Indigo® 0–400 ppm hydrogen peroxide test strips verify 100–400 ppm sanitation levels in water treatment, food, dairy, labs, HVAC & pools. Fully documented for inspection readiness.
Indigo® 0–400 ppm hydrogen peroxide test strips are designed to verify active sanitation and oxidation levels in the 100–400 ppm range. This range is commonly used for equipment sanitation, water treatment, hydroponic systems, HVAC water systems, pools, spas, dairy processing, beverage filling, cosmetics manufacturing, and laboratory environments. When hydrogen peroxide is used for microbial control, biofilm management, or system shock treatment, confirming proper dilution is essential for both effectiveness and cost control. Each strip delivers clear, semi-quantitative results within 30 seconds, allowing operators to confirm that peroxide levels are high enough to disinfect, yet not excessively concentrated and wasteful.
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.
Note: Some basic understanding of metric units is required.

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!

Ordered the test strips and they arrived promptly just a few days later. Great company to order from. Test strips are an easy way to maintain the correct balance of peroxide in our hot tub.

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.
