Understanding Electrochemical Oxygen Process Analysis

Controlling oxygen levels in industrial process environments is critical across a wide range of applications. In electronics manufacturing, oxygen contamination during soldering or reflow causes oxidation that affects component reliability. In inert atmosphere processing – such as the annealing of metals or the heat treatment of precision components – even low levels of oxygen intrusion can cause surface defects and quality failures. In food processing and pharmaceutical packaging, maintaining the correct oxygen environment directly affects product shelf life and safety. 

The EC900 series uses electrochemical fuel cell technology to detect oxygen. When oxygen diffuses to the cathode of the cell, a current output is produced directly proportional to the oxygen concentration in the sample gas. Systech’s patented sensor design is unaffected by hydrocarbons or volatile atmospheres – a significant advantage in industrial environments where background gases such as wave solder flux or reflow oven atmosphere would interfere with alternative sensor technologies. 

A key advantage of the EC900 is its recovery speed. The EC913 variant is the only electrochemical fuel cell-based oxygen analyser capable of measuring ppm levels within seconds of re-exposure to ambient air, after an oxygen-free chamber has been opened for maintenance or product swaps. Alternative analysers require hours or days of nitrogen purging before they can read at ppm levels again – creating costly downtime in production environments where uptime matters. 

Typical applications include: 

• Inert atmosphere monitoring in electronics and semiconductor manufacturing 
• Metal annealing and heat treatment furnace atmosphere control 
• Wave soldering and reflow oven oxygen monitoring 
• Inert gas blanketing verification in chemical processing 
• Food processing modified atmosphere quality control
