Description :Digital 3 In 1 Tester LCD TDS EC Meter Temperature Conductivity Water Filter Purity Liquid Qualilty Testing PenTDS water quality measuring pen is used to test the water TDS value, water conductivity, to determine the purity of water. At the same time both test the water temperature and ambient temperature function. Products can be widely used in water treatment industry, drinking water, family, personal home tourism, field operations as drinking water quality inspection tools.
Specification :

|
| CLEAR Key Function |
Clear the lock read and re-test |
| MODE Key Function |
The default display test water quality total solid dissolved amount ppm; Temperature ℉; then repeat the cycle to display the above |
| Scale function |
According to national standard scale. And with appropriate reference to international practice. Direct drinking water warning with reference to national standards using TDS = 40 for the dividing line. Less than 40 show green backlight, for qualified straight drinking water, more than 40 show red backlit, for non-direct drinking water. |
| Backlight Function |
Low-power backlight, easy to night and light dark place for testing use. At the same time as a direct drinking water to determine the show. |
| Large screen Display |
High distortion STN thin liquid crystal, display 4-digit value and the corresponding physical unit |
Operation :
1, Take the pen and open the ON / OFF switch.
2, The pen into the solution to be measured, the solution height can not exceed 4cm (from the beginning of the pen).
3, The pen gently in the test solution to stir a few times, such as reading stability. The measured value of the TDS is greatly influenced by the temperature, so the temperature compensation is used to correct the reading. The data shows the stability of the lock automatically after the lock. To manually lock, press the HOLD key. To re-test, press CLEAR key to clear, and then re-test. Press the MODE key to achieve the test function selection, in turn select: ppm, conductivity us / cm value, Celsius temperature ℃, Fahrenheit temperature ℉.
4, After use, with a cloth to dry the pen part of the water, the pen sets back.
5, Press the ON / OFF button 3S, can be manually shut down.
Note : 1, please avoid the TDS test pen soaked into the water.
2, please avoid high temperature, direct light.
3, please avoid the impact, weight or fall.
