Hoping someone can help explain this for me.
I have Apera PH60 and Apera EC20, I’ve used the ph reader for a while now and it’s great. I calibrate around every 4-6 weeks and often find it was correct anyway.
With the EC reader I’m a little confused, mainly with converting it to what my feed chart shows, which is EC should be 1.8
My understanding from the picture below is I need to devide my reading which is in us/cm by 700 to get an EC reading. I’ve checked the manual but can’t find where to confirm the conversion rate, as it seems some models use 500:1 and some use 700:1
For example after following the feed chart I get around 1200-1300 us/cm which decided by 700 gives me around 1.8.
The post below does not specifically mention the EC20 model, it’s just the same brand.
Any help will be appreciated.
