Dry the sonde port and probe connector with compressed air and apply a very thin coat of O-ring lubricant
to all O-rings before re-installation.
6882 CHLORIDE, 6883 NITRATE AND 6884 AMMONIUM SENSORS
You should clean these probes whenever deposits or contaminants appear on the ion selective membranes
located on the tips of these sensor modules. If possible, the
module should be cleaned while installed in the sonde
bulkhead. Use clean water and a moist piece of lens
cleaning tissue to
gently
wipe the sensor membranes until no
more contaminants are removed. However, under some
conditions, it may be necessary to remove the module from
the sonde bulkhead for cleaning and/or storage. To remove
the module, follow the diagram at the side. Remove the
module with finger pressure only, if possible. However, it is
acceptable to use small pliers if necessary to loosen the
module for final removal by hand.
Be very careful not to
squeeze the module any more than is necessary for a firm
grip. Use slipjaw pliers to minimize the chance of
applying too much pressure on the module
. While the
module is removed from the sonde, be sure to dry the sonde port and probe connector with compressed air
and apply a very thin coat of lubricant to the O-ring before re-installation.
NOTE
: The ion selective membranes are fragile. Be certain to: (1) Use only
moist
, high quality lens
cleaning tissue for the cleaning procedure (not paper towels or other coarse materials); and (2) Stroke the
probe face very gently with the tissue during the procedure.
If you do not adhere to these instructions, you
can seriously damage the sensors.
OPTICAL PROBES–6026 AND 6136 TURBIDITY; 6025 CHLOROPHYLL;
6130 RHODAMINE WT
The 6026, 6136, 6025, and 6130 probes require only minimal maintenance. After each deployment, the
optical surface on the tip of the turbidity probe should be
inspected for fouling and cleaned if necessary by gently wiping
the probe face with moist lens cleaning paper. In addition, for
the 6025, 6026, 6136, and 6130 probes, we recommended
replacing the wiper periodically. The frequency of this
replacement depends on the quality of water under examination.
A replacement wiper is supplied with the probes, along with the
small hex driver required for its removal and reinstallation.
Follow the instructions supplied with the probe to ensure proper
installation of the new wiper assembly. Additional wipers are
available from YSI.
2.10.3 SONDE
STORAGE
Proper storage of the your Sonde between periods of usage will not only extend the life of the sensors, but
will also ensure that the unit will be ready to use as quickly as possible in your next application.
