How to Use This Calculator
  1. Select the sanitizer type: chlorine (bleach), quaternary ammonium, or iodine.
  2. Enter the concentrate strength in PPM and your target working concentration in PPM.
  3. Enter the volume of water in gallons for the sanitizer solution.
  4. The calculator shows concentrate needed in fl oz and mL, whether the target is within FDA range, min and max PPM, required contact time, and estimated cost.
  5. Mix the concentrate into water as calculated, verify concentration with test strips, then apply for the minimum contact time before rinsing.

What each input means

Sanitizer Type
Select the sanitizer type
Concentrate Strength (PPM)
PPM of the stock sanitizer solution (e.g., bleach ~52,500 PPM).
Target PPM
Desired sanitizer concentration in working solution.
Water Volume (gallons)
Volume of water for the sanitizer solution.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Sanitizer Type = 1, Concentrate Strength (PPM) = 52500, Target PPM = 100, Water Volume (gallons) = 5 = 4 input(s) provided
  2. Calculate Concentrate Needed
    Concentrate Needed
    1.28 = 1.28
  3. Calculate Within FDA Range
    Within FDA Range
    Yes = Yes
  4. Calculate Concentrate Needed
    Concentrate Needed
    37.9 = 37.9
  5. Calculate Below Minimum
    Below Minimum
    No = No
