HM Digital's AquaPro series of handheld TDS/EC meters offer a sleek design perfect for today's modern kitchen. AquaPro digital water testers are the next generation for today's tech-savvy and health-conscience consumer.

 

Every household should have one!

 

USES

  • Test you tap water
  • Check you water filter
  • Traveling
  • Aquariums
  • Pools & Spas
  • Botttled water

Why you should test your water.

 

As a crucial part of our existence, we must be certain the water we consume and provide for our families is of high quality. Tap, well, and even filtered water is prone to fluctuation and possible contamination. Testing regularly enables you to be sure of your water's purity.

 

The AquaPro digital water tester is your first step to high-quality water. With the push of a button, the AquaPro measures TDS, an indicator of general overall water quality. The lower the TDS, the purer the water. However, the AquaPro digital water tester does not detect bacteria, microorganisms, or organic chemicals.

TDS & EC Calibration

  1. HM Digital meters come factory calibrated (at 342 PPM or 1413 µS, depending on the product) and are ready to use out of the box. They are designed to stay consistent. However, after prolonged usage, it may help to recalibrate your meter using a commercial standard NaCl-based solution (for most HM Digital meters), which is approximately, 0.5 µS of conductivity.
  2. Immerse the meter into the calibration solution. If the meter does not read within 2% of the calibration solution, adjust the reading by either digital calibration (for some products) or inserting a mini screwdriver (not included) into the trimmer pot (the hole on the back of the meter). Turn the trimmer clockwise to increase the reading and counterclockwise to decrease the reading. Note that the adjuster is very sensitive. Always refer to the calibration instructions for your particular product.

Note: HM Digital products are calibrated with a 342 PPM NaCl or 1413 µS solution. This is suitable for most applications. However, if you are measuring samples that are consistently over 1000 PPM, it is recommended to recalibrate the meter for that specific application. TDS meters are more accurate when calibrated at levels that are as close as possible to the sample being tested (such as for hydroponics, aquaculture, tinting and dying or brackish water).
