This is such a nice thing to market because you can laser focus on niches. However, the copy on this landing page reads like a technical specs sheet.

I suggest you take the three benefits you have below the headline (affordable, precise, easy to use) and rewrite the copy by expanding on the benefits. Also use the examples listed. Like, how is this a great buy for a home brewer?

Another niche: swimming pool owners. Although it’s only worth it if I can link it to an action eg add acid but that feels a bit dangerous for diy project! Maybe a sms to add he acid and how much is good enough

A peristaltic pump is cheaper than the PH probe.

It sounds like a great idea on paper, but pools arent something people get really into when compared to sonething like home brewing or aquariums.

You might be right. What I might buy for say $50 or so is something that tests my water and tells me what to do. It’s need to be ready to go, not make it myself. This saves booking time to get the water tested at a shop. I don’t want to test using a kit as I don’t trust myself to sue it properly.

FWIW, I purchased it for exactly this reason. My goal is to end up with a URL that I can hit on my LAN that tells me the PH of my pool.

I don't need perfect accuracy, and checking it manually isn't overly time-consuming. It IS tedious enough that I only check it about once a week though, and I'd prefer to be checking it more often. And bonus points for being able to automatically track it & easily graph it, too!

Great idea - on it.
