Key Features
  • Sulfur Dioxide specific electrochemical sensor technology
  • Electronics completely potted to prevent corrosion in harsh environments
  • Industry standard linear 4/20 mA output
  • Corrosion, weather, and chemical resistant polycarbonate sensor enclosure
  • Intelligent-design enclosure temperature control for improved cell life
  • Sensor designed to adapt to any harsh environment from -20°F to +120°F
  • Real-time continuous monitoring for early detection of toxic concentrations
  • Accurately provide TWA, STEL and IDLH alarms for personnel protection
  • Detection range of 0-20 ppm SO2

The GG-SO2 utilizes proven electrochemical sensor technology for fast and accurate detection. The standard detection range of the GG-SO2 provides real-time continuous monitoring of concentrations accurately down to1 ppm, with no false alarms.

The intelligent internal temperature control of the GG-SO2 provides optimum temperature control for extended cell life. The high-quality injection-molded polycarbonate enclosure offers excellent chemical corrosion protection and high impact resistance.

The GG-SO2 provides an industry standard linear 4/20 mA output signal compatible with most gas detection systems and PLCs. The output signal is not affected by drastic temperature variations or other atmospheric conditions.

Applications
  • Wineries
  • Perimeter Monitoring
  • Refineries
  • Wastewater
  • Heat Treatment
  • Refrigeration systems
  • Air quality
  • Process manufacturing
  • Textiles
Benefits
  • Low cost
  • Simple Operation
  • Rugged and reliable

The standard GG-SO2 sensor is designed to work anywhere, and at a lower base-model price than most competing models. With only one electrochemical sensor for any application; designing, ordering, and maintaining your sulfur dioxide detection system is simple.

The GG-SO2 is prepared to survive in just about any harsh industrial condition, including acid washdown of processing areas. Every circuit board is sealed forever in potting compound, protecting electronic components and copper tracing from corrosion. A specially vented chemical-resistant polycarbonate enclosure protects the sensor from accidental damage, weather, and direct hose-hits from clean-up crews.

Rule of thumb for personnel protection: mount sensor no higher than breathing zone (5ft off of floor) since SO2 is heavier than air and tends to sink to low-lying areas in poorly ventilated areas. One sensor covers approximately 4000 square feet.
