Blocklist Based Filtering
-
Many businesses prefer to use blocklists prepared by external intelligence agencies to save the time of generating this data themselves. Also, to get as much exposure and intelligence of the threat landscape as possible. However, this blocklist information can be sent in various formats, making utilizing them a challenge. Luckily, FastNetMon is a flexible blacklisting feed filtering tool that supports a vast array of formats to receive, consume, and use blocklists from different intelligence feed providers. FastNetMon then enables you to block specific malicious and dangerous hosts using blocklist-based filtering.

Mid-Range Gas Filter Correlation CO2 Analyzer
Model T360M
-
Teledyne Advanced Pollution Instrumentation
The Model T360M CO2 analyzer measures Carbon Dioxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. Using a Gas Filter Correlation Wheel, a high-energy IR light source is alternately passed through a CO2 filled chamber and a chamber with no CO2 present. The light path then travels through the sample cell, which has a folded path of 1.28 meters.The energy loss through the sample cell is compared with the reference signal provided by the filter wheel to produce a signal proportional to concentration, with little effect from interfering gases within the sample. This design produces excellent zero and span stability and high signal to noise ratio, allowing excellent performance over a wide concentration range, making this instrument an ideal choice for CO2 reporting requirements associated with dilution CEMS.
