Short-term Storage:
When in regular field use, the sensor should remain installed on the sonde in an
environment of water-saturated air such as a storage sleeve with a wet sponge.
Long-term Storage:
Users should remove the sensors from the sonde and place them in their dry
storage bottle (installed on the sensor during shipping) to protect the sensor tip.
NOTICE:
Do not store the ISE sensors in any water or standard solution.
Rehydrate the Reference Junction
After an ISE sensor has been allowed to dry, soak the sensor for several hours
(preferably overnight) in the sensor’s high-calibration solution.
Sensor Module
Ammonium, chloride and nitrate sensors feature user-replaceable sensor modules. These modules contain a reference solution that
depletes over time. The warranty period for ISE modules is 6 months:
• Replacement Nitrate Module [SKU: 626965] =
6
months
• Replacement Ammonium Module [SKU: 626966] =
6
months
• Replacement Chloride Module [SKU: 626967] =
6
months
Depending on usage and storage practices, the module may last longer than its warranty period. When it is time, perform a sensor
module replacement in a clean, dry laboratory environment.
