HI98331 Soil Test™
GroLine Soil Test
Direct Soil EC and Temperature Meter
with Built-in Stainless Steel EC Probe
The GroLine Soil Test EC (conductivity) and
temperature tester offers many advanced
features for growers of all types. The Soil
Test offers automatic one-point calibration,
stability indicator, hold functions to freeze
readings on screen, lowbattery indicator, and
selectable automatic shut-off.
With
its
compact
size,
single-button
operation, and ease of calibration, Soil Test is
the optimal tool for EC measurements made
directly in soil.

GroLine Quick Cal, pH and EC Calibration,
Cleaning and Storage Solutions
With GroLine Quick Cal solution only one solution is needed to calibrate both pH and
conductivity. This dual-purpose calibration solution is used with compatible meters with the
Quick Cal mode or with pH and conductivity meters that calibrate to pH 6.86 and 5.00 mS/cm,
respectively.
See page 2.139
GroLine also includes pH

solutions
in 120 mL and 250 mL bottles.
Maintaining a clean pH electrode is vital for not only in getting an accurate pH measurement
but also ones that are drift free. Any coating to the sensitive glass bulb or clogging of the
junction will impede the electrical circuit resulting in erratic and misleading readings. GroLine
cleaning solution ensures the maximum performance from the pH electrode to provide
readings that you can depend on.
See page 2.143
All glass pH electrodes need to be stored properly to guarantee an accurate calibration and to
protect the pH electrode frompremature failure. A few drops of storage solutionwill maintain
the hydrated layer on the glass bulb and prevent the reference junction and electrolyte from
drying out. GroLine storage solutions are specifically formulated to accomplish the task and
maximize the life of the pH electrode.
