Suitable for medical gas analysis applications, a high-output emitter can be pulsed as a source of blackbody radiation for near-to-far infrared applications at 180 Hz with 50% modulation depth. The PirePlus has a high pulsing speed and maximizes signal to noise measurement, expanding the measurement dynamic range and resolution for trace gases with very low parts per million. Available in the industry standard T0-5 header package, the product is compatible with a range of detector technologies. It comes with integrated drive electronics that are voltage variable and enable users to select 1–500-Hz frequencies. Cal Sensors, Santa Rosa, CA, 707/545-4181.
