Andreas Matthes: Man sollte es nur hin und wieder kalibrieren und sauber halten.
Beste ^^

A.G. LPZ: Ist okay, eigentlich in der Anwendung selbsterklärend. Knopfzelle ist enthalten, also sofort funktionstüchtig. Lieferung schnell und zuverlässig, alles gut

L&A: Für mich ist das Gerät nicht mehr aus meinem Aquarienalltag wegzudenken. Ob zur Prüfung der Wasserveränderung zwischen Wasserwechseln oder als Helfer beim Aufhärten des Osmosewassers, ich benötige und nutze es ständig. da der Leitwert immer auch abhängig von der Wassertemperatur ist, ist der automatische Temperaturausgleich des Gerätes sehr praktisch, allerdings verzögert auch das Messergebnis. Aber besser etwas warten, als einen falschen Wert abzulesen.

🔝 Magische Miesmuschel 🔝🔝 Magische Miesmuschel 🔝: 💶 Gekauft für: 23,99€

📦 Versand und Verpackung: Zügig durch Amazon in einem Karton

🔍 Lieferumfang: Das Messgerät mit Anleitung in einer Box

🛠️ An- und Verwendung: Für die Düngelösung meiner Zimmerpflanzen und die Wasserwärte im Aquarium. Immer wieder gut durchspülen, abtrocknen (abschütteln) und Schutzkappe drauf

✔️ Mir gefällt:
+ Der Preis ist ganz in Ordnung
+ Es lassen sich sowohl Leitfähigkeit als auch Temperatur bestimmen
+ Auch für meine Aquarien geeignet.
+ Die Messungen sind einigermaßen genau. Man muss Schwankungen um +/- 50µS hinnehmen
+ Lässt sich magnetisch befestigen (z.B. am Kühlschrank)

❌ Mir gefällt weniger:
- Die Messwerte sind nicht so super genau. Dafür müsste man dann aber auch mehrere hundert Euronen auf den Tisch legen. Für meinen Freizeitbedarf ist dieses Gerät also trotzdem geeignet.
- Die Anleitung ist in fragwürdigem Deutsch...

🧑‍⚖️ Gesamtbewertung: Insgesamt ein gutes Set mit vielen wichtigen Messfunktionen, ausreichend akkurat, einfach zu bedienen und zu einem ganz vernünftigen Preis.

.: Chris :..: Chris :.: Als Hobbygärtner und Aquarianer bin ich immer auf der Suche nach zuverlässigen und einfach zu bedienenden Messgeräten. In diesem Zusammenhang habe ich das HM Digital AP2 AquaPro bestellt.

Das Design des HM Digital AP2 AquaPro ist sehr einfach und funktional. Das Gerät besteht aus robustem Kunststoff und hat eine kompakte Größe, die gut in der Hand liegt. Es verfügt über ein großes LCD-Display, das die Messwerte deutlich anzeigt, sowie eine automatische Abschaltfunktion.

Das HM Digital AP2 AquaPro wird mit einer Schutzhülle geliefert, die das Gerät vor Beschädigungen schützt und es einfach zu transportieren macht.

Das Messgerät ist sehr einfach zu bedienen und verfügt über drei Tasten. Wichtig sind nur die Taste zum Ein- und Ausschalten des Geräts und eine Taste, um den angezeigten Messwert für die Lesbarkeit einzufrieren.

Die Messwerte verändern sich in Abhängigkeit zur Temperatur, trotzdem gibt es ein schnelles Ergebnis. Für mich erfüllt es seinen Zweck absolut zuverlässig und gerade als Richtwert für die Menge der Düngung ist es enorm hilfreich.

Uncertain: Screen was de-laminated on arrival, but tacky enough to reattach and has not had further issues yet.

Quality is good at price point. In the future I will only purchase sealed units, as this one may be damaged if submerged more than 1.5-2 inches.

Buttons have good responsive feedback feel, but are somewhat hard to differentiate between them by feel alone(if say measuring out of eyesight)

Overall I am very please with this unit and find it perfect for the budget conscious tester.

Ed Brown: An earlier comment suggested this was in fact a PPM meter and I can see why. Most nutrient manufacturers make EC suggestions based on millisiemen measurements, ie. 0.8 - 1.2 for seedlings, etc. This unit actually delivers the EC reading in microsiemens, ie. 800 - 1,200 for seedlings, which looks very similar to a PPM reading but it's not. If you use this under the impression it's giving you PPM numbers you are gonna be way off. The good part, micro's convert to milli's very simply. A reading on this unit of say 1,500, for example would be a standard EC reading of 1.5. A 1,250 on this unit is standard EC of 1.25 (the reading divided by 1,000).

It works great, gives the temp in C or F and came very quickly. I deducted the one star because there was no written explanation of the microsiemen vs millisiemen included with the item - which cost me an hour of research to discover. Also, the readout is smaller than I had hoped.

Paul Allee: This equipment is recommended by Lennox to test the hardness of the water. The knew that the tap water that I tested was near bottled water quality. The results of the test showed what I expected from my tap water. Though I have no way of Testing the Tester against National Bureau of Standards to see how accurate it really is.

Gordon J. Liu: I was trained as a chemist and involved in the EPA environemtal water analysis metheod validation process. For a very long time, I was searching for a easy to use but accurate device which can give me some scientific information about the tap water quality. In the past, almost all water analysis instruments are using analog devices which need constant calibration. Finally, this HM Digital, Inc manufactured a reliable portable digital conductance meter which weighs only 1.7 oz. It uses one CR-2032 lithium battery. It is using digital circuitry with fixed distance probe. It is also factory calibrated. I found it is very easy to use and the bettery will last for 2 years. It is a very reliable device to check your water purifying system. My house uses a reverse osmosis sytem under the kitchen sink. In the past, it was a quess work at best when to change those filters. Now, when I installed my new Watts filter, the specific conductance is below 20 uS/cm. Kirkland 1 L bottled water has a reading of 40 uS/cm whereas our municipal tap water has a reading exceeds 900 uS/cm which is rated as very poor quality. I love this economic yet accurate device. It is the best buy for your money!
