Hanna (HI7071) Electrolyte Solution, 3.5M KCl + AgCl 4 x 30 mL bottles
Hanna HI7071 Electrolyte Solution
3.5M KCl + AgCl refill solution for maintaining optimal electrode performance in refillable pH and ORP probes
Precision measurement depends on proper electrode maintenance
Maintains Electrode Junction
The 3.5M potassium chloride concentration with silver chloride ensures consistent ion flow through the reference junction, preventing measurement drift and electrode polarization.
Prevents Reference Drift
Silver chloride stabilizes the reference potential, eliminating voltage shifts that compromise accuracy in pH and ORP measurements over time.
Extends Electrode Life
Regular refilling keeps the internal element hydrated and the liquid junction flowing properly, preventing premature electrode failure from dehydration or contamination.
FDA Compliant Packaging
Bottles meet FDA requirements for use in food and beverage testing environments where regulatory compliance is mandatory.
Works with Hanna refillable electrodes
The HI7071 electrolyte solution is formulated for all Hanna Instruments refillable pH and ORP electrodes that specify 3.5M KCl + AgCl fill solution. Check your electrode's reference chamber before refilling. Not for use with gel-filled or double-junction electrodes that require different electrolyte concentrations. Each 30 mL bottle provides multiple refills depending on electrode chamber volume.
When to refill your electrodes
Visual Inspection
Check electrolyte level in refillable chamber. Should be at or above the fill line. Low electrolyte causes slow response and inaccurate readings.
Heavy Use Environments
Refill weekly if electrode is used daily or in high-temperature applications where evaporation accelerates. Top off to fill line with HI7071 solution.
Standard Laboratory Use
Check and refill monthly for typical bench testing. Replace all solution if contamination or crystallization is visible in chamber.
Reactivation Protocol
Always refill after extended storage. Old electrolyte loses ionic strength and silver chloride precipitates, compromising reference stability.
Measurement Accuracy
Proper electrolyte maintenance is non-negotiable for reliable pH and ORP data
Cost Effective
Four 30 mL bottles provide months of refills at a fraction of electrode replacement cost
Quality Assurance
FDA compliant formulation meets requirements for food, beverage, and pharmaceutical testing
