Description
Detect high concentrations of formaldehyde (HCHO) with the NextTeq NX157H detector tube, offering a broad 20–1,500 ppm measuring range with a detectable limit of 5 ppm using a single pump stroke. This dehumidifier tube reacts with formaldehyde to shift from yellow to pink, with results read directly off the printed scale calibrated for one pump stroke. With a TLV-TWA of 0.1 ppm and a 2-year shelf life when stored refrigerated, it's well-suited for monitoring elevated formaldehyde levels in industrial applications.
