Review on πŸ“ Accurate Atlas Scientific Calibration Solution (250mL): Achieve Precise Measurements by Chris Moody

Revainrating 4 out of 5

Easy to use stable product

I use this pH 7.0 calibration standard to test hot tubs. It's accurate and stable. When I use it I only need about 10-15ml. I pour the used part of the solution into a separate clean plastic bottle and reuse it. The price is very cheap and the delivery was fast.

Pros
  • A 250ml (8 oz) pH 7
Cons
  • Not sure
