Description
Get precise, direct-reading measurements of low-level carbon monoxide concentrations with the NextTeq NX119L detector tube, calibrated for a 1–50 ppm range with a single pump stroke and a detectable limit of just 0.5 ppm. This colorimetric tube reacts with CO to shift from orange to reddish purple, allowing results to be read directly off the printed scale without the need for a separate concentration chart. With a 2-year shelf life and 10% accuracy across its range, it's well-suited for sensitive, low-concentration CO monitoring applications.
