Description

"The top-rated pH tester on Amazon now comes with a complete calibration and probe care combo kit, including 3 bottles of 8oz pH calibration solutions (pH 7, 4 & 10), one 4oz 3M KCL storage solution, a probe cleaning brush, and Apera's unique CallBox for organizing all the solutions and efficient use of buffer solutions (help you save the cost on buffers by at least 50%). Performing pH calibration in fresh and clean calibration solutions regularly is critical to the reliable performance of pH meters. As a rule of thumb, we recommend calibrating your pH meter at least once a week. And each batch of calibration solutions should be replaced after 10-15 times of calibration. With Apera's Callbox and 8oz calibration solutions, users can perform up to 150 times of calibration. The probe cleaning brush that comes with the kit can help you easily remove contaminants on the glass bulb sensor without any damage, maximizing the life span of your pH probe.The PH20 Value pH Tester is designed for all kinds of regular water solutions pH test, including hydroponics, pools and spas, water treatment, aquariums, aquaculture, beer brewing, winemaking, cooling towers, etc. Up to 3 points of auto. calibration and 0 to 50˚C Auto temperature compensation (ATC), ±0.1 pH Accuracy with 0 to 14.0 pH measuring range; auto. recognition and auto. indication of stable readings saves you the trouble of guessing when to manually hold measurement. With a clear large screen, it supports dual display of Temp./pH value and indicators of completed calibrations (where L/M/H indicate 3 points of calibrations) and stable readings (with a smiley face). Smart self-diagnosis, warning of out-of-range measurement and incorrect calibrations. IP67 waterproof and dustproof. Up to 2000 hours' continuous operation powered by AAA batteries (with low power warning and Auto power off in 8 min if no operation). 6-Month on the the probe. "

  • Easy to use and reliably does its job.
Style: Combo Kit
I use this tool for brewing beer as well as for making and fermenting my own hot sauces, kimchi, etc. It is very easy and intuitive to calibrate and use, and extremely reliable when calibrated and used consistently. I do recommend getting the combo kit because the extras are definitely useful, but you can get away without them if you prefer. Do calibrate before each use--if only for the piece of mind--and pay attention to the manufacturer's storage recommendations, and this will serve you well for a very long time. ... show more

  • Works well
Style: Regular Kit
Used for water testing on my marijuana plants. Simple and accurate. Haven't had to recalibrate yet been about A month. Don't forget to get storage solution.

  • Spendy but good quality
Style: Regular Kit
I debated on getting one of these for a while to help make sure my plants are able to get the proper feeding. It took me a while because the cost just does not seem to justify what the item does. For something so simple I can't believe how expensive it is. Does it's job well though.

  • Works great!

Super accurate kit! Love this thing already. I was using the drop liquid kit forever and now this is a game changer. It's helped me dial in my water mixture to the exact ph balanc ei need.

  • Exactly what I expected
Style: Regular Kit
This my first time using a PH meter and it seems to work well. I'd prefer that the instruction sheet had a larger size font, as it's a bit hard to read, even for my near-sighted eyes.

  • High quality meter, with reliable and verifiable results
Style: Regular Kit
There are other, cheaper meters - and several that cost much, much more. However, for most people, this is the one you need. If you calibrate it (and that was a must for me), store it correctly (moist, but not actually in water), and give it a little TLC from time to time (soaking it in the 3M KCL fluid to restore its ionic balance), it will serve you well. I use it for my hot tub, and when calibrated weekly, it matches the Taylor kit drop test exactly - just with greater precision, and it gives you a nearly unlimited number of daily uses - which is helpful if you're adding acid to your hot tub and want to prevent any hot spotting and over dosing. BUT, one critique is that they didn't include the high pH calibration solution in the kit I purchased. If you want to reliably test over a pH of 8, you need to buy that fluid separately. (There are actually 3 total calibration fluids you need - and they only gave me 2 of them.) Still, even if you have to buy it separately, this is the best meter you can get for the price point. ... show more
