For calibration of pH Meters at pH 4.0
pH Buffer 4.0 @ 25° C (77° F)
Based on international (APHA) standard formula
This Cyco calibration solution 4.0 is used to test the acidity range of ph meters, ph pens and ph combo meters. By checking the acid range we can ensure that our ph pens and meters will read our hydroponic nutrient solution correctly.
Always calibrate your ph meter, or combo meter to calibration solution 7.0 first and then check using 4.0 only calibrating to one of these buffer solutions won't ensure ph probe accuracy.
Please note: CYCO calibration fluids may not be compatible with meters which require more precise calibration than regular meters.
