EC DEMO test board

DataSheet Download

SemeaTech EC DEMO BOARD is a general testing module specifically designed for SemeaTech electrochemical gas sensors, which was developed to meet a wide range of sensor evaluation and testing demands. Once sensors are connected to the board, the SIG pin outputs a voltage signal corresponding to the sensor's operating status. By monitoring this voltage signal, users can observe the sensors' performance in real time. When sensors detect different concentrations of target gases, the output voltage on SIG pin changes accordingly. This board can be used to verify sensor functionality, determine whether sensors are damaged and ensure that sensors are operating properly and not affected by circuit-level issues.
EC DEMO BOARD is compatible with SemeaTech's 3-Series, 4-Series, 7-Series, and mini-Series electrochemical sensors.
