Apera Instruments AI314 Pocket Tester, EC60 Premium Waterproof Conductivity, Easy Switch of EC/TDS/Salinity, Replaceable BPB Sensor, 1% F.S Accuracy

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

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.
