Gas Monitors

The Guardian range of infrared gas monitors offer near-analyser quality continuous sampling, measurement and display of target gas concentrations.

These wall mounted monitors that can detect gases from sampling points up to 30 metres away, using the integral sampling system. Standard temperature and pressure compensation minimize drift.

With tens of thousands of our monitors supporting critical processes in industries throughout the world we have an enviable reputation for reliability, accuracy, long-term stability plus low maintenance requirements. This can be attributed to our infrared sensor technology and over twenty years of sensor design and manufacturing experience.

Guardian instruments are easy to install, high quality stand-alone products that require minimum set up. With ease of integration, the Guardian provides a four-digit LCD display and alarm set-point controls, housed in a tough and robust plastic IP54 rated enclosure.

The Guardian range of instruments enable fast and accurate detection / measurement of either CO2, CO, CH4 and refrigerant gases, where detection levels of between 0-1% and 0-100% by volume are required.

Indoor Air Quality (IAQ) Monitors

Indoor Air Quality (IAQ) Monitors

Monitoring and controlling indoor air quality is very important to ensure a healthy and safe living and working environment. IAQ is a comprehensive index, including room temperature, humidity, fresh air and a diverse range of low concentrations of air contaminants. The measurement of indoor air quality has, conventionally, been used for comfort control and the prevention of Sick Building Syndrome (SBS).

Edinburgh Sensors supply a variety of IAQ Monitors, Indicators and Controllers to detect CO2. These products can be used in a variety of applications such as Demand Control Ventilation, HVAC systems, residential air quality/comfort monitoring and environmental monitoring. For more information >>>
