Display Type:Digital With Backlight Or Not:No DIY Supplies:Electrical 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 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 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 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 is a rugged model that includes a protective carrying case. This is the worlds most popular handheld TDS meter for industry professionals. ts Ideal for Commercial Use Its Includes a Carrying Case with Belt Clip Hold Function: Saves Measurements for Convenient Reading and Recording Highly Efficient and Accurate Due to Its Advanced Microprocessor Technology Built-in Digital Thermometer, Display: Large and Easy-to-read LCD Screen.
