New PID sensor takes VOC monitoring to the next level
IGD have raised the standard for VOC detection with a brand new PID sensor! With 5 different detection range options and a range of detector heads, IGDs PID is built to perfectly suit any application.
IGDs PID proprietary UV lamp technology utilises a non-electrode lamp design. This curtails the effects of sputtering and contamination, a common issue of current PID technology.
Sputtering and contamination can affect the lifetime and accuracy of a PID, thus it is vital to negate this to ensure your PID is working at the highest quality.
IGD’s PID can last 200% longer than the market standard with their non-
electrode UV design, offering 30,000+ hours of sensor life. Ultimately, raising the bar for VOC technology, saving maintenance costs and also ensuring a high performing PID.
The common issues of humidity and temperature are massively reduced with IGDs revolutionary PID. This eliminates the possibilities of false readings and drift whilst not affecting their performance; a very important quality to ensure your life safety system is performing at its maximum capability.
All of these outstanding features are available on IGDs world leading addressable technology. More information online:

S), hydrogen (H2
The new BIOGAS 3000 fi xed gas analyser can use up to four sample ports to monitor methane (CH4 with optional monitoring of hydrogen sulphide (H2
), carbon dioxide (CO2 ) and oxygen (O2 ), ) and carbon monoxide (CO) levels. Operators can choose up to fi ve gases to
monitor. The device features easy self-installation and maintenance, and QED provides a temporary replacement unit during service, resulting in zero operational downtime for servicing. The BIOGAS 3000 system offers simple user calibration and an easy-to-operate system. The system is calibrated to ISO/IEC 17025 standards for optimum accuracy.
The BIOGAS 3000 fi xed gas analyser is available with a continuous monitoring option for CH4 , CO2 and O2 , and by incorporating external H2 S
sensors in ranges from 50ppm to 10,000ppm, it can be used to monitor before and after desulphurisation. In addition, pre-calibrated sensors that prevent system downtime are available to users as required. A built-in liquid level monitoring with dedicated alarm and moisture removal drain or the option for an automatic drain which empties the catch pot without manual intervention, offers fl exibility for on-site maintenance.
Built with an IP65-rated enclosure, the BIOGAS 3000 system is certifi ed for use in potentially explosive atmospheres (ATEX) and IECEx (IEC System for Certifi cation to Standards Relating to Equipment for Use in Explosive Atmospheres) Zone 2 areas. Various communication options are available to your SCADA system, including six confi gurable 4-20mA outputs with a Modbus RTU communication protocol. In addition, process Field Bus (PROFIBUS) and Process Field Net (PROFINET) and Ethernet communication protocols are also offered.

INIR2 and INIR4 - for leakage detection of refrigerant gases
For More Info, email: email:
Cheaper, more effi cient and the most important: more environmentally friendly - this is how we could briefl y describe the advantages of the refrigerant R32 over R410A. With a Global Warming Potential (GWP) of 675, it has a much lower environmental impact, but the impact is still negative. This is why, for us and our planet safety, early detection of even the smallest leak of R32 gas is so important.
As SGX Sensortech, we would like to introduce you our latest INIR2 and INIR4 sensors for leakage detection of refrigerant gases with low Global Warming Potential (GWP).
The INIR2 and INIR4 are user friendly digital Gas Sensors, which are designed to use the latest SGX Sensortech’s infrared technology. They are primarily designed for the purpose of the gas leakage detection in both industrial and residential environments. Designed with the latest generation of power effi cient microcontrollers allows for high fl exibility and functionality. Temperature compensation, good accuracy and simple implementation into end user system make this sensor a perfect solution for gas leakage detection.
INIR2 R32 INIR4 R32 About R32 gas
The refrigerant R32 (difl uoromethane) is used in air conditioning systems and is increasingly replacing R410A. Refrigerant manufacturers and industry organizations also recommend switching to R32 as soon as possible. Its unquestionable advantage, which has undoubtedly contributed to its rapid rise in popularity, is the substance’s very low environmental impact. The global warming potential (GWP) of R32 is almost three times lower than that of the R410A it displaces. In addition, when fi lling the equipment, the amount of agent used can be reduced by up to 30% compared to the R410A it displaces, making it signifi cantly more environmentally friendly. Thanks to this parameter, it is also possible to reduce the size of pipelines and increases the effi ciency of the entire system. Another advantage of R32 gas is its cost, which is approximately 20% lower than R410A gas.

Swiss gas sensor specialists Membrapor strive continuously to improve the selectivity of their sensors to provide even more accurate, selective and safe measurements. This year has been no exception and several enhancements have already come to fruition.
Membrapor upgraded their CH2 O/CA-10 sensor
by eliminating its cross-sensitivity to methanol. For selective measurements of formaldehyde (CH2
aqueous CH2 BIOGAS 3000™ fi xed gas analyser, a next-generation system
O) concentrations in applications with O solutions that contain methanol
as a stabiliser (“Formalin”). Such solutions are typically used for the fi xation or preservation of biological tissue and cells.
The ETO/CA-10’s cross-sensitivity to carbon monoxide (CO) has been reduced. For selective measurements of ethylene oxide (ETO) concentrations in applications where small amounts of CO, possibly due to vehicle traffi c, are present. ETO gas is widely used as a sterilisation agent for a wide range of applications.
Membrapor also launched the AsH3/C-1 and the AsH3/M-1 sensors - two extremely sensitive sensors, which enable the highly toxic gas arsine to be measured in the ppb range. They also designed a gas cap for their compact sensors (7-series). The cap can be used with Membrapor’s digital or analogue electronics as pre-calibrated units.
