Pros: Precio imbatible, construcción sólida y fácil sistema de calibración. Yo lo utilizo para control de agua de Acuarios y para este menester tiene la suficiente precisión (un decimal). Por el precio de un sistema colorimétrico e infinitamente más preciso. Cons: Se echa de menos un sistema de apagado ... Read more
Very cheap, in other stores i found the same article about 1.5/2 time more expensive.
Very easy to use and easy to regulate with the included screwdriver.
The box is very useful. The batteries have a short lifetime but with few dollars you can overcome this. I use it to measure the ph of my aquarium ... Read more
Easy to calibrate.
Fast and accurate measurements.
Good manual in clear English.
Solid pH test pen. Nothing flimsy about it. So far no cons.
(Except the cons that go for all pH testing devices like distilled water and buffering solutions required to calibrate and needs frequent calibrations) Nothing ... Read more
An easy and fast way to measure pH. Actually I'm using it in aquariums and seems to be very accurate. If you have paper pH tests or even the liquid tests (the one's displayed in color ranges), you do not need the powder for creating the solution for adjustment. You just do it comparing to your common ... Read more
Really functional and easy to use ph meter. I would say that for the price it costs it is accurate enough. Comes with a nice box with instructions and all the things you need to calibrate it. Not really a con but the ph meter is bigger than i was expecting. Also it is made of plastic, seems fragile but ... Read more
Good tester, easy to calibrate and operate. It provides persistent measurement results. Very good to use for aqua/aeroponics or fish keeping. It comes with calibration solutions ( dry, just add water to produce solutions). I had to purchase 2 of them, cos first i received had senser damaged, so te pen ... Read more

- even a mini-screwdriver to adjust it

excellent instrument for measuring ph.
as effective as three times more expensive models.
Fast test in 3 seconde !
it is a little more accurate than the test liquid it does not look very solid but hey it is not done playing with.
the screen is a bit small but still readable even. you need distilled water ... Read more
For the price, is definitely a good deal. I don't have any other ph meter to compare with, but after calibration is pretty accurate. I measure ph of some bottled water and the measure was the same as indicated in the bottle. I reccomend! The calibration is a little annoying. I have to buy distilled water ... Read more
