pH Electrode Storage and Maintenance
To ensure a quick response and free-flowing liquid junc-
tion, the sensing element and reference junction must not
be allowed to dry out. The following instructions apply to
refillable electrodes. For gel-filled electrodes, consult
instruction manual.
Routine Storage
Soak electrode in a pH Electrode Storage Solution
(MA9015). If a storage solution is unavailable, pH 4 buffer
or pH7.01 may be used. The fill hole should be covered
to prohibit evaporation of reference fill solution.
Maintenance
Cleaning your electrode between and after use will help
extend the life of your electrode and avoid the cost of early
replacement.
Routine Cleaning
Soak electrode in MA9016 cleaning solution for half an
hour, followed by soaking it in storage solution (MA9015)
for at least two hours.
Weekly Maintenance
Inspect electrodes for scratches, cracks, salt crystal
buildup, or membrane/junction deposits.
Rinse off any salt buildup with distilled water, and remove
any membrane/junction deposits as directed in cleaning
procedures below.
The reference chamber should be drained, flushed with
fresh filling solution, and refilled.
The primary nutrients essential to plant growth and quali-
ty are Nitrogen, Phosphorous and Potassium.
N is associated with plant growth above the ground, P is
responsible for flower and fruit production as well as
overall plant health. K promotes disease
resistance, water intake and strong
root growth.
This kit provides accurate and profes-
sional tests and includes 25 sachets of
Nitrogen (MT5009), Phosphorous
(MT5010) and Potassium (MT5002),
3 x 100 mL bottles of extraction solu-
tion and 5 plastic test tubes. All
results are compared to stan-
dards on laminated colour
charts.
