TDS Meter

  • AP-1 AquaPro Water Quality Tester

    • Measures total dissolved solids (TDS) and temperature.
    • Automatic Temperature Compensation (ATC)
    • Water-resistant housing
    • Measurement Range: 0-5000 ppm
    • Digital Calibration (push button)
    • Auto-off function, data-hold function and low-battery indicator.
    • Display: large and easy-to-read LCD screen includes simultaneous temperature reading
    • Factory Calibrated: The AquaPro is calibrated with a 342 ppm NaCl solution. The meter can be recalibrated with digital calibration using the push buttons, rather than a screwdriver.
    TDS Range: 0-5000 ppm (mg/L)
    Temperature Range: 0-80 °C; 32-176 °F
    Resolution: 1 ppm; Temp. resolution is 0.1 °C/F
    Accuracy: +/- 2%
    Conversion Factor: NaCl (avg. 0.5)
    Calibration: Digital calibration by push button.
    Housing: Water-resistant

  • TDS-3 Handheld Meter with Carrying Case

    Ideal for all water purification applications, wastewater regulation, aquaculture, hydroponics, and colloidal silver. Perfect for both consumer or commercial use. Carry one in your pocket or toolbox at all times!

    • Ideal for commercial use. Includes a carrying case with belt clip.
    • Highly efficient and accurate due to its advanced microprocessor technology.
    • Hold Function: saves measurements for convenient 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).

    TDS Range: 0 - 9990 ppm (mg/L)
    Temp. Range: 0 - 80 degrees Celsius
    Resolution: 1 ppm, 1 degree Celsius (also available in 10 ppm)
    Accuracy: +/- 2%
    Conversion Factor: NaCl (avg. 0.5)
    ATC: Built-in sensor for Automatic Temperature Compensation of 1 to 50 degrees Celsius (33 to 122 degrees Fahrenheit)
