4 MODES TO CHOOSE FROM
Press the MODE button to switch
between the 4 display modes
shown below.
FOR BEST RESULTS
Positioning: When testing, hold the meter straight up without letting it touch the sides
or bottom of the container.
Rinse: If switching between low and high ppm water, always rinse the probe with clean
or distilled water between uses to avoid any buildup.
INSTRUCTIONS FOR USE
1. REMOVE
Remove the protective
cap and press the
ON/OFF button.
MODE 1
TDS ppm
MODE 2
EC μs/cm
MODE 3
Celsius
MODE 4
Fahrenheit
4. WAIT
Wait a couple of
seconds for the
readings to stabilize
and automatically lock.
2. IMMERSE
Immerse the meter into
the water/solution up to
the Upper Immersion Line.
Do not exceed this, as the
meter is not waterproof.
5. READ
Take the meter out of the
water to read the results.
AFTER USE
Press the ON/OFF button for
3 seconds to turn the meter off.
Rinse in clean water and shake off
any excess.
Gently wipe the probe and replace
the protective cap.

3. STIR
Lightly stir the meter to
remove any air bubbles.

MEASURING SALT LEVEL
TDS meters can be used for estimating salt levels (NaCl). You can
simply multiply the TDS reading by 0.9 to obtain a ppm salt level.
Note! A TDS meter isn’t designed for testing water hardness. You
can find purpose-made Health Metric Water Hardness Test Strips on
Amazon: bit.ly/TESTWHT
STORAGE AND MAINTENANCE
Store in a cool dry place away from direct sunlight. Always make sure
the probe is kept clean, and the protective cap is replaced after use.
Automatic Temperature
Compensation (ATC):
Equipped with ATC, this meter
is suitable for cold and warm
liquids.
Auto Shut-Off:
For extended battery
life, the meter will
turn itself off after 2
minutes of inactivity.
Auto-Lock:
This function locks
stabilized readings
automatically. If you
prefer to do this
manually, just press
the ON/OFF button
to lock the result.
HELPFUL FUNCTIONS

CALIBRATION INSTRUCTIONS
Your TDS meter is factory calibrated
(at 342 PPM), so you can use it straight
out of the box. However, if you wish to
re-calibrate it, use a NaCl-based TDS
calibration solution.
Note! The meter and probes must be dry
when placed into the calibration solution
to avoid contamination.
1. Turn on the meter and dip it into
the calibration solution. Stir for a few
seconds, then keep it still for 1 minute.
2. Press and hold the MODE button
until the reading on the screen flashes.
This indicates that the meter has
entered calibration mode.
3. Press the ON/OFF button to
increase the result value, or the
CLEAR button to decrease it.
4. Adjust the result value until it
matches the ppm of the calibration
solution. You might not be able to
get an exact match, but as close as
possible is OK.
5. After finishing the adjustment,
press and hold the MODE button
until the reading on the screen stops
flashing. This indicates that the meter
has exited calibration mode.
6. Rinse the meter with clean water.

Calibration Tips
● TDS meters measure EC and convert
it into TDS. Small fluctuations in EC
can cause small variations in TDS,
even in the same calibration solution
or water sample. Don’t worry, this is
normal.
● The calibration solution can be used
several times if care is taken not to
dilute or contaminate it.
● If during the calibration procedure
the meter becomes unresponsive,
remove and re-insert the battery. This
clears the meter and allows you to
complete the calibration process.
When to calibrate your meter?
● After prolonged usage, recalibration
may help to increase the meter’s
accuracy.
● TDS meters are more accurate
when calibrated at levels that are
close to the sample being tested. So,
if you’re measuring samples that are
around 1000 ppm, for example, it’s
recommended that you calibrate the
meter for that specific value.
