Our products get pretty wide use in the industry. The main parameters we make testers for include TDS/EC/PH/Temp/Brix. We manufacture handheld pen type, controllers, and monitors. Our US office is in LA, but like a couple others in here, when I’m not traveling I get to work from my home in Indiana. My territory goes from North Dakota down to Kansas straight east to the Atlantic so I get around quite a bit. If you use our products or want to see something we make in person let me know, I can always add a stop to my travels. I’ve never seen a big commercial grow op in person and would love to do that if someone ever wants to give a tour.
I’m mainly here to just learn, but I’m happy to share my knowledge too. As far as education goes one thing I can’t say enough is store your pH pens/probes in storage solution NOT RO water. I have had multi location retailers not know this one important detail and then their store use pH pens die after 60 days. A few drops of storage solution a month will keep your pH probe alive a lot longer and make it require much less calibration.
