A Portable Gas Analyzer With Wireless Transmission of Gas Concentrations and GPS Coordinates

A new 4-channel analyzer (one to four sensors in the unit), the Model 106, was introduced by PID Analyzers in 2005. The Analyzer consists of a readout unit that contains the processor board, 2 line by 16 character display readout, 4 channel by 16 bit ADC wit multiplixer, battery and pump. The Snap On Head contains a 4 or 5 channel amp board, a sensor board sensor caps and tubing. The amplifiers can measure nanoamps, microvolts, potentiomentric, amperometric, or fuel sensors and a Wheatstone bridge can be used for a thermal conductivity, combustible gas or infrared sensors. The user can select from more than 40 different sensors and technologies such as Photo-Ionization Detector (PID), Infrared (IR), ThermalConductivity Detector (TCD), Combustible Gas (CG), capacitance, temperature, and electrochemical sensors. This microprocessor-based analyzer calculates and displays the concentrations on its screen, and it has the capability of logging >7,000 points or automatically. The data can be downloaded to a PC via the RS232 port & the Grapher software that is provided.
