User questions & answers

Question:	Can I use this ppm meter for hydroponics
Answer:	Yes . This is one of the intended uses :) Just please note it's for TDS (Total Dissolved Solids), not for pH. In hydroponics applications, a ppm meter such as this one is used to determine your nutrient count.
Question:	how can i test if the unit is accurate could i use distilled which i assume should be zero, thanks tom
Answer:	Thanks for your question. This TDS meter is pre-calibrated in factory, no need calibrate again by customer, we do this to prevent as many calibration related mistakes as possible, and it's easier to use. To maintain the accuracy, it's better to rinse the probe with distilled water after each use. For your mentioned distilled water, it should read 0 ppm theoretically, but in actual application, if you can't keep test condition very clean, it may read 0-2ppm usually.
Question:	Can this also check for ph
Answer:	It Does not. It measure TDS , EC and Temperature 3 in 1. PH Meter is another tester.
Question:	What kind of battery does it have
Answer:	1 x 3V button battery CR2032 , it's included in the water tester. Sincerely hope you enjoy the products we sell on Amazon!

User questions & answers

Question:	Does this test for Ferric or Ferrous iron
Answer:	Yes, the strip can test for Ferrous iron.
Question:	For the manufacturer - is one single drop from the dropper directly onto the test pad (one for each) a sufficient amount of water to test the levels
Answer:	Yes, one drop for each pad is sufficient. Please rinse the dropper 2-3 times with the testing water before using (just suck the water in and squeeze it out). This is to clean/prepare the dropper. The other thing is, we use special coat on each testing pad to avoid water running from pad to pad, and you can see the water drop is contained within each pad. If you find it is not easy to read the colour with excess water, you can gently shake off the excess water on the strip, AFTER waiting for 30 seconds so the colours have fully developed.

User questions & answers

Question:	does it test ph
Answer:	No, it test for TDS in PPM (parts per million). The reading is taken from the EC reading and converted within the unit to TDS. This is the accumulation of all dissolved solids in your water. But what conversion factor is used by this company? A 5.0 conversion will have different reading than one with a 7.1 conversion factor. Makes a difference. Learning to read EC is best option along with a tester that reads EC and PPM. No calibration on some. To test your pH you can use the paper strips, General Hydroponics sells a pH Test Kit that includes testing solution along with pH Up and pH down for adjusting your pH to your requirements if you are into gardening. Very fast and easy to use. There are a number of pH test pens on the market. Most need calibration and calibration solutions that is a consumable. There are different calibration factors on these as well. But easier to use and more accurate once you learn it.
Question:	At what reading should the filter/cartridge be changed
Answer:	Your filter and cartridge should be change every 30 days , if your ppm reading over 300 you may need do some water change , also test for nitrite , nitrate and ammonia . under 300 ppm you are OK , should be around 150 ppm to 250 ppm , but not over 400 ppm . usually do 10% water change every month or twice a month depend on how many fishes or shrimps you have. Hope will help.
Question:	Is there a minimum amount of water that can be tested
Answer:	I just put some water in a cup and put end of TDS gauge in, no more than inch. By the way, the best water will test 0. I use a zero water pitcher. I use this to check if new filter is needed. I hope this helped you.
Question:	What is the accuracy of this tester
Answer:	Can’t say for sure. Howerver, the first time I used it, the number I was getting from an old RO membrane were 350ish. I thought for sure the meter was in error. I then opened a bottle of filtered water and tested that. The bottled water reading was 12 so I think the meter is very accurate. I have since replaced the RO membrane and my numbers are in the high 20s to low 30s. I hope this helps. I would highly recommend this tester - it’s a great buy.

User questions & answers

Question:	can the battery be replaced? if so, what battery does it take
Answer:	Yes, the batteries can be replaced. It takes 2 LR44G "button cell" batteries like the batteries that go in watches, ect. The unit has an auto shut-off so the batteries should last a good long time.
Question:	Can this be used to check for collodial silver in the 10 ppm range in a solution of distilled water
Answer:	No it can't. It doesn't detect specific elements or chemicals. Though the way calcium, lead, and collodial silver may dissolve would effect the numerical value of TDS and if you knew that in 100 ml of 45 deg Celsius water would only hold X# ppm of an element you might be able to figure it out based on the numerical value shown.
Question:	What temperature was this device calibrated at? I noticed that readings vary with temperature. How do I get a consistent reading
Answer:	FROM HM DIGITAL: The TDS-EZ was calibrated at 25 degrees Celsius (77F), but more importantly, the TDS-EZ is one of HM Digital's most basic meters and does not have Automatic Temperature Compensation (ATC). Therefore, since it does not have ATC, you will see discrepancies when testing hotter or colder from the baseline of 25C/77F.If your water is typically around this temperature, it won't be much of a difference, but if +/-10 degrees or more from 25C/77F, it's a good idea to get a meter with ATC, such as HM Digital's TDS-3, TDS-4, AP-1, COM-80 or COM-100.
Question:	How many times can the tester be used
Answer:	FROM HM DIGITAL: Unlimited. Eventually, you will need new batteries, but the TDS-EZ can be used an unlimited number of times.

HM Digital TDS-EZ Water Quality TDS Tester, 0-9990 ppm Measurement Range

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-EZ 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-EZ 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-EZ is a great tool for drinking water, water filtration and purification, hydroponics (test your nutrients), aquariums, RO/DI systems, pools and spas, and more.

User questions & answers

Question:	How can the TDS meter be calibrated
Answer:	People's preference is to use what is called a wet erase chalk marker. It is a marker with chalk that only comes off when you use water. It doesn't come off when just rubbed by a dry hand. We don't include a chalk marker with these labels as the markers have a tendency to dry up if stored a long time, and we prepackage this set. However, you can easily find a big selection on Amazon including ones with pretty colors. Search "liquid chalk markers" or "wet erase chalk markers." Becky for Cornucopia Brands
Question:	Does this include a battery
Answer:	These glass bottles are manufactured in China. They are in transit 3-8 months before they reach a customer. Becky for Cornucopia Brands
Question:	How long does the readings take
Answer:	Yes, it’s good quality solid glass. It’s even more safe for food type liquids than other bottle types like plastic; because chemicles and things from plastic bottles can seep in if/when the bottle is heated.
Question:	Does the tester take the temperature of water
Answer:	These don't come with separate caps. The sprayers have an OFF setting to close them. Becky for Cornucopia Brands

User questions & answers

Question:	Could these be used for testing the pH in a jar of canned food? Why or why not? Would it give you a reading to the .01 degree
Answer:	it's a general purpose ph meter and would suffice for most typical purposes. you can test any liquid or similar that you can dip it into. if you want something that's lab grade I mean common sense is pay more for a better one. so the question is do you have a requirement for something that may be better, or will this do for you at a pretty cheap price see less
Question:	Can i put the ph / tds tester in the swimming pool and aquarium? is it waterproof all over
Answer:	No, Don't put into the water, because there is a battery cover, it's not waterproof, and the water level should not be immersed in the immersion line during the test.
Question:	Does the pH meter work for a saltwater swimming pool
Answer:	Yes but these ph meters do not work very well in general. Better to either use the test strips or a reagent pool test kit
Question:	Can I possibly stick this meter in soil and it give me an accurate reading
Answer:	No, the reading is not displayed in this way, because this is the aquarium ph meters of the test liquid
