GENERAL DESCRIPTIONGENERAL DESCRIPTION
EC and TDS are meters specially designed to
meet the needs of hydroponic and greenhouses.
The housing has been completely sealed against vapors and
humidity. They also float so that they can be quickly
retrieved if accidentally dropped in the tank.
The HI 1220 rugged EC/TDS probe incorporates a fast
responding temperature sensor. This means that readings
are quickly compensated for the temperature effect and they
are accurate every time. The probe can be simply replaced
and the rubber sleeve protects the DIN connector against
humidity and spills. The probe measures 25 cm (10”) and
can even be used to mix the fertilizer solution.
• Ideal for hydroponics and greenhouses
• Waterproof housing floats for quick retrieval
• Automatic calibration
• Auto switch off for longer battery life
• Fertilizer mixer (long and rugged probe)

OPERATIONAL GUIDEOPERATIONAL GUIDE
EC/TDS PROBE CONNECTION & MAINTENANCE
In order to protect EC/TDS
against vapors and humidity, the DIN connector is shielded behind a waterproof sheath.
• Slide the protective sheath down. Connect the HI 1220
EC/TDS probe to the DIN connector and then slide the
protective sheath back up all the way up to the EC/TDS
casing. To ensure maximum protection,
make sure the connector is completely covered.
• If the meter remains for a long time on the shelf and is
not used, it is recommended to clean the internal
sensitive pins with alcohol. Immerse the tip of the probe
up to the air-vent hole in alcohol for a few minutes.
• After use, clean the probe with tap water, dry it and
put it away.
• For cleaning after prolonged use, immerse the probe in
HI 7061 Cleaning Solution for ½ hour.
TAKING MEASUREMENTS
• Turn the meter on.
• Immerse the tip 5 cm (2”)
of the EC or TDS probe in
the sample.
Note: In order to have better
accuracy, allow the reading to stabilize. Any initial
variation may be due to
temperature compensation
and the fact that the
probe is adjusting itself
to the new sample.
BATTERY REPLACEMENTBATTERY REPLACEMENT
When the batteries are weak, EC and TDS will
display the warning symbol “Eb”.
To replace the batteries, open the back panel with the help
of a screwdriver and replace both AA type batteries, paying
attention to their polarity.
Batteries should only be replaced in a non hazardous area
using alkaline batteries.
Note: Once the batteries have been replaced, turn the
meter OFF and then ON again. Wait for 30 seconds
to allow the meter to complete the selftest before
performing a new calibration.
CALIBRATIONCALIBRATION
For better accuracy, frequent calibration of the instrument is
recommended.
• Turn the meter on.
• Press and hold the ON/OFF button for approximately 3
seconds. The display will start blinking “1500 ppm” for
HI 981409 and “5.00 ms” for HI 981410 to confirm
that you have entered the calibration mode.
• For TDS immerse the probe in the
HI 70442P and for EC in the HI 70039P
calibration solution.
Stir gently and wait for approximately
20 seconds to auto-confirm the reading.
Note: the probe should be submerged
approximately 5 cm (2”) in the
solution.
• Once the display stops blinking, the EC
or TDS is calibrated and
ready to use.
The instrument should be recalibrated at least once a
month, after cleaning the probe or replacing the batteries.

Recommendations for Users
Before using this product, make sure that it is entirely suitable for the environment in
which it is used. Operation of this instruments in residential areas could cause unacceptable interference to radio and TV equipment.
The metal band at the end of the probe is sensitive to electrostatic discharges. Avoid touching
this metal band at all times.
During operation, ESD wrist straps should be worn to avoid possible damage to the probe by
electrostatic discharges.
Any variation introduced by the user to the supplied equipment may degrade the instrument’s
EMC performance.
To avoid electrical shock, do not use this instrument when voltage at the measurement surface
exceed 24 VAC or 60 VDC.
Use plastic beakers to minimize any EMC interferences.
To avoid damage or burn, do not perform any measurement in microwave ovens.
