Digital Ph Meter / Water Quality Tester kit For Household Drinking Water, Hydroponics, laboratory, aquarium, swimming pools, 0.01 Res, 0.00 - 14.0 range, Calibration Buffer Solution Powder

Very fast and accurate reading! Used this meter to test the ph in my tap water and some of my favorite bottled waters. Was very surprised at how acidic some of them were. The calibration process was quick and easy and instructions were clear. Definitely worth the money.

Horrible and numbers just fly up and down 7 like this meter have no idea how to measure! Calibration another sick story, I never could stabilize the reading to go from one test to another .. it keep fluctuate to a point you will get sick from. Avoid if you can and find some more reliable PH Meter.

Meter failed two months after purchase. No response from vendor when contacted. Meter worked well and was accurate....when it was working. I'd purchase another, just not from this company.

Normally I use Ph strips for testing but I decided to try a meter instead this time. I figured it would be more accurate and would save me money overtime. The manual seemed well written but never having used a ph meter before, I felt like I needed to clarify a few things on how to calibrate it. So I contacted metersafe and they got back to me fairly quick. Really appreciated their willingness to help and response time. After having used it a couple of times now, I honestly don't see myself going back to ph strips.

This meter must be defective because when it is turned on it will not zero out to take your measurement. The numbers just constantly flicker and it never stops. After calibrating when placing back in the same solution it will read either higher or lower than what it was just calibrated to. I have been rinsing and cleaning after each reading but it still runs wild. I would like my money back or to receive a new meter. Very dissatisfied.

Took forever to calibrate....got it all set up and now it reads a different reading every time i test the same tank. Recalibrated two more times and still just reads whatever it wants to and not close reading either ...first reading 7.63 second readind 3.02 third reading 4.52 fourth reading 6.68 Decided to let it soak in distilled water for a few hours to. See if its just dry....no luck same odd ball random readings. Im not sending it back,not worth my time but i advise to buy from another source. Mines in the trash.

I have been using this monitor to measure the ph levels of my fish tank since I have received the ph meter. When I found out how important the ph level of the water is for my fishes, it was a no brainer to be able to make the measurements. After using the digital metersafe, I am happy to say that the readings have been very consistent and that my water levels are alkaline. My friends and I are new into raising fish, I'll definitely let them know about this meter!

Bad meter. Works for like 3 uses and then needs recalibration. Then after 6 uses the meter stops reading accurately and then gives you horribly wrong readings. Worthless. Bought 2 and the same thing happened to both. Recalibration stopped working on both within 3 days
