### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great product
  

*by J***E on Reviewed in the United Arab Emirates on 10 August 2022*

Easy calibration instruction, highly recommended for salt water tank with less budget

### ⭐⭐⭐⭐⭐ 







  
  
    Mains powered with battery back up
  

*by M***X on Reviewed in the United States on 3 July 2024*

Really nice small unit that is mains powered and shows bright Ph and temp numbers on a green background.  Being mains is stays on 24/7 unlike my other monitoring unit that is only battery powered so I try to keep it off.  Use the Ph testing solutions to know how the unit reads.  Both my units monitoring read under by 0.5.Doesn't have a good way to hang it up.  Has a sticky tab that falls off from a U carriage.  Needs a couple of slots to secure it easier with zip ties or hooks.  But really like this small unit.  Quick to react to water changes immediately.  Like it.
