Bluelab pH Probe Care Kit for Hydroponic Systems and Indoor Plant Growing – Includes Calibration Supplies, Storage Solution, and Brush – Compatible with Pen, Meter, Monitor, Controller, and Tools – Clear Review

This kit is a rip off, you only get two disposable bags of each, they don't even give you back lids for the storage jars that contain them. meaningless. overpriced

Came with everything in the picture, the price is a bit high given how much solution is in the kit compared to how many bottles of solution but well I wanted to know a brush to use for cleaning the texture of the brush so I can buy cheap ones for future use

The cleaning set basically consists of a soft toothbrush and a cleaning agent, which can be replaced with soap according to the instructions. It also comes with a pH calibration solution and a few other goodies, but not in large portions, so you'll probably…

I have been using pH meters for over 15 years. When I first started using it, I went to YouTube to find out how to calibrate it. I watched some videos and said "never touch the electrode" (glass bulb). Based on this instruction, when the pH tester started not reading for a long time, I replaced it. When I used the cheapness for less than $10, the exchange was not a problem. When I started using a much better gauge with interchangeable bottom ends, replacement parts cost a lot more than the…
