Hi guys,
I recently bought an EC testrt off ebay, this one in fact: Hydroponics Water Digital EC Conductivity Tester Meter
I don't get how you convert the meter readings from µS/cm to EC.
When I measured just plain tap water I get a meter reading of 141µS/cm and with nutrient I get a reading of 249µS/cm
How do i do the conversion to EC, i'm looking for an EC of about 1.5?
Thanks for any help.
