This section describes the proper procedures for care, maintenance
and storage of the sensors. The goal is to maximize their lifetime and
minimize down-time associated with improper sensor usage.
GENERAL MAINTENANCE
GENERAL MAINTENANCE - GASKET AND O-RINGS
The instrument utilizes gasket and o-ring seals to prevent water from
entering the battery compartment and the sensor port. Following the
recommended procedures will help keep the instrument functioning
properly.
If the gasket, o-rings and sealing surfaces are not maintained properly,
it is possible that water can enter the battery compartment and/
or sensor port of the instrument. If water enters these areas, it can
damage the battery terminals or sensor port causing loss of battery
power, false readings and corrosion to the sensors, ports or battery
terminals. Therefore, when the battery compartment lid is removed,
the gasket that provides the seal should be carefully inspected for
17
Page 13
contamination (i.e. debris, grit, etc.) and cleaned with water and mild
detergent if necessary.
The same inspection should be made of the o-rings associated with
the pH or ORP sensor connector when replacing a sensor. The o-rings
should be free of dirt or debris before installing the sensor onto the
cable. If no dirt or damage to the o-rings is evident, then they should
be lightly greased with the o-ring grease provided without removing
them from their groove. However, if there is any indication of damage,
the sensor o-ring should be replaced with an identical o-ring.
To remove the sensor o-rings:
Use a small, flat-bladed screwdriver or similar blunt-tipped tool to
remove the o-ring from its groove near the sensor connector. Check
the o-ring and the groove for any excess grease or contamination. If
contamination is evident, clean the o-ring and nearby plastic parts with
lens cleaning tissue or equivalent lint-free cloth. Alcohol can be used
to clean the plastic parts, but use only water and mild detergent on the
o-ring itself. Also, inspect the o-rings for nicks and imperfections.
Using alcohol on o-rings may cause a loss of elasticity and may
i
promote cracking. Do not use a sharp object to remove the
o-rings. Damage to the o-ring or the groove may result.
connector inside the port. If any moisture is present, use compressed
air to completely dry the connector or let it air dry. If the connector
is corroded, contact YSI Technical Support or the YSI authorized
distributor where you purchased the instrument.
Remove sensors upside down (facing the ground) to help
i
prevent water from entering the port upon removal.
SENSOR MAINTENANCE
Typical working life for pH and ORP sensors is approximately
12-24 months depending on usage, storage and maintenance.
i
Proper storage and maintenance generally extends the sensor’s
working life.
SENSOR MAINTENANCE - TEMPERATURE
You must keep the temperature sensor free of build up. No additional
maintenance is required. A toothbrush can be used to scrub the
temperature sensor if needed.
SENSOR MAINTENANCE - pH AND ORP
To re-install the sensor o-rings:
Place a small amount of o-ring grease between your thumb and index
finger. (More grease is not better!) Draw the o-ring through the grease
while pressing the fingers together to place a very light covering of
grease on the o-ring. Place the o-ring into its groove ensuring it does
not twist or roll. Use the previously grease-coated finger to once again
lightly go over the surface of the o-ring.
Do not over-grease the o-rings. Excess grease may collect
particles that can compromise the seal. Excess grease can also
i
cause the waterproofing capabilities of the o-ring to diminish,
potentially causing leaks. If excess grease is present, remove it
using a lens cloth or lint-free cloth.
GENERAL MAINTENANCE - SENSOR PORT
It is important that the entire sensor connector end be dry when
installing, removing or replacing a sensor. This will prevent water
from entering the port. Once the sensor is removed, examine the
18
CAUTION: When using a cotton swab, be careful NOT to wedge
the swab between the guard and the glass sensor. If necessary,
remove cotton from the swab tip, so the cotton can reach all
i
parts of the sensor tip without stress. You can also use a pipe
cleaner for this operation if more convenient.
Cleaning is required whenever deposits or contaminants appear on
the glass or platinum sensor surfaces or when the sensor’s response
slows. The cleaning can be chemical and/or mechanical.
Removing the sensor from the cable may make cleaning easier. Initially,
use clean water and a soft clean cloth, lens cleaning tissue, or cotton
swab to remove all foreign material from the glass bulb or platinum
button. Then use a moistened cotton swab to carefully remove any
material that may be blocking the reference electrode junction of the
sensor.
If good pH or ORP response is not restored, perform the following
additional procedure:
19
Page 14
1. Soak the sensor for 10-15 minutes in clean water containing a
few drops of commercial dish washing liquid.
2. GENTLY clean the glass bulb and platinum button by rubbing
with a cotton swab soaked in the cleaning solution.
3. Rinse the sensor in clean water (not DI water), wipe with a cotton
swab saturated with clean water, and then rerinse with clean
water.
If good pH or ORP response is still not restored, perform the following
additional procedure:
1. Soak the sensor for 30-60 minutes in one molar (1 M) hydrochloric
acid (HCl). This reagent can be purchased from most lab supply
distributors. Be sure to follow the safety instructions included
with the acid.
2. Rinse the sensor in clean water, wipe with a cotton swab
saturated with clean water (not DI water), and then rerinse with
clean water. To be certain all traces of the acid are removed
from the sensor crevices, soak the sensor in clean water for
about an hour with occasional stirring.
CAUTION: Do NOT mix the acid from the previous step with the
chlorine bleach in the following step. Toxic gaseous products
can be formed from the reaction between acid and chlorine
i
bleach. Be certain to copiously rinse the sink and drain system
of acid after its disposal and before disposal of the chlorine
bleach.
Dry the port and sensor connector with compressed air and
apply a very thin coat of o-ring lubricant to all o-rings before
i
reinstallation.
If this procedure is unsuccessful, as indicated by improper sensor
performance, contact YSI Technical Support or the YSI authorized
dealer where you purchased the instrument.
SENSOR STORAGE
SHORT TERM STORAGE
The instrument is supplied with a grey storage sleeve that slides over
the probe guard. The sleeve is used for short-term storage (up to 4
weeks). Be sure to keep a small amount of moisture (clean tap water)
on the sponge in the sleeve during storage. The moistened sponge in
the sleeve provides a 100% water saturated air environment which is
ideal for short-term sensor storage.
LONG TERM STORAGE
The ISE sensor should be stored in solution. When storing for more
than 30 days, place the ISE sensor in the storage bottle was originally
included with the sensor. This can be filled with buffer 4 solution. If you
no longer have the storage bottle, simply place the sensor in a buffer
4 solution.
If biological contamination of the reference junction is suspected or if
good response is not restored by the above procedures, perform the
following additional cleaning step:
1. First, be sure all HCl acid from the previous cleaning step has
been rinsed from the probe, sink and drain!
2. Soak the sensor for approximately 1 hour in a 1:1 dilution of
commercially-available chlorine bleach.
3. Rinse the sensor with clean water (not DI water) and then soak
for at least 1 hour in clean water with occasional stirring to
remove residual bleach from the junction. (If possible, soak the
sensor for a period of time longer than 1 hour in order to be
certain all traces of chlorine bleach are removed.) Then rerinse
the sensor with clean water and retest.
