HAPPY HARVEST pH 7.0 Calibration Fluid 250ml

Description

Happy Harvest pH 7.0 Calibration Fluid is a standardized buffer solution at exactly pH 7.0, used to calibrate pH meters for accuracy in hydroponic systems. Key Uses It ensures precise pH readings, vital for maintaining the 5.5-6.5 range where plants best absorb nutrients, preventing deficiencies from inaccurate measurements. Hydro growers often calibrate to 7.0 if targeting near-neutral pH, or pair it with 4.0 fluid for two-point calibration on advanced meters. Application Rinse your pH probe in distilled water, submerge in the fluid for 5-10 minutes, activate calibration mode, and adjust until the meter reads 7.0 exactly—recalibrate weekly or after 10-20 uses. ​ Safety Notes Non-hazardous but avoid contamination by not returning used fluid to the bottle; store sealed in a cool, dark place for longevity.
