We recommend that you calibrate you pH meter regularly. This Calibration Solution is used to adjust your pH meter to 4.01. Easy to use, just dip your electrode into a small amount of the buffer and adjust the meter to read 4.01. Do not reuse solution. Suitable for all makes and models of pH pens and meters.

General Hydroponics® reference solutions are of the highest quality, allowing growers to calibrate many popular brands of pH, EC and TDS meters (NaCl scale or the 442 scale). General Hydroponics® technicians check each batch to ensure that these solutions are precisely calibrated and yield reliable readings every time they are used.

Tip: The ideal pH range for most hydroponic crops is between 5.5 and 6.5.
