How long does a thermopile sensor last and how accurate does it remain over time? Thermopile sensors don’t have a specific life expectancy or degradation rate. As long as they are used correctly and maintained properly, thermopiles can last for years or even decades and remain in good working condition. The key is typically to just avoid damaging or contaminating the sensor surface ...
