Decent EC meter

So many testers out there. What's worth the money?

Good value

I've been growing for decades and have never owned one........sorry I can't help.

I've been happy with the Membrane Solutions EC meter, model BTDSO3.

Make sure whatever you purchase can be calibrated. I have another cheap ebay EC-PPM meter that cannot be calibrated. The model above can be calibrated, but I had to retrieve calibration instructions from somewhere else, they were not included in the basic instructions. I calibrated it and it's been working fine for years.

Here are calibration instructions.

Ive had my hanna groline ec meter (ec meter only) since like May of 22’.
