What do you use to measure your PH?

I'm growing organically outdoors in 40L fabric pots, but have not been PH adjusting my water. The plants look really healthy so far, but I'm worried the PH buffering the soil (freedom farms) provides will get out of whack eventually. I have a Hanna PH/EC pen, which I got probably 15 years ago. I stopped by their shop in Bellville yesterday to replace the PH electrode and get new calibration solutions and they quoted me R3555. :classic_ohmy:.

So what do you guys use to measure your water PH as I'm not spending that much? Also, I have been using tap water left overnight to leach out the chlorine, but I also have loads of rainwater in my jojo tank. Which would be a better source to use? I always seem to remember the CT water being close to 8 PH.

Thanks.
