LaMotteInsta-Test 3000 Peracetic Acid Single Factor Test Strip, 0-160ppm Range (Pack of 50)

Great ideas for a laboratory , offering great value for money and easy yo use.

I have been using these for some ClO2 solution testing -- please note Chlorine Dioxide (ClO2) is not the same as "chlorine bleach" aka sodium hypochlorite (NaClO), which is commonly used to sanitize swimming pools and drinking water -- and they work very well. I have been comparing results on these strips with a $1,000 Palintest ClordioXense meter that is highly calibrated. The meter is accurate to +/- .02ppm and has a range of .03ppm to 50ppm. The strips have been accurate (as accurate as they can be using colors) for all readings between 15ppm and 100ppm. Below 15ppm they tend to show "10ppm" if there is any chlorite in the solution (unconverted to ClO2), so I would suggest using the "Low Range" test strips which are effective, IMO between 1-10ppm.Above 100ppm the scale goes logarithmic, and it is really hard to tell 200 from 300ppm, so these will tell you that your solutions is REALL STRONG (which may be all you need) but if you need better numbers, I suggest you dilute your solution with distilled water to a 1:4 ratio so as to get it into the more useful range on the test strips. You will lose some ClO2 due to outgassing -- seems like about 5% when I do it -- but still, a much better number.My meter uses disposable sensor strips that cost about $1.00 ea, so I'll start relying on these a bit more now that I know they are pretty solid, especially for 25-100ppm measurements.

Great for verifying if sanitizer (Sanidate 5.0) is in an effective range.

I used this product for accuracy of dosage

Cool Tool

Son demasiado buenos, me han funcionado

I've used these to check the strength of my CDS. I have used them to check different batches. I know they are working as some batches have been weaker than others! I wouldn't hesitate to buy these again when I run out. Nice Seller too, checked to make sure everything was fine with my order. I hope this was helpful.

Buena calidad y hacen el trabajo muy bien.
