Basic pH Meter is great for the home grower when wanting to get an accurate pH reading from your nutrient solution. pH Meters are vital to a successful hydroponic grow as the nutrients will only be available to your plants in certain pH ranges being 5.5-6.5. This Basic pH Meter is super easy to calibrate and accurate for a basic meter.
You will need Calibration Solution pH 6.86 to calibrate this meter before its first use and at least once a month thereafter to maintain its accuracy.
