Thermal Sensors Low Power

Ophir Power/Energy Meters - Smart Heads - Thermal Heads - Low Power

Thermal (Thermopile) Sensors - Low Powers to 50W
Ophir has the widest selection of power sensors for low average powers in the industry. From the popular 3A series that can reliably measure down to tens of microwatts and microjoules to the L50A for up to 50W continuous. There are various shapes and sizes of sensors to fit any requirement as well as special absorbers for short pulses.
