    Water Test Kit - TDS Meter - Instantly Check Your PPM Home Water Quality - Digital Tester for Drinking Well Water Hardness and Aquarium - Pool Testing PH Reader Pen 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.
