Operating Manual
EcoTestr CTS1 Pocket Tester
•The batteries have been pre-installed. Please pull out the
insulating paper before first-time use. When replacing batteries,
the positive side (+) of every single battery must face up. Please
check the detail in "Battery Installation" section.
• Before shipment, the factory adds in some water droplets to the
tester's cap. This ensures that the probe keeps its sensitivity. This
practice of adding several drops of water into the cap to keep
sensor activation is highly recommended when storing the tester.
Calibration
1. The tester only needs to be calibrated for conductivity, then
press to switch to Conductivity → TDS→ Salinity.
2. Press and switch to conductivity mode, rinse the probe in
distilled water and shake off excess water.
3. Long press to enter calibration mode; short press to exit.
4. Dip the probe into 1413 μS/cm calibration solution. Stir gently,
leave it to stand. Wait for the measurement stability icon () to
appear and stay on the display, then short press to complete
the 1st calibration. Tester returns to measurement mode, and
calibration icon “M” appears on the bottom left side of display.
5. Rinse probe in distilled water and shake off excess water. Repeat
#3 and #4 to complete 2nd calibration in 12.88 ms/cm calibration
solution. Tester returns to measurement mode, and calibration
icon “M” and “H” will appear on the bottom left side of display.
1. Short press to turn on the tester, short press to switch to
the desired measurement mode (Conductivity, TDS or salinity).
Rinse probe in distilled water and shake off excess water.
2. Stir the probe in the sample solution gently, leave it to stand. Wait
for the stability icon () to stay on screen, then take the reading.
3. Rinse off the probe thoroughly in distilled water after each test.
• If probe response is slow, we recommend soaking the probe in
12.88 mS/cm solution for 15 to 30 minutes to restore its
sensitivity. Re-calibrate the tester after rinsing. Please add
several drops of water into the cap to keep sensor activation
when storing the tester.
• The tester adopts 1413 μS/cm and 12.88 mS/cm standard
calibration solutions. User can use 1 or 2 point calibrations as
needed. For most circumstances, calibrating in 1413 μS/cm to
• Restore to factory default (P5) description: Select "Yes" in P5 to
restore the calibration to the theoretical values and parameter
setting to original values. When tester's calibration or
measurement performs abnormally, this function can be adopted
so the tester returns to factory default setting and then users can
conduct calibration or take measurements again.
Conductivity of the solution TDS factor (P2)
0to 100 µS/cm 0.60
100 to 1000 µS/cm 0.71
1 to 10mS/cm 0.81
10to 100 mS/cm 0.94
• Conductivity range (P1) description: Aut - all ranges: 0~2000
μS/cm, 0.01~20.00mS/cm. Once the readings are greater than
2000 μS/cm, the unit will automatically become mS/cm.
1 mS/cm = 1000 μS/cm. μS - only μS/cm range: 0~2000 μS/cm;
mS/cm - only mS/cm range: 0.01~20.00 mS/cm.
• TDS factor (P2) description: User can adjust TDS factor by
experimental data or experience. The following chart lists some
commonly used TDS factors for reference:

complete 1st point calibration will meet testing requirements.
• The tester has already been calibrated before leaving factory.
User can use the tester immediately or can test it in the standard
calibration solutions to evaluate its accuracy. If error is large,
calibrate the tester before using.
• We recommend replacing the calibration solution after 5 to 10
calibrations to maintain accuracy.
• The surface coating of probe sensor bar is firm platinum black
processed with special techniques. It improves measuring
performance and coating firmness. If the probe is contaminated. it
can be gently brushed with a soft brush in warm soap water or
alcohol.
