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 or kept at 100% humidity. For long-term storage, it should be kept in an appropriate storage solution.

Cleaning

Immerse in 10% nitric acid or hydrochloric acid solution for two minutes, then wash with distilled water. Do not scrub the electrodes, nothing should ever come into contact with them. If the acid solution isn't working, try increasing the temperature and agitate the probe.
