Description
TDS meters TDS-EZ and TDS-3 models in water.
The TDS (total dissolved solids) meter is highly efficient and accurate, thanks to its advanced microprocessor technology.
Hold function: saves the measurements for a comparative reading.
Auto power off function: the meter automatically shuts off after 10 minutes of non-use to conserve batteries.
Measuring range: 0-9990 ppm. From 0 to 999 ppm, the resolution is in 1 ppm increments. From 1000 to 9990 ppm, the resolution is in 10ppm increments, indicated by a flashing ‘x10’ image.
Display: large, easy-to-read LCD display.
Factory calibrated: our meters are calibrated with a 342 ppm NaCl solution. The meters can be recalibrated with a mini screwdriver.
Also available in “x10” mode: reads in increments of only 10 ppm (0-9990 ppm).

This TDS or SDT conductivity and temperature meter HM Digital TDS-3 is pocket-sized, and is suitable for a wide variety of applications. Allows you to measure water purity by providing the TDS Total Dissolved Solids value in ppm. The term total dissolved solids (TDS) describes the total weight of solid components (minerals, salts or metals) dissolved in water per unit volume measured in milligrams per liter (mg/L) or parts per mission (ppm).
The use of a TDS meter is needed in: clean drinking water production, pool water cleaning, food, hospital and medicine, aquaculture, domestic and office use, aquarium water, physics and chemistry teaching, untreated electroplating water, cooling towers, laboratories, ionized water and water quality analysis.
We advise you to recalibrate the TDS meter regularly with a suitable calibration solution for optimum accuracy.
