pH Sensor Specifications
Electrode Maintenance
1
Before measuring soil pH, wet your soil sample with distilled water and ensure that
the soil is free of particulates. Even though the sensor is robust, hard surfaces such
as stones and pebbles can still cause breakage.
2
Rinse the electrode with electrode storage solution after each measurement.
Care has to be taken not to damage the sensor’s glass electrode especially while
rinsing the sensor.
3
In aggressive chemicals, dirty or viscous solutions, and solutions with heavy metals
or proteins, take readings quickly and rinse electrode immediately afterward. For the
sensor, the remnants of the semi solid samples on the penetrating electrode can be
removed by rubbing it with some table salt and then rinsing. Mild detergent can be
used to wash the penetrating electrode clean.
4
If possible, keep a small piece of paper or sponge in the electrode cap - moistened
with clean water or electrode storage solution (NOT de-ionised water) - and close
the cap over the electrode.
1
With dry hands, grip the ribbed instrument collar with electrode facing you. Twist the collar
counter clockwise (see figure 6). Save the ribbed Testr collar and O-ring for later use.
2
Pull the old electrode module away from the instrument.
3
Align the four tabs on the new module so that they match the four slots on the
instrument (see figure 7).
4
Gently push the module onto the slots to sit it in position. Push the smaller O-ring
fully onto the new electrode module. Push the collar over the module and thread
it into place by firmly twisting clockwise.
Note: It is necessary that you recalibrate your sensor prior to measurement
after an electrode replacement.
Electrode Replacement
You can replace the electrode module at the fraction of the cost of a new instrument.
When the sensor fails to calibrate or gives fluctuating readings in calibration standards,
you need to change the electrode.
Applications
Water quality testing • pools • spas • aquariums • aquaculture • hydroponics
• ecology studies • water and wastewater treatment • boilers • steam generators
• car washes • sanitation plants • labs • food sectors and more!
Warranty
Your waterproof instrument is warranted to be free from manufacturing defects for
1 year and electrode module for 6 months. If repair, adjustment or replacement is
necessary and has not been the result of abuse or misuse within the time period
specified, please contact your local distributor for assistance.
Return of Items
Authorisation must be obtained from your distributor before returning items for
any reason. When applying for authorisation, please include information regarding
the reason the item(s) are to be returned.
Note: We reserve the right to make improvements in design, construction
and appearance of products without notice. Prices are subject to change
without notice.
Changing Batteries
1
Open battery compartment lid
(with attached lanyard loop).
2
Remove old batteries; replace
with fresh ones. Note polarity.
