Comparisons Of Water Analysis Kits

Hellige Water Testing Outfits and a La Motte TRL-05 Water Testing Kit were evaluated by comparison with standard analytical methods. The testing outfits and kit often gave values for variables which were 80-120 percent of values obtained by standard methods. However, for some variables, and especially for total ammonia nitrogen, the testing outfits and kit did not provide reliable data for all concentrations. Results of the present study and earlier studies are summarized in tabular form to provide an assessment of the reliability of seven water testing systems.
