The useful life of the probe is between 6 months to 1 year, dependant on use. Care must be taken to prevent breaking the probe. The glass bulb must always be submerged in liquid. For long-term storage, it should be kept in an appropriate storage solution.

Cleaning

Rinse with distilled water between uses to maintain the cleanliness of the probe.

For more thorough cleaning and/or reconditioning: Soak in a 4% HF for 5 seconds or HCl for 1-2 minutes. Then rinse with distilled water and store the probe in storage solution.

If the probe has been fouled:
