Indigo® 0–400 ppm hydrogen peroxide test strips verify peroxide dosing in process and reuse water systems. Fully documented for regulatory and operational records.
Hydrogen peroxide is widely used in industrial process water and water reuse systems as an oxidizing agent to reduce organic load, control odor, and suppress microbial growth. Maintaining the correct peroxide concentration is critical to achieving treatment objectives without excessive chemical consumption.
Peroxide treatment levels in process and reuse water systems often range from 100–400 ppm, depending on system design and contamination load. Indigo® 0–400 ppm hydrogen peroxide test strips provide a rapid method to confirm active treatment levels during dosing, recirculation, and system optimization.
We've been selling hydrogen peroxide test strips since 2007. Buy fully documented Indigo® hydrogen peroxide test strips, 100 strips/pack, with a guaranteed 3 year shelf life (dated back from expiration date "yyyy.mm.dd"); see storage requirements in Specifications.
Indigo® peroxide test strips support operators by providing instrument-free verification backed by manufacturer documentation suitable for compliance reporting and operational records.
ndigo® test strips include Certificates of Analysis, SDS, Stability Statements, and Certificates of Conformance upon purchase.
Baffled by mixed units such as mL per gallon? Our Dilution Calculator can help you work it out as long as you understand a few metric equivalents to American units. e.g., 5mL is roughly a teaspoon & 4000mL is ~1 US gallon.
e.g. If you pour 2.5ml (1/2 tsp) of 35% food grade into 1 gallon (4000ml) of water, the calculator should tell you that you now have a ~220ppm solution (close enough to the 200ppm on the color chart). If the test strip reads much lower than this, your peroxide might be old. Try adding a bit more of the concentrate & retest. A 10mL graduated cyclinder could be handy for working in mL.
Got clogged sprayer nozzles? They may just need to be reamed out. We have special collection of 10 different sizes of stainless steel insect pins that can help you unclog just about any orifice, small or large.

Product is great, have ordered for a few years now BUT your shipping cost is ridiculous! We ordered peroxide test strips and the cost of shipping was close to $20.

Unfortunately all common delivery companies have had large cost increases and we are all at their mercy for shipping costs.

SERVICE IS GOOD.. While I understand availability can be tricky, resulting in a price increase, you've never been out of stock , and the price has increased. this wouldn;t bother me otherwise but.. you're the only company that sells the higher range strips. i have spent hours looking online looking for another supplier. i feel your pricing reflects the monopoly you seem to hold. i'd like to get better pricing as a we purchase them for resale. i've also ordered from you guys for 7-8 years.. i know our volume is minimal, but that's mainly because we don;t have a pile of peroxide clients. thanks

Not sure who you are comparing us to but the only "monopoly" we have is on the best prices for 5 or more & a 3 year guaranteed shelf life. Actually, we've held prices from Jan. 2019 till end of 2021 and, as you noted, we are never out of stock!

If you are using 1 strip per week, you can actually save a little bit buying 2 at a time.
Our discounts start at just 2! And it costs the same to ship 2 as 1.
Unfortunately all common delivery companies have had large cost increases and we are all at their mercy for shipping costs.
