Certified to NSF/ANSI Standard 50 NSF is a product testing, inspection & certification organisation (Michigan, USA). Certified products are given an accuracy rating to one of three levels: L1, L2 or L3, with L1 being the highest accuracy rating. The EZ & iDip Photometers have L1 NSF certifications for a variety of test parameters; making them the ONLY meters in their class to achieve that distinction.

To carry out a test, simply:

  1. Add the water sample to the small water sample container which is on top of the photometer,
  2. Dip a reagent strip into this water sample for 10 seconds (reagents separately available, see table below),
  3. Discard the strip and read the test result on the photometer.
