One-Step Calibration

Thanks to this technology the maintenance of your hydrometer is much easier than ever before. The One-Step Calibration kit is very easy to use:

  • simply place your hydrometer inside the bag and completely closed the zipper 
  • allow the calibration bag to sit for 24 to 36 hours at room temperature 
  • the hydrometer should read +/-0.3% to the RH level stated above (75%RH)
  • note the difference, if any, between the hygrometer reading and the percent HR printed at the top of this bag. This will be the umber of percentage points you'll need to add or subtract for corrected future reading.
