Product Information

The MSA TRIGARD Monitoring System is designed for monitoring chlorine, sulfur dioxide and other toxic gases, as well as for oxygen deficiency or enrichment. These new monitors were designed specifically for water and wastewater facilities which are typically large producers of these gases. The MSA TRIGARD Monitor offers an affordable monitoring solution for a variety of needs.

Advanced Features
• Sensor Disconnect Under Power: MSA’s patented feature allows for sensor change-out without declassifying a hazardous area.
• Interchangeable Smart Sensors: Pre-calibrated sensor modules are ready for installation out of the box. Sensors can be replaced in the field without the use of tools. The unit quickly recognizes the new sensor type and reconfigures alarm and relay settings to optimize the new sensor.
• State-of-the-Art Display: Liquid crystal display conveniently alternates between sensor reading and gas type and features scrolling messaging, indicating ongoing diagnostic checks such as sensor "end-of-life" condition.
• World-Class Design: Engineering efforts feature a single-board design for ultimate reliability and serviceability. The mounting enclosure has been designed to be separate from the electronics and sensor, allowing for problem-free installation and servicing.
• Onboard LEDs and Relays: "Quickcheck" LEDs and four relay outputs allow for increased indication of alarm and fault conditions.“Quickcheck" LEDs, viewable from up to 50 feet, indicate NORMAL (green) and ALERT (red) status conditions. Field programmable alarm levels and normally energized/de-energized, normally opened/closed and latching/non-latching relay functions offer three levels of alarm and a fault.
