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 color chart.

Super easy to use, very clear instructions, and has a good amount of strips. I would recommend this prodcut for other food operations for sure.

These are our go to test strips. We keep them in a sealed bag by the dish machine and test daily. The health inspector was very pleased to see these as well.

Michael V. from Check Please Cafe on 12/20/2020

When your required to use something you always want it to be easy and consistent. Our numbers are always consistent with these test strips. We like the easy dispense case that makes waste less likely.

The Noble Chemichal Test Paper Dispenser is useful to have it in the workplace and employees can easily access to it and test concentrations correctly

The QT-40 Quaternary Test Paper dispenser is a quick, easy, and reliable way to get a ppm reading for your water solutions. The colors are clear and easy to read

Michael B. on 02/11/2019

This was smaller than I thought it would be so I have to not overuse it by peeling off too long a strip. The foil it was wrapped in and the plastic case helped during delivery if it had rained. The plastic case has a jagged tear strip or you can tear it by hand. On the insert it does say dip in quat solution so I have to purchase that to make sure readings are correct. Be careful when you do get your test strips and see if you need quat or if you can use bleach water to test.

These Noble test strips making the testing process super easy. They've been successful in appeasing the local health department and give us an accurate read on our sanitizing solution.

Philip S. on 12/09/2018

Great test paper for our sanitizer solution, it really takes the guess work out of my managing of employees. Now i can come behind the employees and ensure my chemicals are diluted correctly. The health department loves to see these. They are the most beneficial for me to be able to come behind new employees and ensure that they are using the chemicals correctly.

Michael K. from Husam Shabaneh on 08/10/2018

These test strip are incredible they take the guess work out of marking sure thing are clean. It is way read and the price is great.

Joel P. from Padilla on 11/16/2017

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!

Christopher M. from The Savage Patch on 08/14/2017

Wow the squads tester strips are really nice I'm impressed it was very easy to use very easy to Rees read comparison chart you simply dip it into your sanitizer well you rip off a piece that's about as long as you wanted to be instead of just going with whatever size strips they cut you rip off how much you need to step it in your sanitizer and bing bang boom you're done

Mike R. from N/A on 06/01/2017
