Infrared LED's can be pulsed at high frequency for optimising signal-to-noise ratio and power consumption.
Narrow bandwidth LED's eliminate the need for filters.
Evaluation Kit accepts pyroelectric, photoconductive and photovoltaic detectors.
Optional thermoelectric controller with PC control for easy evaluation of Peltier cooled emitters and detectors.
Software includes experiment programming, graphics, customed linearisation.
Water vapor concentration at low temperature
Hydrocarbon concentration from 1000ppm to 100% methane.
Carbon dioxide from 300ppm to 25%.
Two gas monitoring: carbon dioxide and methane at landfill sites.
Nitrous oxide/ carbon dioxide monitoring in greenhouses and horticultural uses.
Leak detection: petroleum and natural gas facilities.
Combustion analysis for TOC etc.
Alarm detection where interfaces with electrchemical cells invalidate their use.
This evaluation kit will operate with visible and UV optical cells.
