Key Features

  • Electronics completely potted to eliminate corrosion in harsh, wet environments
  • Ammonia specific electrochemical sensor technology. Absolutely no false alarms
  • No more special-order guesswork or added costs for heated or stainless enclosures
  • 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 -50F to +140F
  • Accurately monitor OSHAs PEL, STEL and IDLH setpoints for personnel protection
  • Real-time continuous monitoring for early leak detection.
  • Just select the range: 0-100 ppm (standard), 0-250 ppm, 0-500 ppm or 0-1000 ppm
  • Any sensor can be field calibrated to any range listed

The GasGuard NH3 utilizes proven electrochemical sensor technology for fast and accurate leak detection. The standard detection range of the GasGuard NH3 provides real-time continuous monitoring of ammonia concentrations accurately down to 5 ppm, with no false alarms.

Every GasGuard NH3 sensor comes equipped with an intelligent internal temperature control designed to perform in the harshest of areas. The controlled environment provides optimum moisture control for extended cell life. The high-quality injection- molded polycarbonate enclosure offers excellent chemical corrosion protection and high impact resistance.

The GasGuard NH3 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 such as washdowns, defrost cycles, etc.

Applications

  • Food Processing areas
  • Cold Storage
  • Compressor Rooms
  • Tank Rooms
  • Ventilation Ducts
  • Sea Vessels
  • Refrigeration Systems
  • Perimeter Monitoring
  • Pulp and Paper
  • Heat Treatment
  • Breweries
  • Refineries
  • Chemical Plants
Benefits

  • Versatile for any application
  • Easy to order
  • Low cost
  • Simple operation
  • Rugged and reliable

The standard GasGuard NH3 sensor is designed to work anywhere, and at a lower base-model price than most of our competition. With only one electrochemical sensor for any application, designing, ordering and maintaining your ammonia detection system is less hassle. We typically recommend a 0/100 ppm range for all personnel and product protection areas. Higher ranges (0/250, 0/500, 0/1000) are an option to suit your higher alarm setpoint areas such as Engine Rooms.

From -50F blast cells, to +140F engine rooms, to chemical washdowns of processing areas, the GasGuard NH3 is prepared to survive in just about any harsh industrial condition. 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 even direct hose-hits from clean-up crews. Stainless steel enclosures are available for applications which require them.
