ChemCard2000™
The ChemCard2000 is an integrated fiber optic measurement system consisting of an opto-electronics interface on an ISA bus card and a software package for data acquisition and display. Any sensing method that changes its spectral characteristics in response to an analyte at the operating wavelengths of the ChemCard may be used. Prototype sensors have been developed at Research International for a number of analytes including pH, hydrogen gas, humidity, aromatic hydrocarbons, and temperature. The miniature optical pH sensor, based on pH dyes similar to those used in litmus paper, is available for industrial and biomedical applications. It operates via an immobilized indicator that is contained within a stainless steel microprobe 3.81 cm long and .033 cm in diameter.
