Quite expensive, but worth it
I use a ph meter for plant nutrient solution. Previously, I had a couple of cheap China imports, which seemed reasonably accurate for a while, but don't last long. All ph probes degrade over time, so rather than keep buying cheap, I decided to get a more reliable one with a replaceable probe. This is quite expensive compared to some other brands with good reviews, say the Essentials PH Meter, and @ £29 the replacement probe is not much cheaper than buying a new Essentials meter. However, replacing just the probe reduces waste, and gives you options: there are 4 compatible probe types (all available on Amazon), which you can buy separately as replacements, or to measure different substances. The glass bulb is for liquids, the spear probe for solids, such as foods, soil, the flat probe for paper, cloth, skin etc. And you can buy an ORP (Oxygen Reduction Potential) probe to use with this meter, which tells you the "killing power" of your solution/water (sterilising or not, a simplification of complex subject). The life of the probe will depend on how often you use it, and how you treat it. The probe is supposed to last 12 - 24 months - it's CE rated for 6 months (for safe use), but that's NOT its life expectancy. It CAN be stored dry, without degrading it, according to instructions, but storing it dry will affect its sensitivity. So if you store it dry, for accuracy, you need to soak it in the provided solution before use. It can be stored in the soaking solution, but NOT in purified water. The kit comes with everything you need: soaking solution, 2 calibration solutions, batteries, lanyard (quite a long one), 2 containers for calibration, instruction manuals in English and German, as well as a laminated quick reference chart, all in a hard plastic case. The instructions are clear, easy to understand, and contain all relevant info. Instructions say not to use soaking/storage solutions from other companies, but as long as the same (potassium chloride or kcl @ 3 molar strength) and/or for the same type of ph meter, I don't see why. Will be ignoring that myself (no Apera replacements on Amazon, either). The calibration solutions will last quite a while, the soaking solution is enough to fill the cap to the mark about twice. 2 reviews for the replacement probe said the glass bulb was too exposed and breaks easily. I disagree - the bulb is inside and above the plastic rim, which does have gaps in the side, but doubt it would break if dropped on flat surface. IP67 means it's dust proof, and can be immersed in up to 1 m of water, or for up to 30 mins, depending on info source. It doesn't mean it's hermetically sealed, though. Overall, the meter seems robust, and looks like it will stand up well to any normal use. So far, would recommend, despite quite high price, as seems well worth it, all things considered. Edit: Have been using this for 6 years now, about once per week, and it still works fine. Have not calibrated it in a while, but it seems to be accurate enough for my purposes (fertiliser/irrigation solution for plants). Like the back-light feature, and it's very easy to calibrate. If it keeps switching to settings screen when you turn it on, it means batteries need replacing, the battery icon does not seem to show accurately. Have so far replaced mine once.

Highly accurate ph meter.
The best around for the money.I deducted a star because my example was delivered missing a sealing ring, Amazon have sent a replacement by return. After years of using cheap ones for my aquarium, and eventually loosing a batch of fish due to inaccurate readings. I have bought this , and it just performs, easily calibrated, excellent online how to videos. Upgrade your ph meter you won't regret it.

Very good but very fragile!
Really good product, 1st one arrived broken but they sent me another straight out without even wanting the broken one back. So I could just replace the sensor and have two!

useless stick to the mid priced PH pens
I not use if after i brought it for a while as did not want to calibrate it then let it sit on shelf for few weeks but now i am starting to use it. it is annoying when cal it always out buy like .03 to 0.6 never hits 7 or 4 when calibrating. and it randomly turns off and doesn't come back on for while. it not the batteries as have new ones put in and it not very good when i cant use this £75 ph pen. lesson learned i will stick to the cheaper ones at £30 they work out the box and are more accurate than this pricey one i found very disappointed but because i left it too long to start using it cannot send the broken product back and can't find the contact seller any were so if seller sees this can you contact me.

Vorweg: Das PH60 ist zu billig. Wenn man sich die meisten der negativen Rezensionen hier anschaut, weiß man, daß viele nicht in der Lage sind, mehr als einen Halbsatz in einer Bedienungsanleitung zu lesen. Für solche Leute gibt es doch Streifen- und Tröpfchentests, sie sollten dabei bleiben. Das reicht für die völlig aus. Ja, in der Abdeckkappe über der Sonde sind Feuchtigkeitsreste. Ja, das Gerät ist trotzdem neu und unbenutzt. Wie kommt's? Weil die Sonde feucht bleiben muß, wenn man sie sofort verwenden können will. Man kann die Glaselektrode auch trocken lagern, müßte sie dann aber vor der nächsten Messung 12 Stunden in Kaliumchloridlösung einweichen. Was sicher wieder etliche nicht lesen und folglich auch nicht beachten würden, nur um dann anschließend herumzuheulen, warum die Meßergebnisse nichts taugen ... Kopf -> Tisch Eine 1 vor den gegenwärtigen Preis würde das Problem vielleicht etwas lindern. Du liebe Güte. Zu meiner Bewertung: Das Gerät ist erstklassig und hochpräzise, hat aber Tücken: 1. Das Smiley im Display als Anzeige dafür, daß sich der Meßwert nun eingependelt habe, kommt zu früh. Insbesondere bei Flüssigkeiten mit einem relativ niedrigen Leitwert (unterhalb von 200 µS/cm etwa) dauert es länger, bis man ein zuverlässiges Ergebnis bekommt. Dafür kann das Gerät nichts, das sind Chemie und Physik, die das bedingen, aber für ein verfrühtes Smiley kann das Gerät dann sehrwohl. In solchen Fällen bitte Geduld mitbringen und das Smiley ignorieren, was auch mal 3 Minuten warten bedeuten kann, bis sich das Meßergebnis tatsächlich eingependelt hat. Beispiel von einer Messung heute: Der Leitwert beträgt 129 µS/cm, der pH-Wert nach 5 Minuten ist 7,92 Das Smiley kam aber schon nach 30 Sekunden bei einem angezeigten pH-Wert von 7,49. Man muß halt warten, wenn es präzise sein soll. Und genau dazu hat man das PH60 ja gekauft. 2. Damit zusammenhängend: Das Gerät schaltet zu früh ab. Das ist nicht weiter tragisch, dann muß man es, während es noch in die Meßflüssigkeit eingetaucht ist, nochmal einschalten und eben noch eine Minute länger warten. Aber ärgerlich ist es trotzdem. Leider ist diese automatische Abschaltung nicht deaktivierbar. Allgemein noch der Hinweis: Vor und nach jeder Messung, vor und nach jeder Kalibrierung, bei einer 3-Punkt-Kalibrierung auch nach jedem Zwischenschritt, dann noch bevor man das Gerät zurück in die Kaliumchloridlösung stellt sowie nachdem man es aus dieser wieder entnommen hat, bitte *immer* die Sonde mit destilliertem Wasser spülen und anschließend mit der Hand trockenschütteln/trockenschleudern. Niemals die Glas-Elektrode mit einem Tuch oder ähnlichem abwischen. Wirklich niemals. Das ruiniert die Glaselektrode. Das Gerät zeigt dann zwar noch Meßergebnisse an, das sind dann aber nur noch unbrauchbare Schätzwerte. Also Finger weg von der Elektrode. Destilliertes Wasser ist nicht im Lieferumpfang enthalten. Man sollte welches daheim haben oder hier bei amazon mitbestellen. Ich habe mir gleich einen 5-Liter-Kanister geordert, da ich es auch noch für andere Wassertests benötige. Wer sich von dem Gerät eine Zeitersparnis erhofft, ist hier falsch. Momentan sind echte Schnelltests nur mit Teststreifen und Tröpfchentest, also Indikatortests, realisierbar. Was entsprechend deutliche Verluste in puncto Genauigkeit zur Folge hat. Die oben genannten Punkte führen zu keinem Sterneabzug von mir. Wäre der Preis höher, wäre ich da pingeliger, so aber geht das trotzdem in Ordnung. Volle Punktzahl und Kaufempfehlung.

Bon produit, un peu lent a stabiliser. j'ai change pour le PC60, pour a peine plus cher qui fait la conductimetrie egalement.

I was looking for a ph meter for brewing and wanted something a little more accurate than the cheap Hanna one and all the really cheap Amazon ones. After some research I found this one. It’s exactly what I needed as it was just over $100 which was what I was looking for (trying not to get excessive and buy the Milwaukee) The accuracy is to .02 which is enough for my homebrew for sure. It worked excellent for the first brew I’ve done with it! The big thing that got this 5 stars is its an all in one kit. Comes with 3 point calibration fluids, little cups for them, and the instructions are laminated and are great. If you’re looking for a homebrew ph meter this is the one to consider for sure if you’re on a budget
