Specification :

The PCLM3 chloride meter can be used to determine chloride
concentrations in numerous types of samples. Biological samples
such as serum, plasma, urine, sweat and cerebrospinal fluid are
commonly tested. Other samples can be tested provided they are
of low ionic strength, neutral pH, have low levels of dissolved
solids, low solid matter and are free from silver halides and other
components which may react with silver.
