The only other alternative test equipment to measure CLO2 concentration that I know of, is a photometer, plus reagents. A photometer will cost you at least $200. That is what I use to measure CLO2 ppm. Reagents are consumables and need to be constantly replaced when they are used up.
If you use CLO2 test strips, you can cut them in half length-wise to double the number of strips from 50 to 100.
Jim, thanks for that link to a Canadian seller. Appears to be located in Canada. He / she is a G2C member selling on their own website. Hope it continues as it is very hard to find MMS products in Canada.
The Biotraxx product should be fine, except for the price and shipping.
