Ammonia N°1 will only dissolve completely after adding Ammonia N°2.
Samples with concentrations above 2 mg/l urea may lead to results in between the
measurement range. If so, please dilute sample with urea-free water and re-do the test.
Ammonia and chloramines will be detected together. The result displayed will show the sum of
both.
The temperature of the water sample must be between 20 °C and 30 °C to ensure precise
measurements.
Test needs to be carried out not later than 1 hour after taking the sample.
If seawater is tested, the sample needs to be pre-treated with special conditioning powder
before Ammonia N°1 is added.
Do not store PL Urea 1 below 10 °C as it might granulate.
PL Urea 2 needs to be stored between 4 °C and 8 °C.
