is this meter the cheapest among similar meters? does it really have 1 ppm resolution?

Yes this meter has1 ppm resolution but it is not laboratory quality. If you really need 1ppm accuracy then break out your check book and buy a professional instrumen
2020619
no, not anywhere above 1000 PPM it shows only the first three digits, less than 1000, it does show three like 875 for example. Above 1000 you get 113, that could be any where between 1130 to 1139. but it is still working after six months.

FROM HM DIGITAL: We also have a more basic model called the ZT-2. The TDS-EZ is inexpensive, not cheap. Yes, the TDS-EZ really has a 1 ppm resolution (up to 999 ppm). From 1000-9990, the resolution is 10 ppm.

it's not expensive. sophisticated enough for the intended use. I am satisfied.

I have one of these. I use it TI monitor the effectiveness of my RO filter module. It works great and it is cheap. Since I am not a testing lab, I can not say that it has 1 ppm resolution, but I can tell you it very well may.

Yes, I found it to work very well, comparing tap water to distilled water it showed the contrast of 0 to 220 ppm

yes you will but you can get a meter cheap from amazon I have one works good

This is a simple Volt Ohm Meter. It works, and was quite cheap. I use it for small projects like testing battery status, but it might work fine for your task. Obviously there are many available at Amazon that are of much higher quality, but the price will be more. I would expect you should be able to test areas of your circuit to see where current is still being applied when the switch is off. Do take notice of the ratings for what it can handle.

Sorry Calvin, I think this a great meter, however, I only use it to check the voltage on my AA and AAA batteries and rechargeable batteries from Amazon..... Works Great ! Phil Pauls Valley, Oklahoma

Confused by your question. It will measure for example a solution of say 1500ppm or 2000ppm. But measurements are in ppm (parts per million), not ppt (parts per thousand).

Yes, as long you select the port COM in your program.Am using it with OPENCPN and have done accuracy test with less than a meter as result.

Display usually reads 0.01-0.02 with probes in contact with each other in the 0-1K range. It is a great meter for the price.

This meter will not hold the highest value on the display. You would need to "watch" it all all times

I used this meter for general use low voltage 1v -28v dc and some 110v ac. This meter is auto ranging. Looks like your looking for meter that measures milli volts below 1 volt I would not buy this model.

There are quite a few and different manufactures. The solution is based on what you intend to use the meter for. For example you might what to use a solution that has a PPM of 1000 for general use. If you plan on using for hydro you probably would use a 1500 ppm solution as it's a matter of using something that reads towards the high side of your intended solution. Most TDS meters will have instructions or a sachet of solution inside so that one will be the units best option unless it is way off from intended use.

I don't know. I use this for domestic applications only. I bought it because none of my old meters were Catagory 3.

yes but remember you voltage is close to max, my max with PV is 19.2, the meter works great. DS

Clamp resolution is .01 A or .1 A. The meter also can function as regular multimeter using lead wires. In such case the resolution can be selected as 1 microA or .1 microA. A word of caution - do not confuse resolution with accuracy.

The meter only has a guage that reads, 0 to 2000 on top and 1 to 10 on the bottom of the line...I only paid less than $4.00 for the meter including shipping from China... It has saved me from over watering. The meter seems to be working ok but I don't know how accurate it is... For a cost of less than $5.00 it can't be too percise...

Yes and yes. Although it's not as accurate as a calibrated broadcast monitor, there's enough resolution to get the job done. Good luck to you!

The max output of a usb will widely vary depending on what you attach to it. If you are using this to just measure output from a non-usb thing, this meter may not work at all. For example, if I use a special charging cable that is not a data cable, this meter does not work.

FROM HM DIGITAL: The COM-100 will read over 999 in any ppm mode. The meter has a 3-digit LCD screen, so if it's over 999 ppm, you will see a flashing "x10" icon, indicating that the reading needs to be multiplied by 10 for the actual measurement. danK's example is correct - 142 with the "x10" icon is really 1420 ppm.
