Consumables for pH and ORP Sensors
Solutions for setting, cleaning and storing your sensors. For great durability and clear measurement results.
Product description
3 Molar KCl Solutions
3-molar KCl solution is most suited to the storage of pH and ORP sensors (e.g. in sensor quills) and as an electrolyte for refillable sensors (e.g. PHEN, RHEN).

ORP Quality Buffer Solutions
Accuracy ± 5 mV. Their shelf life depends on how often they are used and how strong the carryover of chemicals is.
Buffer solutions should be replaced a max. of 3 months after first opening.
Please note: The ORP buffer solution 465 mV is classified an as irritant (GHS07).

pH Quality Buffer Solutions
Accuracy ±pH 0.02 (±0.05 at pH 10). The shelf life depends upon frequency of use and the amount of chemical drag-in.
Alkaline buffer solutions can react with CO2 if left open. This will affect their values, therefore close after use. Buffer solutions should be replaced a maximum of three months after opening. The solution contains a biocide to prevent bacteria forming.
