## Overview

The HM Digital TDS-3 is a compact, battery-powered handheld meter designed to measure Total Dissolved Solids in water with a wide 0-9990 ppm range and 1 ppm resolution. Featuring a large LCD screen, built-in thermometer, and a hold function, it delivers ±2% accuracy for precise water purity readings. Ideal for professionals and enthusiasts alike, it comes with a durable carrying case and belt clip for convenient field use across applications like filtration monitoring, hydroponics, and aquariums.

## Description

Product Description: A TDS meter (aka ppm pen, nutrient tester, tds stick) is an inexpensive and convenient digital tool to instantly check your overall water quality. TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS-3 can tell you your overall water purity level, which will be displayed on the screen in ppm (parts per million). The lower the TDS level, the purer the water, with 0 ppm being pure H2O. The TDS-3 is great for checking your tap water quality, or knowing when to change a filter. (The meter does not test for biological contaminants.) The TDS-3 is a great tool for drinking water, water filtration and purification, colloidal silver, hydroponics (test your nutrients), aquariums, RO/DI systems, pools and spas, commercial and industrial applications and more. The TDS-3 is a rugged model that includes a protective carrying case. This is the world's most popular handheld TDS meter for industry professionals.

Review: Perfect checking water filter performance - After a month’s use monitoring drinking water, I've found it accurate and consistent. The unit delivered came with batteries and a carrying case included. Also included was a note from the suppliers asking me to get in touch if I noticed any errors - nice touch. Some reviewers have noted continuing varying read outs. I've noticed something similar when used with hot water but didn't find this a problem as it was mostly used with room temp water. In my opinion, it's accurate to within plus/minus 2%. This is based on ongoing readings given on municipal water, distilled water and stored samples. Granted, these aren't 'standard' samples but over time these samples confirmed the unit's accuracy and repeatability, in my opinion. I bought it to use as a quick check on my Brita water filter's performance and this it did admirably.
Review: Excellent product, really simple to use. - I use the product to test my fish tanks and pond water. Also test my tap water.

## Questions & Answers

**Q: Does this TDS compensate for differences in temperature like the HM Digital TDS-4?**
A: Yes if it was a real HM TDS meter but it is not.  It's a knock off.  Go to manufacturer's webpage and find a dealer in your area and order it there if you want a real meter.  
I spoke to the manufacturer HM DIGITAL today and they said the photo of this product is an original, but the product they ship is NOT.  The original real HM Digital TDS-3 have a printed instruction in black letters on the back of the meter that says "CALIBRATION" and has a screw to calibrate.  The knock-off simply has a hole and no printed words about calibration on it.  The original also has 5 bumps on each edge of the meter like the photo, but the one this seller ships does not.  Lastly, the real HM TDS-3 will display "HM" on the screen when you turn it on and then will display 00, but when you first turn it on will display HM.

**Q: Where is this item made?**
A: This is a a knock-off.  I spoke to the manufacturer HM DIGITAL today and they said the photo of this product is an original, but the product they ship is NOT.  The original real HM Digital TDS-3 have a printed instruction in black letters on the back of the meter that says "CALIBRATION" and has a screw to calibrate.

Lastly, the real HM TDS-3 will display "HM" on the screen when you turn it on and then will display 00, but when you first turn it on will display HM.

**Q: Does this teat for lead , mercury, cadmium and other metals? If so, does it tell you concentrations?**
A: No, it does not test for any specific dissolved solid. It tells you the purity of the water only. In other words, how close is the water sample is to distilled water.

**Q: The one I bought seems to work however it has no way to adjust it there is a hole in the back but no screw is it a imposter?**
A: That's because it's a knock-off.  I spoke to the manufacturer HM DIGITAL today and they said the photo of this product is an original, but the product they ship is NOT.  The original real HM Digital TDS-3 have a printed instruction in black letters on the back of the meter that says "CALIBRATION" and has a screw to calibrate.

### ⭐⭐⭐⭐ Happy with it so far.
*by I***N on 4 July 2021*

So far the HM Digital TDS 3 seems to work fine. Only used it once so only 4 stars as I have not had enough time to determine its accuracy, perhaps 5 stars is deserved. It's easy to use one read and so far I have no issues with it.
