review
It can be seen from the above graph that Promosolv DA2 has a low basal fluorescence value, while Topklean MC 20A has a high basal fluorescence value. Compared with the fresh bath, the fluorescence readings of the degreased bath sample A and sample B both increased , indicating that the degree of contamination was increasing. Sample B showed a much higher increase in contamination reading than Sample A, which is also consistent with what was observed with the naked eye .
The SITA pollutIon Meter can quantitatively detect the level of pollutants after the degreasing tank is cleaned, avoiding human subjective influence, so as to ensure cleaning ability of the degreasing tank. It also optimizes bath life. The qualified value of pollutants contained in the degreasing bath is defined by the cleanliness of the parts cleaned by the bath .
