## Questions & Answers

**Q: Does it measure manganese in water  ?**
A: This gives an overall measurement of all minerals. It provides a single number of parts per millions. It cannot provide a break out of the different minerals. Your local water utility/supplier can often give you the analysis of your local water. That is, they can tell you the amount of manganese in your local water. Hope this helps.

**Q: Does it measure the water hardness?**
A: Yes. The purpose of a TDS (Total Dissolved Solids) is to measure water hardness. The basic answer is the higher the number the harder the water. The lower the number the softer the water. The general rule of thumb is // 0 - 99 is ideal // 100 - 199 is good // 200 - 299 is average // 300 - 399 is marginal // 400+ is hazardous //. Like I said this is just general rule of thumb. The pen is actually pretty accurate for the price and has been effective for my shrimp tank.

**Q: batteries constantly drains and die even with product off! any one else with this issue or any ideas to fix?**
A: I have not had a problem with the battery draining...it has the same batter from when I bought it...

**Q: What is the range (ppm) of this meter?**
A: The Measurement Range: 0-9990 ppm

## Customer Reviews

### ⭐⭐⭐⭐⭐ So far seems to work. Very easy to use.
*by A***R on September 12, 2019*

Just got it today and started using it.Used a store bought distilled water and it was reading 002 ppm, which should be about correct since distilled water essentially is suppose to remove all impurities. Used it on our filtered faucet after water softener + filter and reading 377, and faucet without filter reading 406. Outside spigot (hard water) 460. These are PPM = mg/L. Dissolved 1 tsp of salt in 1 cup of water and reading 650 ppm but had a x10 symbol which means 6500 ppm. Using the distilled water as reference it seems to be pretty accurate. Will be installing a reverse osmosis filter instead. Will see what type of numbers this device will show.Very easy to use. Didn't really need to read the manual. Just remember the entire device is not water proof so don't try to dip the entire device into the water to measure.Update: 9/29/2019Installed the Brondell Reverse Osmosis filter today and got readings of 015, 025 while the regular sink without the filter was reading 356. This is softened water. Therefore, something must be working right. I've also notices some bottled or "natural spring" waters are reading in the 100 range which I assume contains some minerals, etc.So both the TDS meter and my RO filter is working. The RO filter is another story cause its leaking water.Remember: the TDS is total dissolved solids. It does not tell you what those solids are. I assume because of my water softening, its exchanging Ca+, Mg+ with Na+.Update: 10/4/2019Returned the Brondell, went to HD and bought the GE RO and didn't work, at least it didnt leak like the Brondell. Finally, Menards model worked. It was also the least expensive of the three. Easy install and worked like a charm. See photos of readings. Obviously the first is straight from the faucet with water softener while the second is through the RO filter.

### ⭐⭐⭐⭐⭐ Dead after 2 months
*by N***K on August 7, 2022*

I went to use this after having it for 2 months and it wouldn't turn on. Either the unit is bad or the batteries are dead, but the description says they should last up to 3 yrs. 2 months is a far cry from 3 yrs. After reading several other 1 star reviews I see that this is a common problem with this one. I will be buying a different one to replace it.

### ⭐⭐⭐⭐ good product and good price
*by C***. on January 4, 2024*

Easy to use and accuracy is okay.
