Nitrate Profi-Test

This test offers two ranges

Low range: 0.2 - 10mg/L (ppm) as nitrtate.

Medium range : 2 - 100 mg/L (ppm) as nitrate.

Clean test vial and scoop after use. Store this kit in a dry place.

Keep out of the reach of children!

Procedure for both ranges:

1) Fill test vial with 1 ml of water.

2) Add 1 level scoop of NO3-1 powder (compress this powder against the inner side of the powder container)

3) Add 1 level scoop of NO3-2 powder and swirl gently (do NOT shake) for 30 seconds.

4) Let it stand for 3 minutes.

5) Color comparison

Medium range

Place the test vial on the white part of the colour chart and compare colours looking from the TOP. Use diffuse daylight when comparing colours.

If the colour corresponds to a value lower than 10 mg/L nitrate, then it might be better to compare colours as shown for the low range (see below).

Low range

If the medium range colour comparison procedure gave a reading lower than 10 mg/L then you can use the low range procedure. This will increase the accuracy.

The colour for the low range procedure has to be compared by looking through the SIDE of the test vial. The white part of the colour chart has to be held firmly against the opposite side of the test vial. Use diffuse daylight when comparing colours.

The colour is, by looking through the side, amplified by approximately 10 fold. For this reason you have to divide the colour chart values by 10. For example 2 will become 0.2 and 50 will become 5.
