Photometer Up-Grade (9500 only)
It is now possible to upgrade the photometer with new test calibrations using
a computer. This will ensure that users can always keep the instrument up-to-
date with the latest tests. Contact YSI to request an update at
[e-mail]. No special computer software is required. Full
instructions will be supplied with the upgrade data.
Computer Controlled Operation (9500 Only)
The photometer can be controlled from a computer using suitable control
software. Such software is available from software houses or from water
treatment specialists to cover specific applications. These software programs
typically instruct the photometer to go through a predetermined series of tests
specific to that application, and then automatically receive data from the
photometer and process the test results. The internal software of the
photometer is able to receive computer commands to start new sample,
receive test program number, receive sample number and instigate
continuation test. Programmers requiring further details should contact YSI
Technical Support.
