Oxygen Sensors
APPROVED OXYGEN SENSORS
The EXPLORER is only approved to use Hollis EXPLORER Oxygen Sen-
sors. Hollis EXPLORER Oxygen Sensors have temperature ranges as
detailed below.
Operating temperature range: 0 – 40
°C
Storage temperature: -20 to +50
°C
Recommended storage temperature: +5 to +15
°C
OXYGEN SENSOR CARE
WARNING: For the sensor life prediction alarms to operate
correctly the oxygen sensors, if removed, MUST be replaced in
the same position.
WARNING: In the event of a faulty sensor, all three sensors
should be replaced together as it cannot be guaranteed that the
scenario that made the first sensor fail has not affected all the
sensors.
WARNING: Number each individual sensor before removal so
they can be replaced in the same position.
Basic care includes:
•
NEVER store sensors in any gas other than air.
•
NEVER subject sensors to high temperatures i.e. (Car trunks).
•
NEVER freeze sensors (left in cars overnight).
•
NEVER subject sensors to physical shocks.
•
NEVER subject sensors to vacuum.
•
NEVER submerge sensors in liquids.
•
Never attempt to open a sensor housing.
• Sensors deteriorate very slowly and near the end of their useful life may
show a reading drift soon after calibration.
• always change all 3 sensors together and after a maximum of 12 months
from first usage.
• Water and corrosion on the sensor jack plug may give false Oxygen
readings. Seawater may dry leaving a deposit on the jack connectors and
the sensor membrane. Always leave the sensor jack locking ring finger
tight on the sensor socket. If you suspect corrosion, remove the sensor
from the sensor module and clean the jack plug with a cloth and contact
cleaner.
