light weight. Ideal for soft
drink vendors, etc., where
only limited space is available.
For low specific liquids. Used for sewage,
sea water, etc., having a low specific resistance. In sewage use, electrode holders
must be installed 10 to 20 cm apart from
one another. For acids, alkalis and sea water, electrode holders may be as much as
1 meter apart to operate properly.

Life expectancy Electrical: 100,000 operations min.
Note: 1. The relay in the 61F-GP-N8H de-energizes when there is water present across the electrodes, whereas the relay in the 61F-GP-N8HY
energizes when there is water present across the electrodes.
2. The length when using completely-insulated, 600-V, 3-conductor (0.75 mm
as the cable diameter or number of conductors becomes larger.
3. The insulation resistance and dielectric strength indicate values between power terminals and electrode terminals, between power ter-
minals and contact terminals, and between electrode terminals and contact terminals.
4. Possible to use with 10 kΩ or less, however, this may cause reset failure.
