M14Thin-Film Based Thermopile DetectorFeatures:A single-channel thin film-based thermopile offering very low noise in a compact TO-18 package with a small active area of 0.92mm x 0.4mm. This is one of the lowest noise thermopiles you can buy and provides a fast 14ms time constant with Argon encapsulation gas. Applications: Excellent for ear thermometers and handheld non-contact temperature measurement. Benefit: Small package size and very low noise with lower signal-to-noise ratio. Options:
Datasheet: For more detailed information see the datasheet (PDF). |
