Water analysis Digital probes for measuring conductivity FYD 741 LFE01 and FYD 741 LFP with ALMEMO® D7 plug Just one single probe for measuring conductivity from very low (10 µS/cm) up to very high levels (500 mS/cm) 4-contact graphite electrode with high linearity across the whole measuring range Integrated NTC sensor for temperature compensation of measured conductivity values Suitable for the latest ALMEMO® V7 devices, including professional measuring instrument ALMEMO® 202 and precision measuring instrument ALMEMO® 710. Technical data and functions 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.
