Our TEG is designed using thermoelectric material optimized for power generation. Power is generated by maintaining a temperature difference across the TEG (seebeck effect). We incorporate high reliability construction and nickel barrier for long TEG life. The TEG can withstand temperatures up to 200°C intermittently and 150°C continuously. The Crystal H series TEM is also excellent TEG and opens up many additional models to select from. The H series is an option available on all standard TEMs.
