All-Inclusive Kit

This quaternary test paper dispenser includes everything you need to start testing your sanitizer. Each product purchased comes with a plastic dispenser, color chart, and (1) 15’ roll of test paper, which provides approximately 200 tests.

Convenient Case

Since the test papers are packaged in a plastic case, they’ll have some level of protection from water and other liquids that can cause them damage. However, they should not be stored in humid environments. Also, the case has a serrated edge that makes it easy for users to tear off a strip of the test paper. Additionally, instructions are printed on the case for the user's convenience.

Easy-to-Read Color Chart

The test paper measures concentrations between 0-500 ppm, with color matches at 0, 150, 200, 400, and 500 ppm. The distinct color match at each full unit makes it easy to detect exhaustion of solutions that should be replaced.

Quick Results

This test produces quick results. Simply tear off a small strip of the test paper, dip it into your sanitizing solution for 10 seconds, and instantly compare the resulting color with the matching chlorine color chart.

    Handy pack to have around in case the shared commercial kitchen space runs out of sanitizer strips while I'm there. You never know what to expect sharing kitchen space so this item is part of my emergency back-up supply kit, my "inspection" kit I refer to it as!
