If a conductivity meter is calibrated with aqueous standards, can it be used to measure the conductivity of an organic-based solvent system?

Trying to figure out if the calibration solutions for a conductivity probe/meter must be of a similar nature to the system which will be measured. I can only find aqueous calibration solutions online, and the solvent systems that I need to monitor are ethanol and methanol based. If I use the aqueous calibration solutions, will my measurements in the organic systems be accurate?
