Flairfrom EC Calibration Solution 2.76 - 250mL Meters & Controllers here are the unmistakable indicatorsFor calibration of Conductivity (EC) meters in hydroponics Regular calibration of conductivity meters is essential to ensure accurate readings: Poorly maintained electrodes can upset the linearity (i. e. slope) of the readout values either side of the Conductivity Standards value. Thus it is essential to clean the electrode with Electrode Cleaner prior to calibrating. Conductivity meter electrodes normally become coated with impurities. The degree to
