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 for the storage of pH and ORP sensors (e.g. in sensor quills) and as an electrolyte for refillable sensors (e.g. PHEN, RHEN). We only recommend using the KCl solution saturated with AgCl for the old design of refillable sensors with reference electrodes without a large AgCl reservoir.

ORP Quality Buffer Solutions
Accuracy to ±5 mV. Shelf life depends upon frequency of use and the strength of the chemicals in sample solutions.
Buffer solutions should be replaced a maximum of three months after opening.
Warning: The 465 mV ORP buffer solution is an irritant!

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.
