BPCL-GLC15/21 Gas-sensitive Photoelectric Sensing Measurement System Introduction: The BPCL-GLC15/21 gas-sensitive photoelectric sensing measurement system is primarily utilized for in-situ optical and electrical sensing measurements between gases and materials. It is equipped with a standard gas reaction chamber, featuring an interdigitated electrode (with a surface capable of attaching research materials) that allows for precise temperature control, reaching up to 400℃. The instrument is equipped with an ultra-weak light detection system and an electrochemical measurement system. At specific temperatures, it measures the optical signals (cataluminescence/thermoluminescence) from the reaction between gases and materials on the surface of the interdigitated electrode, as well as the electrical signals (R-t/i-t) from the interdigitated electrode. Additionally, it can be used in conjunction with the BPCL-GDS series gas dispensing system. The instrument finds applications in cataluminescence, thermoluminescence, cyclic luminescence, gas-sensitive photoelectric sensing, and thermoluminescence.
