TDS & EC Digital Water Quality Testing Meter (3 in 1)

The device is CE and RoSH certified. The meter can be used for the test of TDS, EC and Temperature.  The probe is made of Titanium alloy which decreases the disturbance by the magnetism to the accuracy. 

Specifications:

• Testing range: 0 - 999 ppm
• Accuracy: +/- 2% (F.S.)
• Battery: 1x 3V (CR2032)
• ATC (Automatical Temperature Compensation): 0 to 60 degree
• Working temperature: 0 to 50 degree
• Weight: 50 grams
• Dimension: 156x30x20 mm
• A pouch for the device included

Introduction:

TDS, Total Dissolved Solids, is used for the evaluation of water quality. The reading means the miligrams of TDS per liter, ie. mg/L. The higher TDS reading, the more impurity content of the liquid/water.

EC, Electric Conductivity, it's reflecting the ability of electric conduction of ion dissolved in the water/liquid, indirectly indicates the content of ion, also can be used for the evaluation of water quality.

Importance:

• The device may not be used to test hot or flowing liquid/water.
• The device can be used to test the temperature.
• An example of classification of water by TDS: Purified water (TDS less than 50), Tap water (TDS less than 300). Image 2 above.
