Item No. 606
Formaldehyde BTI Inline
(3.5" x 1", ¾” MM NPT)

The Formaldehyde Breakthrough indicator inline is a colorimetric indicator that indicates the saturation and exhaustion of carbon absorbers and filters. The indicator is reliable and cost effect means for protection from exposure to toxic acid gases and vapors in the work place. The indicator change color from brown to blue when carbon absorbers and filters are saturated with formaldehyde vapor. Hence alerting the user to replace the exhausted carbon absorber or filter. The indicator is easily connected in-line with ¾” male, male NPT inlet and outlet. It is highly sensitive to formaldehyde vapor. It operates at temperatures -20oC to 55oC (-4oF to 131oF) and humidities 5% RH to 85%RH. The indicator is 3.5 inch tall, 1” diameter and you can observe the bright vibrant color change from all directions. The indicator has extended service life of 14 months and 1 year shelf life.
