Which way is up on the Phosphate test strip?
The pad for reading the results is the one at the bottom of the channel or well. When laid on a table with the “bump” facing up, it is the pad you can see. This [...]
Is the 0-100 peroxide test strip affected by pH?
The color scale for the 0-100 ppm peroxide strip is very dependent on the pH of the solution being tested. The test pad on the strip is buffered in the range of 5.5-6.0. The capacity [...]
Why don’t my beer pH 4.6-6.2 Test Strips work?
1) The pads on the strips are yellow when they are made. If they are not yellow then they have been exposed to heat, humidity, light, or some other detrimental condition. 2) The test strips [...]
How are the chlorine test papers affected by pH?
The 0-200 ppm chlorine test paper (145) performs best in neutral pH solutions (pH 6-8). High pH may slightly suppress the color development resulting in slightly lower results. Acidic waters do not appear to affect [...]
Precision Leak Detection Cloths & Papers
In this video, we created some example "chambers" to show how the Ammonia Leak Cloth detects ammonia gas leaks or how the Cobalt Chloride moisture detection paper can detect humidity. All of our leak detection [...]
Does the presence of hydrogen peroxide in solution impair the performance of Peracetic Acid test strips?
Peracetic acid formulations usually contain acetic acid and hydrogen peroxide to stabilize the peracetic acid. The Precision Laboratories PAA test strips have been developed to determine the peracetic acid level in the presence of acetic [...]
What is the difference between Chlor-Assure and Mid-Level Chlorine test strips?
Both the Chlor-Assure and the Mid-Level Chlorine test strips measure up to 200ppm. Both strips are complimentary to our Chlorine test Papers, although they have a slightly different chemistry. The Chlor-Assure test strips offer a [...]
Why is the Universal pH paper staining the color chart and vial?
The Universal pH test paper does undergo some sublimation over time. This is evidenced by the slight discoloration of the color chart and vial. We have found that this sublimation does not normally adversely affect [...]
