General Hydroponics Meter Calibration Solutions

General Hydroponics? uses the highest-quality reference solutions, 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 our solutions are precisely calibrated and yield reliable readings each time they are used.

Uses:

General Hydroponics pH 7.0 Calibration Solution is easy to use! Just dip your electrode into a small amount of the buffer and adjust the meter to read 7.0. Do not reuse the solution. This standard reference solution is of the highest quality and allows growers to calibrate many popular meter brands with confidence (NaCl scale or the 442 scales). Each batch is carefully checked to ensure that it is precisely calibrated and yields reliable readings every time.
