6 1/2 DIGIT MULTIMETER GAS SENSOR TESTING

The VBCC Four Probe Gas Sensor Testing Unit is a fully integrated characterization platform designed for evaluating the performance of gas sensing materials and devices under controlled temperature, vacuum, and gaseous environments. The system enables accurate measurement of sensor sensitivity, resistance variation, response time, recovery time, and long-term stability under different gas concentrations.

The testing unit consists of a stainless steel SS316 vacuum chamber with a four-probe sample mounting arrangement, precision temperature control up to 500°C, controlled atmosphere gas delivery system, vacuum pumping arrangement, and computerized data acquisition software. The system supports operation under vacuum as well as multiple gaseous environments, allowing researchers to investigate sensor behavior under real-world operating conditions.

A high-performance Source Measure Instrument (SMU) integrated with LabVIEW-based software enables precise electrical measurements and real-time monitoring of sensor characteristics. The platform is ideally suited for universities, research institutions, semiconductor laboratories, nanotechnology centers, and industrial R&D facilities engaged in gas sensor development and characterization.
