2 in 1 ST210 Plastic Refillable pH Electrode

This delicate measuring instrument requires proper care and maintenance to produce accurate and reliable results and to prolong useful life. Always keep the electrode moist when not in use for a period of time by using an electrode storage solution (3M KCl). DO NOT store the electrode in distilled or deionized water, as this will cause ions to leach out of the glass bulb and reference electrolyte, causing slow and sluggish response. Remove the electrode gently from the storage bottle and rinse it with distilled water before use. For long-term storage, always keep the electrode in the bottle filled with sufficient storage solution to cover the bulb. Replenish the bottle as needed.

Suitable for normal samples. Use with OHAUS pH meters with BNC input connector and Cinch temperature connector.
