Disappointing Performance of Substance Analysis Instrumentation

After trying this Industrial and Scientific tool I regret purchasing this item.While the price seemed justifiable, the calibration of the equipment was off, resulting in inaccurate readings. The only positive note was the ease of use, but unfortunately, this did not outweigh the cons. Overall, I am extremely disappointed with this product and cannot recommend it to other buyers..

Pros
  • Easy, accurate, and consistent calibration of Hach MiniLab equipment.
Cons
  • Expensive investment for small lab operations.

Works perfectly! Not as fragile as these other pH testers.

Works great! It's not as fragile as the other ph testers with a very thin wire that breaks if you accidentally tap it lightly on something.

Pros
  • One point calibration on model H130 (recommended range: 5.0 to 9.0 pH)
Cons
  • Big and bulky
