EX-5185 PID Toxic Hydrocarbons & Organic Solvents Sensor

Sensor/Transmitter for PPM/PPB Level Detection of VOCs,
Toxic Hydrocarbons & Organic Solvents

The EX-5185 features photoionization (PID) gas sensor technology. It can be used to detect many different hydrocarbons, organic gases and some inorganic gases. This technology is suitable for detecting contaminants in air primarily because of three important factors. First, the EX-5185 PID can detect only those gases which have an IP of 10.6 eV and lower. Second, the principle constituents of clean air have ionization potentials greater than 10.6 eV; Nitrogen N2 (15.58), Oxygen O2 (12.07), Argon Ar (15.76), and Carbon dioxide CO2 (13.78). Finally, a significant number of hydrocarbons and other air contaminants of interest have ionization potentials below 10.6 eV. Examples include Benzene 9.25, Isobutylene 9.4, Toluene 8.82, Vinyl chloride 10.00 eV, etc.  In general, the greater the difference between the energy level of the PID and the IP of the gas, the bigger the response produced.
