Single probe 2 point calibration solution sets

The single probe will require calibration. If you require calibration solutions please order here

The solutions come pre diluted in 2 parts, choose either 2-20ppm, 20-200ppm or 100-1000 ppm

The solution names:

S3mg 2 part (multi-ion complex solutions similar to high EC hydroponics solution)

SNPK 2 part (multi-ion complex solutions similar to low EC hydroponics solution contains Phosphate)

SWWAT 2 part (multi-ion complex solutions similar a waste water or bore water sample)
