How many times can the tester be used?

I do not believe there is a limit. It does take a small battery but it is included and probably lasts many dozens of hours. It just is not actually on that long and goes off by itself. We test our water every so often and is very handy and ready to use.

This TDS tester is an electronic device that can be used indefinitely. It has two metal probes that are submersed in water when taking a measurement. After the test is completed, excess water is shaken off of the probes; and a protective cap is replaced to protect the probes from handling damage. There are no consumable parts to this tester, other than batteries. With careful handling, this device should probably last several years. The most probably reasons for it to quit functioning would be breakage from dropping onto a hard surface (e.g., kitchen floor), submersion from dropping the device into water, or the batteries going dead from use or long storage, in which case the batteries could be replaced.

If it is cared for per mfrs instructions*, it has an indefinite life. It will need periodic battery changes - I have no idea of that interval. *Don't immerse beyond 2", shake water off, let it dry before putting the (also dry) cap back on.

FROM HM DIGITAL: Unlimited. Eventually, you will need new batteries, but the TDS-EZ can be used an unlimited number of times.

More than one.... I'd say 10 or so depending on the amount you use it each time

My tester does without problem. I am very pleased with this tester, more so than the others I own.

I have only used mine two or three times and I haven't noticed a problem. I keep mine set on 3 just about all the time.

I actually used mine one time. Was after the time frame to return, and it did not work correctly. I actually threw it out as it seemed dangerous.

I don't know not know how many times in total, but according to the times I'd say clean it about 15 or 20 times

if you are asking if you can change the code on the meter to match the test strip, yes you can, however, for about at least 4 years now, all one touch test strips have only one code; 25, so you shouldn't have to keep recoding once you've coded it to 25, but always double check the code on the test strip container to make sure. I guess they did this to compete with all the "NO CODING NEEDED" meters.

Yes, you can do it as many times as you want. As a matter of fact, my daughter used it more than my son. There are many projects you can perform with this set. I think it's well worth the money. You can do the same experiment an infinite amount of times.

Hi, That happened to me, the chip for the tester is overloaded or burnt out. Just tell the seller and they should ship you a new one. When it is confirmed you are being shipped a new one, just strip the old one for parts

Absolutely, I test mine a couple times a year. This tester works best when connected to the battery's post.

Not two of every test. Although it has been long enough I do not remember which test was just one. In short you would need two kits for before and after.

not many times, maybe about 10 times, dont really use it much as it is my spare

after drying it out, press the battery test button. if you get at least one iight then its probably ok to use

I purchase the 2 test kit at a time. That way I do not have to worry about expiration. I test every 2 to 3 months.

One time use, but for multiple tests. I bought 2 kits so I could test at my meter and after my osmosis.

Yes we can. The tester splits into two parts. The parts are connected , one to each end with the main part with display at the end where you want to see the result.

Hi, I'm not sure...I had 20 in mine when I received the tests. Good question!...
