GAS DETECTION 39 New range of gas sensors
DD-Scientifi c is pleased to announce the launch of its latest product designed to protect workers in hazardous environments. The new SE+CO is a highly reliable and repeatable electrochemical carbon monoxide sensor optimised for use in industrial safety applications and brings with it DD-Scientifi c’s decades of experience in providing cost effective solutions for gas detection OEMs. The sensor quickly responds to dangerous levels of carbon monoxide and is ideal for use in portable detectors deployed in oil and gas plants, mines, chemical works, steel mills and confi ned space entry.
The SE+CO is designed to be the fi rst in a new range of sensors from DD-Scientifi c and will be followed shortly by sensors optimised for other toxic gas dangers.

The PQ series is divided in to the PQN and PQD detectors, which feature an OLED display, to provide the best solution for developing industry conditions and customer demands.
PQ fi xed gas detectors offer the best solution for LEL and ppm measurements using pellistor, infrared, electrochemical sensors. These instruments offer the operator instant and up to date details of the status and ambient conditions of the targeted gas via the OLED display on the simple to use software, who can be easily adjusted. The PQD’s SH30 stainless steel sensor head enables a superb performance under harsh environmental conditions. 4-20mA and RS485 (Modbus RTU) outputs are simple to operate by connecting to Prosense gas detection panels or a suitable PLC. These detectors can operate with optional P-3R relay cards and 3 dry contact relay outputs. Alarm 1 and Alarm 2 relays are easy to set to default LEL or ppm levels. The third dry contact relay output is used for fault status.
PQ gas detectors can be safely used in potentially explosive atmospheres thanks to the ATEX certifi cation and EN 60079-29-1 performance test with the IP-65 protection class, which can be used safely in harsh outdoor conditions. With the optional P-IP66, these instruments can still withstand and operate even in the path of heavy jets of water.

Residential • Car Park Monitoring • Fire Detection Indoor Air Quality • Breath Monitoring • And More!
Euro-Gas gas sensors and circuitry offer unique features and potential advances for end product performance, ensuring cost effective, high quality solutions for detection equipment manufacturers and system installers.
Are you looking for gas sensors for new instrument development? Or a complete prebuilt and precalibrated circuit board ready to install into your own housing, with voltage, current or digital output? A wide range of gas sensing options is available for different measuring ranges and applications - from gas sensors and circuit boards to installation kits and housing.
For example, Carbon Monoxide (CO) monitoring in car parks, residential and fi re detection systems can specifi cally benefi t from our low cost two-electrode CO sensors. Guaranteed to operate continuously for over fi ve years, these sensors are a revolutionary, high performance electrochemical design. Such sensors can actually exceed lifetimes of 10 years in residential environments and are available as a single sensor or with circuitry to provide 4-20mA or digital output. Euro-Gas also offers a specifi c TÜV approved package for Carbon Monoxide detection, with conformity to VDI 2053 Standard, developed specifi cally for underground car park gas detection. This can be purchased as a circuit solution or as a complete fi xed gas detector.
For medical applications, low Hydrogen cross-sensitive CO sensor models are available for the detection of Carbon Monoxide in air. The primary application of these sensors is for breath measurement, where Hydrogen presents an issue as a cross-interferent. Our sensors are at the heart of monitoring instruments in ‘stop smoking’ programmes worldwide.
The latest Carbon Dioxide (CO2
portable and battery powered instruments. Dual beam infrared is at the core of our housed CO2 air quality monitors, including our newest traffi c light indoor environmental system.
) infrared sensors deliver speed and low power consumption at 3.5mW; ideal for industrial and
Gas sensor solutions are also available for Hydrogen, Oxygen, Hydrogen Sulphide, Nitrogen Dioxide, fl ammable and more exotic gas monitoring. New miniature digital i2c and voltage circuit boards are now optional for many of our three-electrode gas sensors.
Euro-Gas sensors and accessories suit a wide range of applications, including health & safety, air quality, HVAC, automotive, process control and more. Euro-Gas is also a worldwide specialist in personal gas detection equipment and product ranges are showcased at:
