TDS Meter with 0–9990 ppm Range, 1 ppm Resolution, Hold Function and Carrying Case – HM Digital TDS-3
A TDS meter provides a fast way to monitor total dissolved solids in tap water, filtration systems, aquariums, hydroponic nutrient solutions, pools and spas. The HM Digital TDS-3 displays readings from 0 to 9,990 ppm at 1 ppm resolution, making it useful for repeat checks and comparisons across water sources.
Microprocessor-based operation, a built-in digital thermometer and a hold function help users capture and review measurements away from the sample. The meter turns off after ten minutes of inactivity to conserve its two included LR44 batteries. A protective carrying case with belt clip supports storage and field use. Listed readout accuracy is ±2%. This tool measures overall dissolved-solids concentration and does not identify individual substances or biological contaminants, so use appropriate specialized testing whenever the exact composition or microbiological safety of water must be confirmed.
