Transmission Test Procedure
TR7: Different ions react with a specific indicator to form a color or a precipitate that proportionally indicates
the concentration of the ion present by the transmission value found. A conversion chart is then used to
determine the ion concentration using the transmission value. The advantage of using transmission
measurement is that many different ions can be determined in one MENU, which expands the flexibility of
this meter. Once you have determined the %T result for the test you ran, find this %T result in the conversion
chart and read the concentration corresponding for this %T. The Micro 7+ gives the %T values as 3 digits
(example 99.2) but only the first two digits are used in the charts (round off your %T value to two digits). Tests
that can be used with the Micro 7+ in TR7 MENU are listed on page 31. Typically, the most common tests are
supplied with the conversion chart in this booklet. For conversion charts and information about the tests not
given in this booklet, visit our website. You can also use the TR7 MENU to develop your own custom
conversion chart for unusual samples to get more accurate results.
