Handheld Total Dissolved Solids TDS Meter and Thermometer for Aquariums, Ponds, Hydroponics, Pools

Total dissolved solids (TDS) are the total weight of all solids (minerals, salts, and metals) that are dissolved in a given volume of water, expressed in parts per million (PPM). The higher the TDS level, the greater the probability of harmful contaminants. Get accurate readings and learn more about your water quality and hardness with this Total Dissolved Solids Meter. This TDS meter measures water hardness in parts per million, ppm, by measuring electrical conductivity (ec). Displays total dissolved solids from 0-9990 ppm and temperature from 0-99°C. Excellent for use with home aquariums, ponds, and hydroponics systems where TDS ranges need to be monitored and tuned. Make sure your water filter is working and get to understand the hardness of your tap water by using the TDS meter before water changes or water top-offs. Too much dissolved solids in hard water can be detrimental to your equipment, livestock, or ecosystem balance. This TDS Total Dissolved Solids meter can be used to: C
