Hanna Portable Dissolved Oxygen Meter - HI9142

HI9142 Portable Dissolved Oxygen Meter is a robust water analysis instrument designed for accurate measurement of dissolved oxygen in laboratories, wastewater treatment, aquaculture, field environments, and industrial processes. This waterproof and portable unit utilizes a Ross and Clark polarographic method and includes a platinum cathode and silver anode, providing high accuracy for reliable oxygen determination.

The device covers a 0.0 to 19.9 mg/L (ppm) dissolved oxygen range with 0.1 mg/L resolution and ±1.5% F.S. accuracy. It features automatic temperature compensation from 0 to 50°C and can be calibrated manually in 100% DO and automatically in 0% DO. The HI9142 comes equipped with replaceable PTFE membrane caps and a simple screw cap design for fast membrane replacement and easier maintenance. Its rugged construction, waterproof housing, and supplied 4-meter polarographic probe enable demanding use in various environmental, industrial, or laboratory sites.

• 0.0–19.9 mg/L (ppm) measuring range, 0.1 mg/L resolution, ±1.5% F.S. accuracy for robust dissolved oxygen determination in water and waste samples.
• Polarographic oxygen sensor based on platinum cathode and silver anode ensures precise DO measurements in compliance with industry standards.
• Supplied with electrolyte, three PTFE membrane caps, protective shield, and rugged case for all-in-one operation and transport.
• Automatic shut-off after approx. 8 minutes conserves battery during fieldwork, and long battery life (500 hours) supports prolonged use.
• Suitable for quality control in water treatment, aquaculture tank monitoring, process water, and research laboratory applications.

Package includes HI9142 portable dissolved oxygen meter, HI76407 polarographic DO probe with 4 m cable, three PTFE membrane caps, electrolyte fill solution, protective shield, instruction manual, and rugged carrying case. Explore more water analysis and laboratory instruments at EnvMart.
