Waterproof pH meter for liquids and solids

I do a lot of gardening and also grow house plants. I used to test my soil by sending samples to the lab. So a pH meter that allows me to measure the pH of the soil directly sounds appealing. Plants usually have an "ideal" pH range in which to grow, so it's worth testing and changing the soil pH if you want the best plant growth. For example, blueberries, dogwoods, azaleas, and rhododendrons love acidic soil. Okra, asparagus, dianthus, purple crocus, clematis, cinquefoil, and lilac love neutral

Pros
  • An absolute legend
Cons
  • High price

Pros
  • Satisfied
Cons

I have a couple of complaints - the…

Pros
  • Hands free
Cons
  • Very expensive
