Running a kitchen, food truck, daycare, or anywhere cleanliness is key? You gotta check your sanitizer levels – and SuperCheck test strips make it a breeze. These strips measure chlorine and bleach concentration from 0 all the way up to 750 ppm, with clear color blocks at 10 points (like 25, 50, 80, 100, 250, 340, 400, 500, 750 ppm) so you know exactly what’s in your solution. Dip for 15 seconds, match the color, and you’re done. Super handy for 3-compartment sinks, dishwashers, bars, senior homes, stores – anywhere you mix sanitizer. A few heads-ups: they won’t work on pool water, tap water, aquariums, quats, or iodine – strictly for diluted chlorine/bleach solutions. And don’t test straight bleach; dilute it first! Each bottle comes with 50 strips sealed in 5 moisture-proof packs (so they stay accurate), and you get two bottles – that’s 100 strips total. We stand by the quality, so if they ever stop working, hit us up for a replacement. Stay compliant, stay safe, and keep it clean with SuperCheck.
