Avis sur le produitApera Instruments AI209 PH20 Value Pocket pH Tester Kit

Very nice!

Highly accurate, comes with easy to use n types of calibration solution (no mis by needed) and a nice case to keep everything together. My plants immediately responded to getting the water pH right.

Excellent pH meter

I purchased this because the cheap yellow meter I got was garbage. It was measuring pH of many solutions way off, despite having plenty of ions available (saltwater aquarium for example), and despite measuring both of the included buffer solutions perfectly! This meter is very fast, accurate and easy to use. The 1st day using it was a little slow to stabilize even after following the instructions for rehydrating the probe. My advice is hydrate the probe much longer the 1st time and buy some 3M KCl storage solution as recommended in the manual but not included, keep the probe stored wet and ready to go. From experience working with lab pH meters the storage solution should give you many years of life with minimal calibrations. The included case is nice but you'll need to find another way to store with the probe wet, I keep mine upright in a cup on a shelf, with storage solution in the included cap.Lire l'avis complet...

Wonderful device.

This unit is foolproof and so easy to use. Just don’t forget to buy some liquid for the sensor cap. Other than having to buy a $10 bottle of solution without knowing before the purchase, it’s awesome! My plant’s love the wonderfully Ph’d water now. Before.....m, not so much. It was 12.3 out of the tap with 326PPM. It’s out of an old well that’s fixing to be completely redone.Lire l'avis complet...

Simple and accurate

Well built, sealed unit. Uses normal batteries, not a stack of button cells. Calibration couldn't be easier. Easy instructions, including pictures for the impatient or adverse to literature. Includes calibration solutions for quick setup. Wish I had gotten one earlier and hadn't wasted time with those cheap yellow meters.Lire l'avis complet...

Great meter, great price.

I've used various such meters in the past but this one stands out for good accuracy with temperature compensation, rarely needing calibration, and a great price for what you get. Highly recommend it.

Good quality for the price. Reading varies sometimes

If used and stored properly it's a good meter for testing pH. The pH fluctuates on this meter even after the smiley face comes on which is why I only give 4 stars but for the price it's probably the best in its category. It will give you a good estimate of pH, much better than using dropsLire l'avis complet...

Good instrument. No complaints.

Great accuracy for the price. I've used it to calibrate my cheaper instruments, which were really off. Seems of good quality. Good accessories. Good plastic box. Having distilled water available to clean the instrument is worthwhile.Lire l'avis complet...

Thanks so much. Come by my flat. I'll make us up some Curry with Thai Basil, Lemon Basil, and Cinnamon Basil. Yeah baby!

Great price, works perfectly... guess what? Basil does not grow at PH 7.5! Wow! Now I know. Thanks!

Treat it right and it stays working and always use electrode storage solution

This is my third one since 2018 the first one I let the bulb dry out and this one was excellent for the price.

Works

A great quality PH meter for the price point. The meter is extremely accurate and includes a case and accessories. Easy to calibrate. Much better than expected.
