Product presentation at the WQA 2012 show about Sensafe™ Water Metals Check. Sensafe™ Water Metals Check visual test strips are a fast, easy, accurate and inexpensive way to determine if metals are in drinking water. This patented test incorporates a unique aperture (window) indicator that develops red in the presence of +2 metals. The technology eliminates color “bleeding” and gives better results with greater sensitivity. These strips are safe and easy to use with a built in noncarcinogenic pad indicator.
