Edinburgh Sensors

Founded in 1971, Edinburgh Sensors has become one of the world’s leading manufacturers of gas sensors for cutting-edge gas sensing solutions.

The application of the company’s continued research and development has contributed to several major advances in the world of infrared gas sensing and delivered a comprehensive portfolio of products for the detection of CO, CO2 , CH4  and many other gases. Their diverse range of robust OEM Gas Sensors and Gas Detectors enable fast, reliable and continuous gas detection. With a global reputation for high performance, their gas detection products are perfect for applications where accuracy, safety and reliability are paramount.


Guardian® NG

For CO, CO2 , CH4 , N2O The Guardian NG range infrared gas monitors offer near-analyser quality, continuous sampling, measurement and display of target gas concentrations. An AC powered (100 to 240VAC) high accuracy gas monitor for CO2 and CH4 with standard ranges from 0 – 3000ppm to 0 to 100% by volume.

Guardian® NG DC

For CO, CO2 , CH4 The Guardian NG DC infrared gas monitor offers near-analyser quality continuous sampling, measurement and display of CO2 concentrations between 0 – 3000ppm by volume from low voltage DC supplies in the range of 18-30V. With tens of thousands of our monitors supporting critical processes in industries throughout the world we have an enviable reputation for reliability, accuracy, longterm stability plus low maintenance requirements. This can be attributed to our proprietary infrared sensor technology


NG For CO, CO2 , CH4 The Gascard NG infrared gas sensor is designed for ease of integration with a wide range of gas detection systems that require high quality, accurate and reliable measurement of CO, CO2 , CH4 gas concentrations. Includes real-time temperature and atmospheric pressure correction via onboard sensors, switchable 4-20/0-20mA output and true RS232 communications as standard. Options include a wired network connection (TCP/IP) for remote access and data logging over the Internet.

Chillcard® NG

For refrigerant & other common gasses The OEM Chillcard NG range of infrared gas sensors is designed for the measurement of refrigerant gases such as R125 and R134a and provides a long- term stable solution to the measurement of these and other refrigerant gases. The Chillcard NG range now includes two new gases, CO (carbon monoxide) and CO2 (carbon dioxide). The equivalent Gascard NG sensors for these gases are designed for use in air-like atmospheres and have reduced source lifetimes when exposed to high levels of hydrogen in the sample stream

Boxed Gascard®

For CO2 The Boxed Gascard provides users with access to the Gascard NG range of CO2 detection products in a convenient and robust desktop unit. Requiring only a suitable power supply and sample gas, the Boxed Gascard provides fast and reliable CO2 concentration data over a wide range of barometric pressures and environmental temperatures. It brings the accuracy and reliability of the Gascard NG gas sensors to the convenience of a desktop instrument.

Gascheck CO2  Sensors

The GasCheck is a series of low cost CO2  sensors that offer high accuracy, good long term stability, negligible cross sensitivity, small size and low power requirement. The basic GasCheck is available in three ranges 3000ppm, 3% and 10% with a 0 to 1 V non-linear output. A linearization board can be added as an option to give linear 4 to 20 mA output.


Infrared Gas Sensor The IRgaskiT® infrared gas sensor is designed for integration into a wide range of systems where fast, accurate and reliable measurement of carbon dioxide concentrations is required. The electronics module supports a range of available sensors connected via extendable cables, providing the extra flexibility required of a modern OEM instrument. The IRgaskiT® provides a temperature compensated bench with single button calibration and optional simultaneous voltage and current outputs. The sensor heads are based on a patented technique that provides true, dual wavelength infrared sensing with no moving parts.
