Background of development
This test allows the quick and easy determination of Formaldehyde. It comes with all necessary reagents so that the measurement
can immediately be started. Within 1 minute one gets a reliable result.
Formaldehyde is used for a large variety of products, ranging from shampoo to clothes. In large quantities it is used as raw
material in the chemical industry. Formaldehyde is poisonous and can cause allergic reactions as well as irritations of skin, eyes
and airways. If such reactions are observed after contact with suspicious substances it may be useful to control the Formaldehyde
concentration. In closed cooling or heating circuits Formaldehyde is used as biocide.
