Hanna® pH 4.01 Calibration Fluid to calibrate your pH Meter
Individual sachets of 20ml each.
The pH meter should be calibrated for first time use and re-calibrated regularly, depending on how much it is used and how it is handled, stored and cleaned.
Always calibrate with both Calibration Fluids 4.01 and 7.01 for a correct setting of the pH range.
We include a separate user manual with guidelines specifically for use in the float industry.
Tip: Always rinse the pH meter after use and store with Storage Fluid at room temperature. Store all Calibration Fluids at room temperature.
