Product details:

Australian Scientific is the official calibration fluids used for the Apera Instruments water control tools, such as their PH60 and PC60 pocket pH testers.

pH buffers standardised at 25°C and colour coded for easy recognition.

These buffers are electrometrically checked against standard primary buffer solutions in accordance with NIST using traceable reagents. 

Very accurate calibration solutions you can trust. If you're growing plants in hydroponics it's good to calibrate your ph meter consistently so the readings of your hydroponic nutrient solution can be trusted.
