Accuracy of control and measuring devices deteriorates over time of operation.
The only viable way-out to get reliable measured values would be to perform regular checks and calibrations of measuring devices with buffer solutions.
Standard buffer solutions are intended to check and setup accuracy parameters of measuring devices within any pH meters to determine activity of hydrogen ions in various medium.
Usually, OverGrower pH sensor shall be calibrated at least once a month.
On average, one liter of the calibration solution is sufficient for 45 applications: 25 ml per calibration.
Storage terms and conditions, as well as solution proportions are provided on the bottle.
- Nominal 6.86 pH
- Volume: 1 L
- Calibration accuracy — up to two decimal places of a pH unit.
- Solutions for reference samples are prepared from standard second-grade dilutions, and provide for the device set-up to ensure correct correlation between a signal coming from an electrode and pH value of the operated liquid.
