Apera Instruments, LLC-AI314 Premium Series EC60 Waterproof Conductivity Pocket Tester Kit, ±1% F.S Accuracy, Easy Switch of EC/TDS/Salinity, Replaceable Probe

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.

I use this to measure TDS in my water, as I have a filter system for it. It was already accurately calibrated when I received it. It's well packaged, and very easy to use and read. As a HS science teacher of many years, I've had a lot of cheap crappy instrumentation devices and this one is VERY nice and well made. It comes in a very nicely molded case that will stand up to some abuse. Very good value for a well made device. Don't go on the cheap when measuring anything like this. the 1% margin is much better than higher error margins, especially for TDS filter systems. Also, stick color reading are crap. For a hot tub or pool that is probably ok, but not for anything else, like a water filter system, or for water quality studies. This would be a great addition to an environmental science dept at any school or college .

Absolutely excellent product! Easy to calibrate and stays that way. All my meters are apera!

No complaints - super fast, accurate readings. helped confirm my cheaper pen accuracy. got the ph pen as well. Love the dunno. Update: downgraded to 2 star. pen suddenly stopped working. Had started a rattling noise a couple wks after use. Discoved it was the battery compartment. Ignored it. Batteries drained and got replaced 2x. Stopped working afterwards. 🤔🤨

I have the Apera PH-20 PH meter and have been very impressed by it. I have tried cheap meters that just don't get the job done, so when looking for a Cond/TDS/ Sal. tester I gravitated to the Apera EC60. A little late for me since they have a unit that does PH as well as all the other parameters I was looking for,but since I had the PH meter already, the EC60 was the choice. Just got it today and put it to work. Once you have one of their other units it is fairly simple to learn. I performed a PPM testing on my spring veggie plants from seed, and it went like clockwork. You will pay more for their units, but you will get a unit that works well and should last a long time.

This meter was highly recommended to me by several different people. They all said that the ec60 was very accurate and easy to use, once you get the hang of it. They also said the directions were lacking and were hard to understand. I agree, the directions could be a little more detailed, but their customer service department seems to be on point, answering any emails within a day or so. Seems to be a good, well made meter. Meter is advertised as accurate to within 1%, but on my Quality certificate it's listed as 1.5% which should do for most applications. I will update review in a few months time just to keep you informed.

Works great. Easy to calibrate

Great product so long as you don't get a used product sold as new..
