Apera InstrumentsAI316 Premium Series PC60 5-in-1 Waterproof pH/EC (Conductivity) /TDS (ppm) /Salinity (ppt) /Temp. Multi-Parameter Pocket Tester KitCarbonfree Certified

I’ve been using the Apera PC60 for a few weeks now, and it has significantly improved my ability to manage my indoor hydroponic garden. I’m growing vegetables for my guinea pigs, and providing fresh, high-quality greens is a vital part of their diet.I chose this model because I wanted a reliable tester that could measure both EC and pH. While combining both functions into one device does create a single point of failure, I trusted Apera’s reputation for quality and accuracy. I previously used inexpensive $10–20 testers for pH and TDS, but they were inaccurate and lacked calibration support. I also prefer working with the raw EC values rather than calculated TDS, so the PC60’s direct EC readings were a big plus.Since switching to the PC60, I’ve been able to dial in both my nutrient concentration and pH with confidence. My plants are clearly doing great, and I’m optimistic about achieving higher yields. A few tips and lessons I’ve learned that might help others:• Calibration for RO Water Users: If you’re using reverse osmosis (RO) water, be sure to purchase 84 μS calibration fluid. The included 1,413 μS and 12,880 μS (12.88 mS) solutions don’t cover the low EC range of RO water. Without 84 μS fluid, my tester initially showed about 600 μS for pure RO water. After a proper three-point calibration, it correctly read near 0 μS.• pH Agitation Tip: When measuring pH, gently agitate the water by moving the tester in small circles. This helps the reading stabilize much faster—around 15 seconds compared to several minutes if left still.• Beakers Make Life Easier: Having a few small beakers makes sampling and rinsing more efficient, especially when pulling water from a larger reservoir.• Track Your Calibrations: I keep a notecard in the carrying case to record the date of my last calibration and how many times I’ve used each solution. Most calibration fluids can be reused up to five times before they should be discarded.• Proper Storage Tip: Unlike some pH meters, the PC60 probe shouldn’t be stored in 3M KCl unless it’s being stored for a long period or has dried out. For regular use, just add a few drops of clean water (distilled or tap) to the cap to keep the probe hydrated. Avoid soaking it in KCl long-term, as it may shorten the lifespan of the sensor. All in all, the Apera PC60 is a fantastic investment if you’re serious about hydroponics. It’s accurate, convenient, and far more reliable than cheaper alternatives. Highly recommended.

Was on the fence with this once because it’s a bit pricey, but I’m glad I pulled the trigger on it.Functionality, features, ease of use, and overall quality is outstanding!!Instructions were clear and easy to follow, easy to calibrate and set up for use, and the backlit screen makes it easy to read.Will need to use longer term to determine durability, but EVERY aspect of this device feels high quality and well-made.The case is nice and holds all the calibration components and gear, it has a nice pocket in the case the holds the certification and manuals… the manual itself is printed on good quality paper, is easy to understand and even comes with a laminated quick guide for basic use and calibration!!This thing wasn’t cheap but feels like great quality through and through; very happy with my purchase!

I recently ordered this Apera pc60 pen. I received it the next day, this came with a basic starter kit with solutions for 2 point calibration on both ph and conductivity (which is all I need personally, although this pen does allow for 3 point calibration) . It’s very easy to setup/calibrate once you receive it and before you use the first time. (Also this meter like many high end meters will come with a few drops in the cap, this is intentional. It doesn’t mean it was used prior, meters can’t/shouldn’t be shipped dry)the meter has some decent weight to it that’s one of the first things you’ll notice, it reads very quickly giving a smiley face when it’s complete, it functions very nicely through the different readings ph, tds, etc(after each calibration it will give a letter circled like (M), (L), (H)-it also gives temperature readings. This meter not only feels good in your hand you also looks great as well. I can’t speak about the battery life(i haven’t had long enough)or the product longevity but Apera has an excellent warranty on their products this meter comes with a 2yr warranty and 6mon warranty on the probe. Overall i think this was a good purchase on a high quality all in one meter. If anything issues problems come up, i will update. Ohh yeah never store your pens dry, be sure to follow the instructions about calibration just incase maybe you have been doing differently. It’s important that once you start the calibration (always starting with 7) that the pen is NOT shutoff before completing the entire calibration.

First Impressions...Calibration was super simple.Accuracy seems to be spot on (my RODI water measured 7.02).Being multipurpose allows me to use this with both my Aquariums and Hydroponic Systems.Great custom carrying case.I do wish the documentation was a bit more clear around re-use & replacement of calibration and storage solutions.

Very happy with the product. No more drops and comparing colors that dont clearly match any if the standards. A reliable, repeatable measurement device that is easy to use and maintain.

This is the first pH meter I have used since taking chemistry in college. The functions seemed intimidating to figure out at first, but with the tutorial video and instructions calibration and use is no problem.

Game changer for plant care, my first real chemistry tool. I’m very happy with my Apera PC60. This is my first “real” instrument for testing pH, PPM, EC, and salinity and it’s made a huge difference in how I care for my plants. Super easy to use, accurate, and the display is clear and helpful. I finally feel like I understand what’s happening in my water. Highly recommend for anyone who’s serious about plant health or just getting into the science side of growing.

This device is amazing. It does everything. Ph, TDS, salinity, EC, water temp. And the replaceable tip is what sold me. Works great so far. Highly recommend.
