Great product, much more affordable than competitor prices. Quick delivery.
Thanks for noting our prices. Our discounts start at just 2 it costsÂ the same to as 1.
They work wonderfully, was so happy to finally solve my sanitizer testing problems and to use hot water is great as well.
Thanks for letting us know your experience with hot water. The chemist who designed the strips even provided us with instructions on what to expect when using hot water with quats.
Great product as always and excellent service.
Excellent product- temperature range is far more liberal and fits our needs. State surveyor recommended! Down side is cost may be a factor considering old strips are provided for free from our vendor.
If you are using old strips, be careful as they may not be accurate. We in fact guarantee ours for 3 years minimum.Â
