HM Digital AP-1 AquaPro Water Quality Total Dissolved Solids Tester, 0-5000 ppm TDS Range, 1 ppm Resolution, +/- 2% Readout Accuracy, Plastic, Pack of 1

This is a great product that feels premium and is very well built. It comes with a very sturdy box, and the included cell already had power right out of the box so I could use it immediately. It measured temperature and TDS only, which is exactly what I needed. My only minor critique is that I hope the display was a bit bigger for easier reading. Overall, it works perfectly and I would recommend it to others.

With the uncertain quality of water being supplied, this product is a must use product daily , to check the TDS count , and it gives you the choice to use or discard the water. Must Buy item for a sound health.

High accuracy

The product is good and works fine. The only issue is the product description and image where it shows it has magnetic property and can be attached to refrigerator but there is no such feature available.

Hello, I was drinking Cauvery water for many years in BSK 3rd Stage, Bangalore but was unsure of the TDS levels. I bought this HM Digital AP-1 tester and found useful. Its reliable and gives accurate readings which incidentally made in Korea product. The municipality water level TDS was around 200 ppm and then went for RO+UV+UF+TDS water filter to get good, clear, potable water. The technician set the TDS limit in the water purifier to the desired level and now the family is liking the taste of water. The TDS level reduced to 60ppm. Anything around 50-70ppm range is a good water as we need some minerals for the body, hence water purifier was not set for below 50ppm. Thanks,

1. The product is definitely very good. The packing was completely open from one end, as a result of which I initially got a feeling of it been tampered. But it was a genuine piece. I rated 4 only because of the damaged packaging which I think is very important for any genuine product. 2. The TDS of bottelled Bisleri water was 40. My tap water at Malad West was 76. 3. I would like to do some more tests from some other places and sources and give an update as and when it happens.

I have no way to check the accuracy. I checked it on piped surface water from river with 24 ppm TDS, well water with 49 ppm and groundwater with 160 ppm which is expected as per the taste, residue on drying etc. of the tested waters.

Buen medidor tds teniendo en cuenta su bajo precio. Una lastima que las instrucciones vengan en inglés. No hay instrucciones en español.

Alles o.k. gerne wieder
