1、 Product Description
The water quality purity testing equipment consists of a TDS test pen and a turbidity meter, forming a box that complies with the guidance standards for basic equipment allocation of national food and drug regulatory agencies. A small SCON7820 test meter is equivalent to a conductivity test pen, a TDS test pen, and a salinity test pen. Its immersive design makes field testing more flexible and convenient.
