Faulty Electrode: Unreliable Results

This Industrial and Scientific electrode failed to produce accurate results despite multiple attempts. The build quality feels cheap and the readings were inconsistent, leading to incorrect measurements. The only positive aspect is the affordable price, but ultimately it is not worth sacrificing accuracy for cost..

Pros
  • High accuracy and precision in measuring pH levels.
Cons
  • Requires regular cleaning and maintenance to ensure accurate readings over time.

Accurate Electrode for Substance Analysis

This electrode is a game changer in the Industrial and Scientific field... It provides extremely accurate measurements and is easy to use. The electrode is highly recommended FOR substance analysis of any kind. Although, it may require a higher budget compared to other electrodes in the market, it`s worth the investment for the level of precision it provides..

Pros
  • Durable and long-lasting electrode
Cons
  • Requires frequent recalibration to maintain accuracy

where to start Disappointing.

Bought this model about 4 weeks ago. the first week went well. I did a three point calibration and it failed the 4.0 test. So I had to work with 7.0. I contacted Apera support and spoke to a technician. We did a factory reset and a few tests and they suggested visiting Revain. That's exactly what I did. Installed a new one, worked flawlessly for a week. I went to a weekly calibration and got an E5 error (probably a bad sensor or wrong decision in the manual). It reads fairly accurately at the…

Pros
  • pH meter
Cons
  • Crumpled
