Review on Sper Scientific 850051 Pen Large by Mark Lodge

Name: Sper Scientific 850051 Pen Large
Item: Sper Scientific 850051 Pen Large
Rating: 3

August 27, 2022

The resolution is 0.1 pH, not 0.01 pH.

I am giving 3 stars because although the product description says it is an "ATC 0.01 pH pen" this is incorrect as the resolution of this pen is 0.1pH. For a pH resolution of 0.01 you need the Sper part number 850052. This pen is part number 850051.

Pros

IP65 waterproof case, if accidentally dropped into the water, it will float.

Cons

There are other interesting options.
