The 7-in-1 Water Quality Test Pen is a compact, multifunctional device designed for fast and accurate water analysis. Combining seven essential testing functions into one portable tool, it is ideal for drinking water, aquariums, swimming pools, hydroponics, and industrial applications.

This pen simultaneously measures:

• TDS (Total Dissolved Solids) – indicates mineral and contaminant levels

• EC (Electrical Conductivity) – evaluates water’s ability to conduct electricity

• Salinity – measures salt content

• pH – tests acidity or alkalinity

• Temperature – provides real-time readings

• Specific Gravity – assesses density relative to water

• ORP (Oxidation-Reduction Potential) – monitors water’s disinfection capability

•
