The manual for Pocket Colorimeter II™ includes several parameters; can these all be measured with one instrument?
Pocket Colorimeter II™ is a single parameter instrument
Older versions of instrument manuals sometimes included other parameters that can be measured at the same wavelength as your instrument. However each Pocket Colorimeter II is calibrated to measure only one parameter. It may be possible to add a user calibration to measure one other parameter using reagents for that parameter, however it requires that the additional parameter be one of the ones in the same procedure manual, and that the range not exceed that for which the instrument is calibrated. The instrument will overrange at the upper limit given for that particular instrument. For instance, if the instrument overranges at 3.30 mg/L, a user calibration will also overrange at 3.30 mg/L.
