Well there ya go Offmymeds, you might get lucky too and get by with a cheap one after all. Although the Truncheion reads in all scales making things pretty simple.

Hi. I have an HM com-100 from Europe I’m still confused which mode to use when measuring EC when I’m trying to get the .8 in seedling stage up to 2 in flower range for the feed. Not sure if this even makes sense to you. The HM digital has 6 conversions. hs(h is upside down)! mS, ppm.7, ppm.5, ppt.7,ppt.5. Can you help or confuse me even more. Lol
