HM COM-360 DUAL Sensor pH/EC/TDS/Temp. Meter
The HM COM-360 is a professional-grade waterproof meter designed for comprehensive water quality analysis. This advanced handheld device accurately measures Potential Hydrogen (pH), Electrical Conductivity (EC), Total Dissolved Solids (TDS), and Temperature, making it an indispensable tool for a wide array of applications.
Key Features
The COM-360 is packed with features to ensure precise, user-friendly, and reliable performance:
• Multi-Parameter Measurement: Measures pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), and Temperature simultaneously.
• Five Scales: Features pH, µS (microsiemens), mS (millisiemens), ppm 0.5 (NaCl) Scale, and 0.7 (442™) Scale for versatile readings.
• Automatic Temperature Compensation (ATC): Utilises three temperature coefficients for accurate readings regardless of water temperature, with an ATC range of 1-50°C.
• Digital Calibration: Allows for push-button digital calibration to any point within the meter’s range. pH calibration supports 4, 7, or 10 pH for fine-tuning.
• Water-Resistant Housing: Designed with a water-resistant (splash-proof) housing for durability in various environments.
• User-Friendly Display: Features a large, easy-to-read LCD screen that includes simultaneous temperature readings.
• Replaceable Sensor: Equipped with a replaceable sensor (model SP-CP) for extended product life. The probe is a detachable pH and TDS/EC sensor.
• Factory Calibrated: Comes factory-calibrated for pH, EC, and TDS.
• Convenience Functions: Includes an auto-off function after 5 minutes, a data-hold function, and a low-battery indicator.
• Complete Kit: Supplied with a translucent cap, 2 (AAA) alkaline batteries, pH 4 & 7 calibration solutions, pH storage solution, and a lanyard.
Applications
The COM-360 is a versatile instrument suitable for a broad range of water quality testing needs, including:
• Water Quality Testing: General assessment of water purity.
• Hydroponics & Gardening: Monitoring nutrient solutions for optimal plant growth.
• Water Purification: Checking the effectiveness of water treatment systems.
• Wastewater Regulation: Ensuring compliance with environmental standards.
• Aquaculture: Maintaining healthy aquatic environments.
• Colloidal Silver Production: Essential for accurate concentration measurements.
• Labs & Scientific Testing: Reliable for various laboratory and scientific experiments.
• Pools & Spas: Balancing water chemistry for safety and enjoyment.
• Ecology Testing: Assessing environmental water conditions.
• Boilers & Cooling Towers: Preventing scale build-up and corrosion.
• Water Treatment: General monitoring in water treatment processes.
