Apera Instruments EC60 Premium Conductivity Pocket Tester, ±1% Accuracy, Easy Switch of EC/TDS/Salinity, Replaceable BPB Sensor, ±0.5°C Temperature Sensor

The Apera Instruments EC60 Premium EC/TDS/Salinity Pocket Tester is handheld and portable kit that enables the user to test the following Electrical Conductivity measurements to an incredibly accurate degree: 1. Conductivity 2. TDS (total dissolved solids) 3. Salinity 4. Temperature The first thing you really should do if you’re thinking of picking one of these up is take a look at the product page on the Apera Instruments website. On there you’ll find videos and much more information about the product than detailed on the Amazon listing. The kit comes with everything you need to effectively test the electrical conductivity of your soil, hydroponics setup or pool. Included in the set you have two calibration solutions (4.00 and 7.00). You use the 7.00 calibration solution first, to ensure the pocket tester is calibrated to 7.00, then bring it down to 4.00 with the second calibration solution. The whole calibration process is quick and simple to do and will ensure your pocket tester returns the most accurate readings. The setup of the kit is designed to be as user-friendly as possible, giving you everything you need in a handy unbranded protective storage case. From using the pocket tester for a few weeks now I’m incredibly happy with its performance and the results. It’s so incredibly quick and easy to use and the results are incredibly accurate. I really can’t recommend the pocket meter enough for your hydroponic setup.

This is a superb bit of kit. Comes in a bland medical looking plastic box but that does a great job of keeping everything tidy. You don't get this for the looks I guess. The kit is really easy to use. It includes calibration solution so you can trust what you are seeing. Great bit of kit for keeping an eye on hydroponics. The device is well made with a backlit easy to read screen. There are plenty of videos on their website for instruction.

Works well for monitoring fertiliser solutions

Purchased for hydroponic growing. Bought a cheap meter previously which I though 'did the job', but I was getting nutrient burn far too frequently, which left me scratching my head. It was only after receiving and calibrating this item that I came to learn my old meter was under-reporting by a whopping 300ppm! The fact that it's 100% waterproof makes it easy to be very lazy taking readings; switch on the backlight, throw it in the tank, review within a minute if the thermometer takes a while to adapt (sensible compensation undertaken by the unit). Despite the probe being quite wide, there are two empty vials in the kit, making it easy to calibrate without having to waste much fluid at all. If the reservoir temperature is close to the temperature of the probe, you'll get a very accurate reading in under 30 seconds - pretty fantastic. The fact that the probe is a replaceable part gives confident this is a tool that will last a long time. Very happy customer.

It does cost a pretty good price when compared to those cheap Sub $20 TDS meter. I got an old cheap TDS meter I got from Home Depot but the old cell battery was dead and expanded. Didn't known the battery cell was bad and forced into the meter and breaks the cap and battery slot. I hate those watch battery type cells that is not as reliable as AAA size batteries. I had to get a new and better TDS meter that is more accurate and will last a long time. This Apera EC60 Tester Kit Meter can handle 4 types EC, TDS, Salinity, and of course temperature. I wanted the Apera TDS Meter but they were out of stock. For a few tens this one does 2 additional types. I have ran a few tests. Distilled Water Great Value brand = 1.00 ppm TDS R.O. System = 20 ppm TDS R.O. boiled water = 26.9 ppm TDS (Not sure why slightly higher? Maybe the container we used?) Refrigerator Water Filter = 294 ppm TDS Tap Water = 306 ppm TDS ( I think my refrigerator water filter needs to be changed or it is not working to well. Overall, I am very happy with this purchase I made. The EC60 was pre-calibrated with a tested calibrated quality certification and I was able to get a 1.0 ppm TDS on my distilled water. Other features I found out from the quick laminated guide was you can do 7 programs. Changes like option to turn off/on P1 auto lock, P2 leave 1 min default/off/on, P3 - P3 Change temp coefficient and TDS factor for calibration, P5 change salinity type measurements, P6 change temperature from F° to C°, and lastly P6 does restore back to factory default (factory resetting). This might be a little overkill for some but for me who appreciates accuracy in 1% and a high well made meter, the calibration kit, and sturdy carrying case is a perfect whole kit for testing my home water.

Na samym początku od zakupu urządzenie działało prawidłowo. Po pewnym masie musiałem je kalibrować, gdyż odczyty na buforach dawały duże rozbieżności. Niestety urządzenie nie wykrywało prawidłowych buforów i pokazywało tylko wartość dolną zakresu L czyli 84 mikro Siemensy / cm. Próba przywrócenia ustawień fabrycznych funkcją P7 - nie dawała żadnego rezultatu. Po pewnym czasie nie dało się również urządzenia wykrywać za pomocą bluetooth na telefonie. Uważam że jest to zbyt droga zabawka jak na swoją cenę - nie polecam.

very worst product. cannot possible to calibrate the instrument by given solution Don't buy it

Prodotto completamente Fallato. Fin dalle prime misurazioni funzionava a tratti. Dopo 2 settimane si accende ma i sensori misurano sempre 0. Non è il primo prodotto Apera quindi so come funzionano. La mia fregatura è che l'ho comprato ma l'ho usato qualche mese dopo quindi nessun reso. Mi sono fidato. Uno scherzetto da 140 euro. Direi che con Apera ho chiuso soprattutto calcolando le decine di alternative

... muss nicht unbedingt BlueLab sein ... Zur 1. April 2024 Situation habe ich mir zusätzlich das EC60 zugelegt, um den Nährstoffgehalt des Gießwassers zu überprüfen/anzupassen und um meine DWC richtig in den einzelnen Wachstumsphasen mit Nährstoffen zu versorgen. Das PH60 habe ich bereits seit fast 1.5 Jahren im Einsatz (Aquarium) und bin sehr zufrieden. Mit dem EC60 zusammen habe ich nun das Rundumsorglosmesspaket. - beleuchtet (John R.: Es leuchtet blau! ;D) - wasserdicht (Batteriefach mit Gummidichtung, Rest gekapselt, habe ich aber auch nie wirklich komplett unter Wasser gehalten, wozu auch) - mit 3x AAA betrieben (Knopfzellen ade, nachhaltig) - austauschbarer Sonde (nachhaltig) - langfristig genaue Ergebnisse Bei beiden Geräten sind Kalibrierlösungen dabei. Das PH60 habe ich seit dem Kauf nicht wieder kalibiriert und es zeigt weiterhin exakt die Werte der beigelegten Lösungen an. In die Schutzkappen habe ich KCL-Lösung gefüllt (gerade soviel, das die Sonde feucht gehalten wird), um die Glassonden sauber zu halten. Bei dem PH60 war ein Minifläschchen dabei, was sich schnell aufbraucht, ganz ohne beim EC60. 250ml KCL irgendwo günstig mitbestellen, der Viertelliter hält ewig. So haltet ihr eure Glassonden frisch und braucht nicht ständig kalibrieren: - aus der KCL gefüllten Kappe -> Spülen der Sonde mit Wasser (KCL Lösung entfernen) - Messung / Messungen - nach Gebrauch Spülen mit dest. Wasser - und wieder zurück in die KCL Lösung / Kappe (Bild 2) (tauscht die KCL erst, wenn die Flüssigkeit in der Kappe verbraucht ist, braucht ihr nicht nach jedem Messen tauschen, ggf. nur nachfüllen!) Die Geräte haben einen Clip, wie beim Kugelschreiber und eine kleine Öse, also klemmen und hängen möglich, es schwimmt auch an der Oberfläche, wie die BL-Geräte. Alles in allem sehr viel günstiger als von BL und ebenso gut. Letzter Hinweis: Bei manchen Growtabellen wird der EC-Wert (von 0-3) in Millisiemens pro Zentimeter (mS/cm) angegeben. Hier wird der EC-Wert in Mikrosiemens pro Zentimeter (µS/cm) angezeigt, sprich von 0-3000. Wer es hier auf die Spitze treiben und genauer als mit 0.1 (eben mit 0.001) arbeiten möchte, ist hier sehr gut bedient.
