The Spectrex SafEye Quasar 960 NH3 is an open path UV ammonia gas detector designed for fast, reliable detection of toxic NH3 gas across a continuous line-of-sight path. Using a Xenon UV transmitter, the Quasar 960 provides long-range toxic gas monitoring from 17 to 200 ft. (5 to 60 m), with response times under 3 seconds and a sensitivity range of 0 to 500 ppm/m.
Designed for demanding industrial and hazardous environments, the SafEye Quasar 960 features heated optics to help reduce the effects of condensation and icing, high false alarm immunity, field configuration through HART or RS-485 Modbus, and multiple output options for compatibility with a wide range of control systems. The detector is not influenced by solar radiation, hydrocarbon flames, or other external infrared radiation sources, making it well suited for facilities where reliable ammonia detection is critical.
Available at Westech Industrial in BC, AB, and SK, the Spectrex SafEye Quasar 960 can be supported as part of a complete gas detection solution. Westech Industrial can assist with product selection, service support, and custom fabrication requirements for integrated safety systems, including applications where open path gas detection must be incorporated into broader facility monitoring or life safety strategies.

Description
Open Path NH3 Gas Detection
The Spectrex SafEye Quasar 960 is designed for open path detection of ammonia gas. It continuously monitors the line of sight between the transmitter and receiver. As a result, this open path NH3 detector helps identify toxic gas across wider areas. It uses UV detection technology with a Xenon UV transmitter to detect NH3 gas along the monitored path.
Long-Range Toxic Gas Monitoring
The Quasar 960 provides ammonia detection across distances from 17 to 200 ft. (5 to 60 m). The selected model determines the correct installation distance. Therefore, facilities can choose a configuration that matches their site layout. This long-range coverage supports open areas, process zones, storage areas, and facility perimeters. It also helps improve coverage where point detectors may not provide the preferred monitoring approach.
Fast Response for Critical Safety Applications
The SafEye Quasar 960 delivers a response time of less than 3 seconds. This fast response supports prompt action when ammonia gas appears along the path. Additionally, the detector offers a sensitivity range of 0 to 500 ppm/m. It also supports a minimum detectable gas volume of 35 ppm/m. Together, these capabilities help facilities monitor toxic ammonia hazards with confidence.
High False Alarm Immunity
The Quasar 960 supports reliable operation in busy industrial environments. It is not influenced by solar radiation, hydrocarbon flames, or other external infrared radiation sources. As a result, it helps reduce nuisance alarms in challenging applications. This false alarm immunity is especially important where reliability affects safety decisions and plant operations.
Heated Optics for Harsh Conditions
Heated optics help eliminate condensation and icing on the detector window. This design improves performance in environments exposed to moisture, ice, snow, or changing outdoor conditions. Furthermore, clear optics help maintain visibility across the monitored open path. This supports more dependable operation during harsh weather or demanding site conditions.
Field-Configurable Communication Options
The SafEye Quasar 960 can be field configured using HART or RS-485 Modbus communication. HART communication supports maintenance and asset management through the analog current signal. Meanwhile, the RS-485 Modbus compatible interface supports integration into computer-controlled systems. These options help facilities connect the detector to existing control and monitoring platforms.
Flexible Output Signals
The detector offers multiple output options for compatibility with different control systems. These include 0 to 20 mA current output, HART, and RS-485 Modbus. The 0 to 20 mA output communicates gas readings and key operating states. These states include normal operation, maintenance call, misalignment, obscuration, beam block, zero calibration mode, and fault conditions.
Rugged Stainless Steel Construction
The detector and source housings use stainless steel 316L with an electropolished finish. This rugged construction supports use in demanding industrial environments. In addition, conformal-coated circuit boards help protect the electronics from mechanical vibration. This durable design helps the detector maintain reliable performance over time.
Water and Dust-Tight Design
The SafEye Quasar 960 carries IP66 and IP68 ratings per EN60529 and NEMA 250 6P. These ratings help protect the detector in wet, dusty, and outdoor locations. Therefore, the unit suits facilities that require dependable gas detection in exposed industrial areas.
Certified Reliability and Performance
The Quasar 960 is SIL2 rated per IEC 61508. It also has a Mean Time Between Failures (MTBF) above 100,000 hours. Additionally, the detector is factory-calibrated and backed by a three-year warranty. These features help support long-term reliability and simplified maintenance planning.
Hazardous Area Approvals
The SafEye Quasar 960 includes hazardous area approvals for industrial gas detection applications. Available approvals include ATEX, IECEx, TR CU/EAC, INMETRO, and CSA C/US. Approval availability depends on the selected configuration. As a result, this open path NH3 detector can support a range of hazardous area requirements.
