5.6 Buffer selection (SI600 only)
There are a number of standard buffer set types that are commonly used for calibration of pH meters.
The buffer sets consist of a range of predefined pH values for which buffers are prepared in a standard
and reproducible way.
All Sentron SI line meters are compatible with the Sentron buffer set. Selected meters, such as the
SI600, have the option of changing the buffer set. The SI600 supports, besides the standard Sentron
buffer set, also DIN, NIST and JIS buffer sets. It is not possible to create a user defined buffer set.
To change the buffer set:
Go to the Calibrate menu,
now select and enter the Buffer selection
option.
Toggle and choose one of the available
buffer sets.
Confirm and apply with the Enter key, or exit
with the Back key to discard any changes.
Please see below for tables of temperature versus pH value for the various buffers.
