Description

The Orbisphere 3650/111 Portable Analyzer is a robust handheld dissolved oxygen (O₂) measurement instrument designed for field and laboratory use. It accommodates Orbisphere electrochemical oxygen sensors and offers flexible display units in ppm/ppb or ppm only, allowing precise dissolved oxygen concentration readings in liquid samples. The stainless steel construction and simple sample connection accommodate harsh industrial environments, including breweries, water treatment, and verification laboratories. Data can be stored and downloaded to a PC using the built-in RS232 connection and supplied Windows software.

Features and Benefits of 3650/111

  • Portable dissolved oxygen analyzer with flexible unit selection (ppm/ppb or ppm only) — 3650/111.
  • Rugged stainless steel instrument suitable for harsh environments.
  • Compatible with Orbisphere high-quality O₂ sensors for accurate measurements.
  • Onboard data storage for up to 500 measurements and PC download capability.
  • Simple calibration using air or known concentration standards.
  • Battery operation with long autonomy allowing field measurements without mains power.

Usage and Handling

Connect the Orbisphere 3650/111 inlet tubing to the sample point or piercing device using the instrument’s connector. Ensure the electrochemical O₂ sensor (e.g., GA2400/GA2800 series) is installed. Perform calibration in air or with known standards after membrane replacement. Use the Windows software via RS232 to download stored measurements. The device is powered by two C-type NiMH or alkaline batteries and can operate continuously for ~40 hours on a full charge. Regular maintenance and periodic calibration are recommended per manufacturer guidelines.
