BNC Connection – BNC is one of the most commonly used connector types in pH meters and electrodes. Compatible with any meter or electrode that uses BNC connectors.
Best electrode care for great results
Keep the electrode hydrated
Why – Drying out the electrode leads to drifting pH values, slow response times, and incorrect measurements.
Fix – “Revive” a dry electrode by submerging the bulb and junction in pH storage solution for at least one hour.
Rinse, do not wipe your electrode
Why – wiping the pH glass can produce a static charge which interferes with the pH reading of the electrode.
Fix – Simply rinse the electrode with distilled or deionised water (DI). Blot (do not rub) with a lint-free paper towel to remove excess water.
Store your electrode in storage solution
Why – Storing in deionised water (DI) causes ions to leach from the glass membrane and reference electrolyte resulting in a slow and sluggish response.
Fix – Store your electrode in storage solution.
Clean your electrode regularly
Why – Deposits can form on the electrode during use, coating the sensing glass. This can lead to erroneous calibrations and readings.
Fix – Clean the electrode using a specially formulated cleaning solution for pH electrodes – ideally one that’s developed for your application.
Calibrate often
Why – All pH electrodes need to be calibrated often for best accuracy.
Fix – The frequency of calibration depends on how accurate you want to be – daily calibration is ideal.
Pick the right electrode for your sample
Why – General purpose electrodes are functional for a wide variety of applications but not ideal for all samples.
Fix – Based on your sample you may require an electrode designed for food, high-low temp, non-aqueous, or other types of samples.
Open or loosen the fill hole cap
Why – A closed electrode fill hole may lead to slower stabilisation times.
Fix – Loosen or remove the fill hole cap. Remember to put it back when storing the electrode. (Not applicable for non-refillable electrodes).
Keep the electrolyte level full
Why – Electrolyte flows out from the reference junction over time. Low electrolyte levels may cause erratic readings. (not applicable for non-refillable electrodes).
Fix – Ensure that your electrode fill solution level is no less than one-half inch from the fill hole cap.
Properly submerge your electrode
Why – Both the pH sensing glass and reference junction need to be completely immersed in order to function properly.
Fix - Add enough sample to submerge both the junction and sensing glass.
Inspect your electrode
Why – over time, the sensing portion of the glass becomes less responsive and will eventually fail. Damage from use is also possible. This will cause erroneous readings.
Fix – Check your electrode for damage and perform a slope and offset calculation.
