No calibration or instructions

This PPM meter claims to have been calibrated out of the box, but I have never been able to get an accurate reading. There are also instructions on how to properly calibrate the device. Just reassuring the end user that the product is guaranteed to work…

Pros
  • Measuring range: 0-9990 ppm, 0-9990 µs/cm; Accuracy: ±2%, 0.1-80.0°C, 32.0-176.0°F; factory calibration; Automatic Temperature Compensation (ATC)
Cons
  • Blank

Pre-calibrated for pH testing

is a snap for your overall height. Yeah I mean I don't know what I was expecting for $10 honestly lol. You cannot calibrate it and it is common knowledge that they need to be adjusted from time to time. A good option for a cheap temporary tester, provided it is properly calibrated. My concern is how long will it stay correct?

Pros
  • Long battery life and low power consumption; The auto-off feature saves battery power, and our TDS meter uses less power than the HM
Cons
  • TDS meter. Knopfer Instructions

Value for money - Test, measure and verify

Because these are "cheap" pens, I bought two. Mainly because your counter never dies at an opportune time. In this case it was good that I bought two. The first showed 44.9F. Press the button to switch to Celsius scale and it will show 23.0c. Hmmm? So I change it to another one as the second device seems to be reading accurately. The instructions state that the device can be calibrated. However, they do not provide any instructions on how to perform the calibration. It also doesn't specify…

Pros
  • provides accurate and reliable test results; 3-in-1 digital TDS meter provides accurate TDS (total dissolved solids), EC (electrical conductivity) and temperature readings
Cons
  • Disappear

Good TDS for testing the filter life of your home system

I live in the country and have city water but of course a lot of agricultural chemicals get into the water here so after buying go home I immediately bought a reverse osmosis system , but the water can taste bad at times (you can tell everything when you drink very filtered water), I needed a good TDS meter to check filter life etc, it helps!

Pros
  • Test, measure and inspect
Cons
  • Big and bulky

Pre-Calibrated - Compound Analysis Instruments

When you can be confident that your $10 purchase has been properly calibrated and you're ready to throw caution to the wind throughout your grow. Yeah I mean I don't know what I was expecting for $10 honestly lol. You can't calibrate it and it's pretty common knowledge that they need to be adjusted from time to time. A good option for a cheap temporary tester, provided it is properly calibrated. My concern is how long will it stay exactly?

Pros
  • pH Test

Good for the money: Analyzers

Since these are "cheap" pens, I bought two at once. Mainly because your counter never dies at a good time. In this case it was good that I bought two. The first showed 44.9F. Press the button to switch to Celsius scale and it will show 23.0°C. Hmmm? So I change it to another one as the second device seems to be reading accurately. According to the instructions, the device can be calibrated. However, do not offer any guidance on how to perform the calibration. It is also not specified which…

Pros
  • pH meter
Cons
  • New competitors
