TDS meters Models TDS-EZ and TDS-3

Highly efficient and accurate thanks to its advanced microprocessor technology.
Hold function: saves measurements for comparative reading.
Auto power-off function: the meter automatically turns off after 10 minutes of non-use to conserve batteries.
Measurement 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 screen.
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 just 10ppm (0-9990ppm).

This HM Digital TDS-3 conductivity and temperature meter is pocket-sized, suitable for a wide variety of applications. It allows you to measure the purity of water by providing the Total Dissolved Solids TDS value in ppm. The term total dissolved solids (TDS) describes the total weight of the solid components (minerals, salts or metals) dissolved in water per unit volume which is measured in milligrams per liter (mg / L) or parts per mission (ppm) .
The use of a TDS meter is needed in: the production of clean drinking water, cleaning of swimming pool water, food, hospitals and medicines, aquaculture, domestic and office use, aquarium water, teaching of physics and chemistry, untreated water from electroplated, cooling towers, laboratories, ionized water and water quality analysis.

We advise you to regularly recalibrate the TDS meter with a suitable calibration solution for optimal accuracy.
