🎯 High Accuracy PH and TDS PPM Meter Pen Combo for Household, Pool, Aquarium, and Laboratory – Digital Tester with ± 2% Readout Accuracy and Temperature Meter Review

pH meter also changes when not in use. I returned the previous order and ordered another one but the problem is the same as last time. I lost time again.

The combination devices arrived very quickly. Each device comes with its own protective carry case, which is a huge plus for me. I compared the test results with more expensive devices and the readings are about the same. Definitely recommend this set for the price and performance.

I like the PH meter in this kit. It seems to work well despite the low price. However, if you want to check the total amount of dissolved solids in your nutrient solution, you should buy something else. I would have known beforehand.

I had a reverse osmosis water filter under the sink for a year and started replacing some of the filters as they were past their due date. Whenever I replace one and spend dozens of dollars I always wonder what am I buying for and what has changed? This TDS pen has finally answered all questions. Before the filter change the TDS is ≈60 (almost soft water) and after the filter change it drops to 30 (very soft). This gives me confidence in my water filter and can use it as an indicator for a…

Basically I got this pH meter combo kit but I will also be using a TDS meter to measure liquid dilutions of plant food - so that's it practically. The pH meter was pretty basic. To install. This takes about 20 minutes. You need: *) Distilled water *) Measuring cup (for liquids) with a milliliter mark *) Thermometer. The digital cooking thermometer works well.*) Microwave can be used. Measure out 250ml of distilled water. Use a thermometer to check the temperature - the closer to 25°C the better

Comes with powder so I can read and calibrate the pH meter accurately. It works well enough for home use, so I wouldn't force a scientific reputation on it. I somehow got two kits at once and they often have different opinions about pH even though they put it in the same solution at the same time. For this reason I kept them both; to see how they have maintained their accuracy and function. Also, I can use it for travel. This set isn't as "instantly readable" in seconds. I also believe the…

В основном я получил этот комбинированный набор для pH-метра, но я также буду использовать TDS-метр для измерения жидких разведений растительной пищи — так что That's convenient.

I have several pH meters, from a more expensive wall meter to many stick meters. I calibrate them regularly and always keep them moist in the right storage solution. This is the most inaccurate and unreliable meter I have ever purchased. Out of the box I calibrated it with all three solutions included in the kit. After calibrating I put it back in the 7ph calibration solution and it was off by more than 0.5. I recalibrated the device and then tried a different brand of calibration solution…
