Hey guys I just got my TDS (total disolved solids) meter and gives me readings in PPM, and I'm looking to convert it into EC (electrical conductivity). But when I google the conversions I get 3 different ppm conversions: Hanna, Eutech, and Truncheon.

I dont know which one my device is.

I put pic of the chart and of my meter if it helps.

Thanks

That TDS-3 is on the .5 scale (hanna)

Keep in mind, EC is actually what that your TDS-3 pen is reading. It's got a microchip in it to display ppm's based on the .5 (hanna) scale. The manufacturer decided to program it so it displays ppm's instead; and it's only an estimate of ppm's too.

How about these Xiaomi TDS meters? Are they Hannah as well? I have been looking for this info everywhere....
