Can this unit be used to test PH?

FROM HM DIGITAL: The COM-100 is NOT a pH meter. It measures EC (electrical conductivity), TDS (total dissolved solids) and temperature. For pH, please purchase HM Digital's PH-200. For more information, please visit www.tdsmeter.com

no solo sirve para medir conductividad en los solidos totales disueltos (tds). saludos

Depends,A year or so maybe.I would test the PH with another testing kit from time to time.

There is no calibration. The button is only to get a reading on the meter but it will give you a true PH reading.

Yes and no. You can get it close with only 7.0 but for more accurate reading you need 4.0 and 10.0 or ph test strips (paper test strips)

That shouldn't be a problem. Set the unit on a higher alkaline level and don't run the water real fast. It gives the machine more time to raise the pH.

No, it is designed for testing moisture in dirt. If you use it to test the moisture in wet clay balls, or pebbles, it will either read fully wet, or dry. The air around the medium for hydroponics is either dry, or full of water during the flow and ebb cycle. The pH reading requires very wet mud, or liquid for a reading, but the reading isn't as accurate as pH test strips.

Yes. Use RO or drinking water and run threw zero water filter. PH up to 7.4 using ph meter to verify.

If you want to monitor your well water continuously, this pen will work, just make sure you calibrate it occasionally. If you just want a general idea of the pH of your well water, I'd go for a roll of pH paper strip.

Youre right, the PH range is 0-14. the picture reads 18.3 because the meter was turned on without being submerged in anything.

It only measures total dissolved solids, as gauged by electrical conductivity. If that will help you with nutrient levels, great, but I suspect the answer is really no.

It tests pH up to 8.8, Ammonia up to 8.0 ppm, Nitrite up to 5.0 ppm, and Nitrate up to 160ppm. Those are the only things you can test with this kit.

we have been very happy with our pH tester. It needs to be calibrated occasionally but for the most part stays in calibration fairly well. It's easy to recalibrate and easy to use. We are happy with the tester

what parameters does it actually measure ??? does it measure ph and ppm or is it just a moisture and light sensor?

This device has no temperature compensation mechanisms. If I recall, it suggests that pH values should be measured at "room temperature," however vague such a statement is.

Yes. The test strip has an indicator for total chlorine or total bromine. There is also a pool and spa range for the free chlorine indicator. The test strip has a pH indicator which can also be used for spa, however, the pH range is broad, so you might want a more granular pH tester.

I was looking online, and from my understanding, the pH won't be accurate, and the colors on the color cards won't be accurate, so you will not be able to interpret the readings, but the test results should be the same. Here's one forum that I looked at that can give you more detail:http://www.fishlore.com/fishforum/test-kits/41915-use-sw-master-kit-fw.html

Not really. It's most useful for chlorine levels that are in the goal range for a pool. It does give a rough estimate of PH and CYA (a pool thing) content. Doesn't test for bacteria etc, and not even that precise at what it does measure.
