40 Safety Gas detector is the fi rst to include a ‘push-to-talk’ feature
Combining connected gas detection and two-way radio functionality, Blackline’s G7platform provides businesses with peace of mind, helps to control costs and keep teams safe.
Rather than the usual 16 or 32 channels offered by many conventional two-way radios, G7c push-to-talk delivers up to 99 channels for communication between teams, across facilities and even between different countries (3G enabled)— all without the need for Wi-Fi or other costly infrastructure.
This detector is very reasonably priced and fi nancing plans are available to spread the costs.
G7c devices work right out of the box, automatically connecting to wireless networks in more than 100 countries. For More Info, email:

New NET3/Pl detection heads for residential, commercial and light industrial applications
The NETC3 Head from N.E.T. is an ATEX/IECEx certifi ed stainless steel enclosure complete with sensor and optional electronic transmitter, designed for application in classifi ed areas. It has been the preferred choice of many instrument manufacturers worldwide: a ready-made solution, bringing a complete sensor+electronics+housing package to be directly integrated in a gas detector or even to be used as a complete standalone fi eld device directly connected to a controller.
But for less demanding applications in residential, commercial and light industrial settings, customers have been asking for a lighter, cost-effective solution. Enters the new NET3/PL detection head from N.E.T. – an enclosure bringing you at a compact price all the benefi ts of our classic NET3 heads, including IP66 rating, front M46 thread and three possible threads at the rear (3/4”, 1” and M20).
NET10 heads are made of robust Nylon, ensuring optimal shock protection and environmental limits of -40 +60°C. The enclosures are decomposable and the sensor can be easily inspected and replaced at the end of its life time. The raw version features direct sensor output from N.E.T. comprehensive detection range: • Infrared sensors for CO2, CH4, Propane, SF6 and Refrigerant gases. • Electrochemical cells for O2
, CO, NO2 , NO, H2 S, NH3 , CL2 , SO2 .
The full Cyber version features 4…20mA output and RS485 Modbus output, along with fault and alarm contacts, over a 10-30 Vdc power supply. Full PC software and connection boards are available to perform calibrations and modify the unit’s settings.

Gas detectors for detecting explosive and combustible gases are an indispensable part of the protective equipment use by fi re brigades, disaster relief and other civil rescue teams. These devices enable helpers to establish whether an explosive atmosphere is present at the emergency location, which represents an otherwise undetectable hazard. The most accurate knowledge possible about the explosive gases and their spatial expansion is decisive for ensuring fast, safe and effi cient intervention. In the course of the MIREX project sponsored by the German Ministry of Research and Education, which ends in May 2019, InfraTec has been working on the development of an innovative device that supports a faster and more exact assessment of the danger.
The core of the innovation is a miniaturised infrared spectrometer with a tunable, micromechanical Fabry-Pérot fi lter and fast photodiode as a detector. The spectroscopic measurement technique with a spectral resolution of 30 - 40 nm in the spectral range 3.0 – 3.7 µm makes it possible to detect and quantify a wide variety of gases with just one detector element. The previous customary NDIR detectors with fi xed narrowband fi lters are normally only calibrated to one substance and do not allow for any differentiation. Due to the compact design in a TO?8 housing, insensitivity to vibrations as well as low energy consumption the spectrometer provides good preconditions for integration into an explosion?proof, portable gas detector. The MIREX project is laying the foundation to ensure that even gases with heavily overlapping spectrums such as ethane and propane can be detected later in practice by a complex analogue and digital signal evaluation.
As part of the personal protective equipment, the gas detector will be able to increase safety for rescue workers during operations in the future. For this purpose it will measure explosive and combustible gases within the range of the lower explosion limit. This limit marks the lowest concentration, in which a gas can ignite and a fl ame can spread automatically. The measurement results reach the operations centre by radio. In this way, several rescue forces can be better coordinated and monitored.
With GfG (Gesellschaft für Gerätebau mbH), the Fraunhofer Institute for Physical Measurement Technology Freiburg as well as the Institute for Fire Brigade and Rescue Technology of the Fire Brigade of the city of Dortmund, three additional partners are working alongside InfraTec, which bring their expertise to bear in this special application. In terms of perspective, the device has a far greater range of application, however. The basic operating principle can also be adapted for other purposes. The concept of similar detectors for mining, refi neries and chemical industry is highly conceivable
