  • Well-priced and decent enough accuracy
Style: Regular Kit + Solution
I'm using this for my hydroponics setup, and actually have two now. They're pretty decent devices - simple to use and give me what I'm looking for. I can go .5 either way really so not too concerned about it being completely accurate, but based on a few trials I did it seems like it may be only .1 or .2 off. ... show more

  • Accurately Test Your Pool pH At Home
Style: Regular Kit + Solution
Takes the guess work out of reading color charts. Easy to calibrate and use. A little pricey but worth having for doing weekly pool water pH tests.

  • APERA REALLY WORKS!!
Style: Regular Kit+ Buffer Solution Kit
Words from the wise. IF you are purchasing apera instruments from Amazon you NEED TO BE SURE TO CHECK THE BUYER AND SELLER OF THE INSTRUMENTS YOUR BUYING FROM if it says down below SHIPS from Amazon and SOLD by Amazon your device is more than likely going to be inaccurate on readings and so fourth. I just got off the phone with APERA instruments and they stared that they ship there items to Amazon and they probably sit on Amazon's shelf for who knows how long SO IF ANY OF YOU PURCHASE THESE ITEMS BE SURE TO GO THROUGH APERAS ACTUAL WEBSITE........... these are THE FACTS!!!!!! ... show more

  • Wrong readings
Style: Regular Kit+ Buffer Solution Kit
Giving wrong readings only after a few uses. Calibrated, watched videos for troubleshooting. Still giving a ridiculously alkaline reading than it should.
