Advanced infrared gas monitoring for critical industrial and commercial applications

Edinburgh Sensors, a global leader in precision gas sensing technology, announces the Guardian NG, a high performance infrared gas monitor designed to deliver continuous, accurate measurement of CO₂, CO and CH₄ across demanding operational environments.

The Guardian NG has been engineered to provide analyser grade performance while ensuring seamless integration into existing industrial and commercial control systems. Built for continuous sampling, measurement and display of target gas concentrations, the system offers flexible measurement ranges from 0–3000 ppm up to 0–100% volume, depending on gas type. This adaptability makes the Guardian NG a robust solution for applications such as controlled atmosphere monitoring, safety compliance, and environmental tracking.

The Guardian NG has a rapid T90 response time of under 30 seconds and ±2% full scale accuracy, ensuring fast, dependable readings when operational safety and quality control are paramount. Its resilient design maintains consistent performance across 0–95% non condensing relative humidity, enabling reliable operation even in challenging conditions.

Designed for easy integration, the Guardian NG offers a choice of analogue outputs 4–20 mA or 0–20 mA, alongside dual alarm relays and a dedicated fault relay for managing external devices and system interlocks. An intuitive on screen menu system streamlines configuration, while the graphical display provides clear access to historical data over user defined time periods, supporting audits, compliance requirements and performance analysis.

Housed in an IP54 rated enclosure, the Guardian NG is built for long term durability and reliability. Its fast one minute warm up time ensures systems can be operational almost immediately, supporting critical workflows in laboratories, industrial facilities, environmental monitoring setups, and more.

“Our Guardian NG reflects Edinburgh Sensors commitment to delivering reliable, high precision gas monitoring solutions that adapt effortlessly to modern industrial requirements,” said Louise Milne Edinburgh Sensors COO. “It’s combination of speed, accuracy, and robust engineering provides our customers with the confidence they need to maintain safe and efficient operations.”
