Yes I can see the numbers but they are wrong. Really needed accurate readings so I ordered this. I have 1000 ppm calibration solution I ordered specifically because this was giving me crazy numbers.There is no way to calibrate it. I sent a message through Amazon to the seller and received an automatic “their email is incorrect.”I will attempt to get a refund or replacement. At this time with COVID cases it is not worth going somewhere to shop it back.In 1000ppm solution it reading over 1500 with correct temps.

I received the unit and could not get it to turn on. Looked for a tab where the battery is to activate the battery...no tab. Thought the battery may have been installed upside down. Still no go. Got my volt meter and checked the battery. DEAD AS A DOORNAIL. Thought about returning it but bought a battery instead and it began working. They should keep the battery separate from the unit and let the buyer install it...super easy. Also wish it had a backlight as it's hard to see depending on the light in the room. Appears to be fairly accurate but the design and packaging could be far better.

I had my water tested and compared their results with the meter, no where near 2% accuracy. There is no way to calibrate. Unfortunately it is too late to return. DO NOT WASTE YOUR MONEY!

Worked with the company and they replaced unit free of charge without me returning the unit. Second unit still inaccurate. Company did not want to try a third unit, but did refund my original purchase price.Went with an HM unit and is highly accurate.

The reading is extremely off from the other TDS meters in my fish room. It is 30 PPM higher than one and 25 PPM higher than the other TDS meter. This is extreme and not helpful to me. I figure you get what you pay for! On the positive side, the temperature accuracy is dead on target! The only reason I gave it more than one star. A backlit led would have greatly improved this tool.

Was looking for one and I wasinly seeing very expensive ones. Then I stumbled on this one and the price was perfect compared to others. So we tried it,oursseems to be ok and calibrated ok. I seem to be having good luck with it.

The reading on this water tester was very good. I needed one of these to test my tap water and I found out I should not drink it. I tested my bought bottled water and it was okay. I thought I could save money form buying bottled water but I found out I could not so this water tester give me the answers I needed.

Does ok but is made cheaply.
