Product Description: A TDS meter (aka ppm pen, nutrient tester, tds stick) is an inexpensive and convenient digital tool to instantly check your overall water quality. TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS-3 can tell you your overall water purity level, which will be displayed on the screen in ppm (parts per million). The lower the TDS level, the purer the water, with 0 ppm being pure H2O. The TDS-3 is great for checking your tap water quality, or knowing when to change a filter. (The meter does not test for biological contaminants.) The TDS-3 is a great tool for drinking water, water filtration and purification, colloidal silver, hydroponics (test your nutrients), aquariums, RO/DI systems, pools and spas, commercial and industrial applications and more. The TDS-3 is a rugged model that includes a protective carrying case. This is the world's most popular handheld TDS meter for industry professionals.

TDS Meter, Sonkir 3-in-1 TDS/EC/Temp Meter, Digital Water Quality Tester for Drinking Water Purity Test, Swimming Pools, Aquariums, Hydroponics, Measure 0-9999ppm (Purple)

 PartNumber: TDS   |   Asin: B07JWLP21H

Backlight Warning Function
Refer to the international standard, TDS value of 40 is the critical point for the purity of water. The lower the TDS level, the purer the water.
If TDS value is above 40, normally it indicates the water is very likely unsuitable for drinking, and hence the backlight of the LCD will turn out to be red while the test result of TDS is above 40.
However, the water with TDS value below 40 does not necessarily mean it is drinkable since there are various factors (e.g. bacteria amount) would determine whether the water is safe or not.

Automatic Temperature Compensation (ATC) Function
Since TDS value would be affected by temperature, this meter is equipped with Automatic Temperature Compensation (ATC) function for the highest accuracy purpose.

Specifications
Measuring Range:
TDS: 0 - 9999 ppm (parts per million)
Conductivity: 0 - 9999 s/cm
Degrees Celsius: 0 - 99 C
Degrees Fahrenheit: 32 - 210 F
Accuracy: 2% F.S
Battery: CR2032, DC3V; 230mAh
Working Temperature: 32 - 122 F
Net Weight: 1.45oz(41g)
Size: 6.39 x 1.16 x 0.64 inches

How to Use
