NOT OVERFILL. It is important to leave space for the salt bridge thread and a small amount of air. 6. Screw the new salt bridge into the cavity until finger tight. Now perform a 1/4 turn with a 9/16” socket wrench. The salt bridge edges should be flush with the front of the probe face. Page 8 P/R65... -
Page 9: Storage
Sensors should not be left in dry lines or empty tanks for extended periods. 2. Do not store the sensors in a dry or humid location. When storing, check the protective cap(s) regularly to make sure the cotton ball remains moist. Improper storage of sensors voids the warranty. Page 9 P/R65... -
