Gaskets
The gauge has three gaskets that will need to be checked at least
once or twice a year. These gaskets will seal the gauge from the
environment, and, if not inspected, moisture or water can get
inside the gauge and cause damage.
♦ If there is an erratic count of moisture, a hair dryer can be
used to dry the inside of the gauge.
♦ If the gauge is going to be stored for a long time, place the
gauge in an air-conditioned room or blow dry the inside of
the gauge to eliminate the possibility of moisture
accumulation. Also, loosening or removing the scaler to
allow the gauge to “breathe” will reduce moisture
accumulation.
All the gaskets can be replaced without removing the
radioactive source.
To remove the scaler gasket, remove the scaler, remove the old
gasket, and put the new gasket in place.
To remove the cover gasket and the base seal gasket, remove
the four screws that hold the cover and base together and raise
the cover. Remove the old gaskets and replace with the new
ones.
