Apera Instruments SX610 pH Meter, Pen Tester, Waterproof , ±0.1 pH Accuracy, 0-14 pH Range, ±0.5°C Temperature Sensor

Comes with everything you need for continual and accurate PH readings. Way better than the cheap options I took first (my mistake!). I recalibrate using the solution supplied around every 4-6 weeks. Great we unit and comes in a quality case to keep everything together and protected.

Great ph meter, super easy to calibrate and use, really quick to take readings! comes with buffet solution, soaking solution and spare battery!

light, accurate, ideal for our industry

Will not calibrate. I have followed the instructions to the T and have tried several ways by pressing the button for 2 second up to a minute yet it still won't calibrate. I have contacted apera who are trying to help but if all else fails I will be looking for a refund

been in use a few months now still quick and accurate as when first bought, decent price would recommend.

I've been using pH strips for my fermentation business. This is so much more precise and clean. Love it!

I bought x2 ph pens,both useless so i upped the ante,this hit the spot,please dont buy the cheap ones

As with many people here, mine worked well for a while and then stopped calibrating. Customer service required me to post it to Germany at my cost to see of it was damaged or if it was faulty. I left it in cleaning solution for several days and it still wouldn't work, but then gave up on it and after several weeks of being in cleaning solution I tried it again and it was working fine. It's obviously a flaw of this model, but it is a well made item otherwise and if you keep it sitting in cleaner then you will probably be fine.

I bought this Apera pH meter to test the jams pH before canning, because in home made preserves is very important to have a path lower than 4.6 to avoid growing undesired microorganisms, some of them potentially harmful as boltulism. Now, with the Apera pH meter I test before canning the pH to be safe with my jam's preserves at home, and I'm not afraid of the toxicity for my family and to share my jams with friends. Great and simple to use, just put the pH meter inside of the jam and read the number. I will buy it again for sure, and I'm thinking in buying a upgraded version in the future, because I love SAFE home preserves!

I screwed around with el-cheapo PH meters for way too long, i never realized there was such a vast difference between them. I use this for growing and before i bought this unit i was struggling with my grows, i was doing everything right but my plans seemed to stall and finished poorly in their last 3 weeks, one night it clicked that maybe it's my ph? so on a whim, i researched who made the best PH meters, and Apera was the one. I picked this unit up, and was delivered the next day. A simple check of my tap water with my old meter and this one quickly revealed that my problem was as i suspected. My PH was WAY WAY off. even calibrated, the cheapo meter was reading 1.0 higher PH in all cases. I so when i though i was at 6.5 ph, i waws at 7.5, and that just causes all sorts of nutrient uptake issues for my plants. buying this PH meter was a game changer, my plants finish perfectly now. So happy i bought this, now there are no questions in regards to PH. This is also super simple to calibrate too, it even detects the calibration liquid, really cool . money VERY well spent :)

I have gone through a dozen meters over the years. Most were OK but didn't last. Others were OK but took a long time to lock in but didn't really inspire full confidence. Others were OK but didn't fit into empty milk jugs well and that is how I mix my nutrients.This meter is the best I have used to date. It was an easy one step calibration (came spot on but I ran the process anyway) with the included solution. The meter is compact and works well with my containers. Best part is how fast and stable the readings have been. Other meters seemed to take minutes before they would stabilize but this one has a stable reading in a few seconds. Inspires great confidence and seems accurate. Combine all that with the fact the glass bulb is caged to protect it and that the probe is replaceable rounds it out.

Muy preciso y si muy fácil de usar,es el segundo que tengo de esta marca y la verdad es que para mi tanto el precio como la precisión es increíble,gracias

je recommandequalité labo, avec la fiole pour étalonnage, plus fiole pour conserver la tête de mesure.très précis, et très bien construit
