEMO® V7 display device / data logger. Overall accuracy is determined exclusively by the conductivity electrode and the ALMEMO® D7 plug. All parameters for the sensor can be programmed end-to-end via the programming menu on the ALMEMO® V7 measuring instrument. The desired measuring range can be selected and temperature compensation can be activated or deactivated.
The temperature coefficient of the solution to be measured, if known, can also be programmed. The probe is delivered already adjusted and ready-to-use. The electrode‘s measured cell constant can also be entered, if so required, and / or the probe can be adjusted using a reference solution.
