TDS Water Quality Tester used to test the value of water, electrical conductivity of water to determine the purity of the water with both test water temperature and environment temperature functions. It can industry,drinking water industry, household, personal home travel and field operations etc as the drinking water quality inspection tool.

1.Testing item : Water value ppm(mg/L),Conductivity us/cm, Celsius degree °C, Fahrenheit degree °F.

2.Basic. Fuction:

*[ON/OFF/HOLD]:

ON:in the off state, press this button to boot.

Auto-off:no operation,auto-off after 2 minutes

Manual shutdown: continue to press ON/OFF button 3s shutdown.

* [MODE]:default display test water conductivity us/cm value,press again, display Celsius degree °C ,press once to display

Fahrenheit °F; and then repeat the cycle above.

*[ClEAR] : reset, remove lock reading and re*test

Auto-test & Lock reading: insert into water can be auto-reading after reset.according to different water quality shows corresponding TDS value or conductivity us/cm. Then automatica llylocked.

*Scale fuction:according to national standard international practice.

*Direct dirnking water warning reference to national standrsd adopted TDS = 40 as a dividing line,<40 green backligh display for quallfied direct drinking water;> 40 red backligh display for non-dirnking water.

*Bcaklight function: low power backlight for night and low light places testing. At the same time it can be used as drinking water discrimination display.

*Large screen display: using high twisted STN thin transparent LCD display 4 numerical and corresponding physical units.

TDS rad range : 0-9999,identifier.

3.TDS rad range : 0-9999,identifier;

TDS testing range: 0-9999ppm

Accuracy: ±2% F.S

Temp:0-99°C&32-212°F, accuracy±0.1°F.S

Battery:CR2032*1 button cell(not include)

Use environment:0-50°C

Maximum relative temperature is 95%

1. Remove the protective cap.Press ON/OFF button.

2. Immerse the meter into the water/solution height no more than 4cm(From the beginning of TDS meter).

3. Waiting until the display stabilizes,the TDS Meter automatically compensates for temperature variations Once the readout is stabilized(30-45 seconds).TDS value stabillizes 4 seconds, instrument automatically lock readings.

4.After usage,shake off water from your meter or wipe it with a tissue.

 The platinum electrode design:

The EC series of high purity platinum sensor design, in the whole range of the measurement value to ensure accurate and stable.

The data lock: The EC series has a simple measurement value lock function, in the conductivity measurement mode, press the HOLD key, the instrument automatically locks the current measurement value, once again button, the instrument returns the measurement mode. 

1. Do not drop the entire TDS meter in water or dip beyound the maximum immersion level. This until is not water-warranty if water enters the unit.

2.Do not store the TDS meter under high temperature or direct sunlight . This will shorten the life-span of the product and potentially void the warranty.

3. Please avoid collisions, weight or fall.
