Products Description
The DO9100 is a professional-grade, handheld dissolved oxygen (DO) meter designed to meet the rigorous demands of aquaculture, wastewater treatment, and laboratory research. Featuring a rugged IP67 waterproof design and advanced smart calibration technology, this device delivers rapid, high-precision readings of dissolved oxygen levels and temperature. It is the ideal tool for ensuring optimal water quality in koi ponds, fish farms, and hydroponic systems.
Key Features
High-Precision Dual Measurement:
Accurately measures Dissolved Oxygen concentration (0.0-40.0 mg/L) and Saturation (0.0-300.0%) along with Temperature (0.0-60.0°C), ensuring comprehensive water quality data.
IP67 Waterproof & Durable:
Built with a robust, waterproof housing that floats on water, making it perfect for field use in wet and harsh environments.
Smart Automatic Calibration:
Simplifies operation with automatic calibration functionality, reducing setup time and ensuring consistent accuracy.
Automatic Temperature Compensation (ATC):
Automatically adjusts for temperature variations (0-60°C) to provide accurate DO readings in fluctuating conditions.
User-Friendly Design:
Features a large, clear LCD display with backlighting for easy reading in low light. The pen-style design is lightweight (approx. 90g) and portable, powered by standard LR44 batteries.
