H2O 6-in-1 WaterPen – Comprehensive Water Quality Testing, Anywhere

The H2O 6-in-1 WaterPen is a compact, portable, and easy-to-use water quality tester designed to deliver fast, reliable results for six essential water parameters. Whether you're monitoring your home water supply, conducting environmental fieldwork, or managing industrial water systems, the WaterPen gives you instant insight into water purity at your fingertips.

Measuring Chemical Oxygen Demand (COD), Total Organic Carbon (TOC), Total Dissolved Solids (TDS), Ultraviolet Absorption (UV254), Electrical Conductivity (EC), and Temperature, this smart device provides a comprehensive snapshot of your water’s health in one simple tool.

Featuring a clear, color-coded display that instantly indicates water quality—from Poor to Excellent—along with one-button calibration and an intuitive interface, the WaterPen makes water testing accessible for everyone.

Key Features:

• 6-in-1 Multi-Parameter Tester — Measures COD, TOC, TDS, UV254, EC, and temperature for complete water analysis.

• Smart Color-Coded Scoring — Instantly shows water quality status with Red (Poor), Yellow (Fair), Green (Good), and Blue (Excellent) backlight.

• Simple Calibration — One-button calibration with distilled water ensures accuracy every time.

• User-Friendly Operation — Single-button measurement and easy-to-navigate menu for language, display, and calibration settings.

• Lightweight & Portable — Weighing only 114 g, it’s ideal for home use, fieldwork, or professional water monitoring.

Why Test These Parameters?

• COD (Chemical Oxygen Demand): Measures organic pollution by indicating oxygen needed to oxidize contaminants, helping detect water pollution levels.

• TOC (Total Organic Carbon): Indicates total organic contaminants affecting water purity, taste, and safety.

• TDS (Total Dissolved Solids): Measures dissolved minerals and salts, important for taste, health, and appliance maintenance.

• UV254 (Ultraviolet Absorption): Helps detect organic substances and microbial contamination.

• EC (Electrical Conductivity): Reflects water’s ability to conduct electricity, related to ion content and purity.

• Temperature: Critical for understanding water conditions affecting quality and aquatic life.
