Hand Held TDS Meter

Hand Held TDS Meter


EWP-USA's hand held TDS meters are the digital substitute to standard TDS test kits. They utilize the latest digital technology in water testing, are cheaper than than test kits over the long run, and are accurate.   The meters can be used for aquariums, swimming pools, the fishing industry, the food/beverage industry, and etc. 

Each meter comes with a black carrying case (with belt clip), two batteries installed, and the manual.



  • Hold Function: Saves measurements for convienent reading and recording
  • Auto-off function: The meter shuts off automatically after -10 minutes of non-use to conserve batteries
  • Measurement Range: 0-9990 ppm. From 0-999 ppm, the resolution is in increments of 1ppm. From 1000 to 9990 ppm, the resolution is in increments of 10ppm, indicated by a blinking 'x10' image
  •  Built-in digital thermometer
  • Display: large and easy-to-read LCD screen.
  • Factory Calibrated: our meters are calibrated with a 342 ppm NaCl solution. Meters can be recalibrated with a mini-screwdriver.
  • Also available in "x10" mode: reads in increments only of 10 ppm (0-9990 ppm).
