HMS M-Series
HMS M-Series
The HMS M-Series are single thermopile sensors in small TO-46 packages with lens optics. They are designed for non-contact, short distance temperature measurements. Two different lens optics are available. In combination with the different thermopile chip sizes, a FOV between 12° and 28° is possible. The sensors are also available as modules with an integrated analog or digital signal conditioning unit for an easier application.
