High Temp Thermistor EGT Sensor
Thermometrics Corporation has built thermistor probe capable of measuring temperatures up to 1000°C. This sensor can be a direct replacement for thermocouple and rtd sensors currently being used to monito exhaust gas temperatures. The types of thermistors found in a vehicle exhaust environment will typically produce a negative temperature coefficient (NTC), meaning the resistance will ...

Children with asthma affected by `safe` levels of air pollution
Children with asthma living in cities are especially vulnerable to urban pollution. Emissions from motor vehicles, in particular, are thought to provoke asthma-related symptoms. New research suggests that even 'safe' levels of atmospheric pollutants can affect children with asthma, causing breathing difficulties and an associated increase in health problems. Researchers examined the relationship ...

Continuous Monitoring of Polycyclic Aromatic Hydrocarbons using Automatic Thermal Desorption-Gas Chromatography
Polycyclic Aromatic Hydrocarbons (PAHs) are a group of over 100 different chemicals that are known to be formed typically during incomplete combustion of organic matter at high temperature. Their major sources in the atmosphere include industrial processes, vehicle exhausts, waste incinerations, and domestic heating emissions. Due to their carcinogenic/mutagenic effects, 16 PAHs are currently ...
