INW - TempHion Instruction Manual
Appendix D: How to Store and Recondition
When storing your TempHion, care must be taken to properly protect the electrodes,
including the reference electrode. After storage, before use, the electrodes may
need reconditioning, depending on the electrode and the mode of storage. INW’s
recommendations follow. If you have further questions, please contact your INW
technical support representative.
Storage
Reference Electrode
• Best if stored in fi lling solution.
• Alternately, can be stored in KCl.
• If storing dry, be sure to empty and clean reservoir (see maintenance section
earlier in this manual).
pH bulb / ORP
• Best if stored in pH 4 or KCl.
• Can be stored dry, but may shorten life of bulb. In INW’s experience, the bulb
should last roughly two years if typically stored dry.
ISE
• Storing dry is best.
Reconditioning
Reference Electrode
• If stored dry or in KCl, refi ll per maintenance section earlier in this manual. Once
refi lled, let sit for 30 minutes before using.
• If stored in reference solution, no reconditioning is needed.
pH bulb / ORP
• If stored dry, soak in 1st buffer for 4 hours before calibrating. (Must be calibrated
before use.)
• If stored in KCl or pH 4, no reconditioning is needed.
ISE
• If stored dry, soak in 1st calibration solution for 30 minutes before calibrating.
(Must be calibrated before use.)
PREVENT BATTERY LEAKAGE!
Under some circumstances the internal batteries can leak, causing damage
to the sensor. To prevent leakage, the following is recommended. (Does not
apply to lithium batteries.)
•
Change the batteries at least every 18 months.
•
If the sensor will not be deployed for 3 months or more, remove the
batteries.
