Worked best once when testing pH

Bought this meter last week of October, has worked well to date. When I put it in the water to test, the numbers jumped everywhere. Recalibrating was my next step, then the meter only read 0000 so I changed the batteries. However, this gauge shows 0000 when trying to recalibrate it. This is only 15 days old.

Pros
  • Best
Cons
  • too dumb

Good build quality, confused with calibration instructions

build quality is good on both, each complete with case. However, I found the calibration instructions confusing, had no idea what I was doing. My guess is that there are high, mid and low points that need to be calibrated against a known pH (3 packs). However, the instructions on how to calibrate seem unclear. I'll search the internet for more guides and look for additional packages.

Pros
  • trial year
Cons
  • negative available

You get what you pay for

I don't need a PH tester to be very accurate, just within about 0.5. I calibrated it with the packets and it consistently gave insane readings (e.g. 5.2, 6.8, 4.7) all from the same cup I wanted to test. I then calibrated it with the powder I had from my last one and it was still off. I was not satisfied with the PH tester. I didn't know it came with a PPM tester when I bought it. Works perfectly and will not be returned for this reason.

Pros
  • Slim design
Cons
  • No paint needed

At least the return was easy

First they didn't work out of the box, both devices were with dead batteries. After changing the battery, the TDS monitor EC never showed 0 at startup. Follow the instructions which weren't very good. I had to question the ppm readings. Even my distilled water was high in ppm. My tap water and filtered water from the fridge were all red no matter what. So I'm hesitant to believe this is close to being accurate. The pH monitor showed the same value of 8.1 for all the liquids I tested before and…

Pros
  • Widespread
Cons
  • No performance

It all started with coffee!

I want to buy a fully automatic espresso machine to offset the cost and waste associated with my pod maker and K-cup maker. Water was becoming a problem, so I bought a water testing kit consisting of a pH meter and a TDS meter combined with a pH standard that is soluble in water (distilled). My experience with the pH meter was not very good! Also note that I have been a laboratory scientist in my line of work for over 16 years and am very familiar with the use of glass bulb pH meters just like…

Pros
  • EXCELLENT CUSTOMER SERVICE
Cons
  • Not an automatic espresso machine
