NEW Mid-infrared light-emitting diodes (MIR LED) from 2800 nm to 6500 nm for gas sensing


Mar 09 2021 Read 687 Times
nanoplus presents continuous-wave Mid-Infrared LEDs (MIR LED) at any customised wavelength between 2800 nm and 6500 nm. The devices feature continuous-wave operation at room temperature, little power consumption, and a relatively small spectral bandwidth. With these specifications, they are a broadband, incoherent and cost-effective alternative to lasers for many gas sensing applications. Portable detectors especially will benefit from their high wall-plug efficiencies. The mid-infrared LEDs are available on ceramic sub-mount or printed circuit board (PCB).
The wavelength window between 3 μm and 6 μm is a key for high-precision gas analysis based on tunable diode laser absorption spectroscopy (TDLAS). Many trace gases ubiquitous to industrial sites have their strongest absorption bands in this region. They show absorption strengths that are several orders of magnitude higher than those in other infrared areas. This concerns prevalent molecules ....

THE Cebu Provincial Government is pouring in at least P322 million worth of infrastructure and road projects in the City of Bogo and municipalities of San Remigio, Medellin, and Daanbantayan.
The majority of these projects are concreting and improvement of road sections. In a broadcast report by Sugbo News on March 1, Cebu Governor Gwendolyn Garcia said that these road projects will boost the tourism sector of these areas.
She said that proper and improved roads contribute to the opening up of economic activities in the countryside, which are aligned with the Enhanced Countryside Development program of Capitol. ....

New cost-effective IR technology offers faster accurate A2L refrigerant gas detection


Mar 01 2021 Read 1601 Times
Stationary refrigeration units, air conditioning units and heat pumps must use non-polluting refrigerant gases, with low global warming potential (GWP), in order to comply with stringent, European F-gas (fluorinated gas) regulations. These low GWP gases can be chosen from either among the natural gases such as carbon dioxide, ammonia and hydrocarbons or among the synthetic refrigerants among which are R1234yf and R1234ze olefins.
It is therefore essential to monitor for gas leaks from these systems to ensure the safety of both people and animals and to safeguard the environment. Most major hotel chains are increasingly taking into account the safety of their guests by installing gas leak detection systems both in public and meeting areas and in bedrooms where the air conditioning system and the coolers can be positioned. ....
