The SafEye range of "line-of-sight" Optical Gas Detectors features a new generation of Open Path IR and UV detection systems. Open path spectroscopy offers unprecedented reliability in real-time monitoring of gaseous emissions over large areas, rendering it the accepted technology for industrial and environmental applications. 

These systems provide exceptional detection capability of gas/vapor concentrations ranging from as low as Parts Per Million (PPM) levels to Lower Explosive Limit (LEL) levels in a wide range of hazardous conditions and ambient air monitoring.

SafEye System employs a unique flash light source coupled with optical detectors and mathematical algorithms to spectrally analyze an air path ranging from 2 ft. to 450 ft. (0.6m - 140m) with high detection sensitivity in both UV and IR spectral bands. The system is compatible
with a wide range of control systems providing multiple outputs (dry contacts, 4-20mA, RS-485).

The open path line-of-sight gas detection system can monitor and transmit an alarm signal prior to occurrence of fire or an explosion, identify the chemical family concerned and activate preventative systems.

The SafEye gas detection system can serve as a process control component in the chemical and petrochemical industries, or as a safety system in commercial and industrial applications.

Typical Gas Detection Applications

The major growth of use of Open Path systems is in the area of oil and gas offshore production platforms, FPSOs and onshore production. Spectrex is particularly active with its SafEye Open Path Gas Detectors in offshore Britain (North Sea) and offshore Norway (North Sea). 

SafEye systems can be very useful in additional applications such as:

1. Combustion Monitoring - SafEye gas detector can be used to monitor combustion efficiency in various chemical processes by analyzing the ratio of combustion products such as Carbon Monoxide (CO), Carbon Dioxide (CO₂) and unburned Hydrocarbons (HC).

2. Online Process Control - SafEye Open Path gas detector can be used to monitor chemical processes by analyzing the emitted gases and relative concentrations. The system can monitor Ammonia, aromatic compounds like Benzene, Toluene and Styrene, Hydrogen Sulfide (H₂S, CS₂), Carbon Disulfide, Aliphatic Sulfides, Aliphatic Mercaptans, and many other gaseous compounds.

3. Environmental Monitoring - SafEye line of sight detectors can monitor toxic vapors or hazardous/flammable gases originating from industrial processes for the purpose of worker safety and the prevention of environmental contamination.
