PEHANON is a special pH-test strips that unifies the pH-indicator and the reference colors on one strip. Any sample color has the same effect on both, the reference colors and the reactive pad. This ensures unadulterated readings in colored solutions. The user can be sure to get accurate pH-values. pH-values can be determined without a separate color chart. Workers and machinists can use single strips instead of complete packs with color chart, which makes PEHANON highly economic. An invisible hydrophobic barrier just above the top color field prevents capillary action of the test solution beyond. The handle will remain dry and clean whatever the sample is. Therefore the use of the strip is very safe.

Indanthrene yellow paper is used to determine the end point in the conversion of vat dyes to the leuco form. In the presence of excess sodium hydrosulphite (sodium dithionite) and alkali the yellow paper turns blue. Because of the special purpose,indanthrene yellow paper is also called Hydrosulphite paper.

In domestic water supplies, iron can do great economic damage by staining laundry and porcelain fixtures and by producing an off taste in beverages. In water supplies used for commercial beverage production, low levels of iron are critical. Hach's test strips provide the most easily-used method for determining low to mid-range iron concentrations. Technicians in the field can test many samples in only a few minutes and make immediate evaluations on-site. No measuring, set-up, clean-up, or chemical handling are necessary. Hach test strips are also used in laboratories all over the world for pre-test screening-to detect the presence of materials that might interfere with lab testing. Contains 25 tests.
