Your Pooltest 9 Bluetooth is delivered with a
calibration certificate validating the performance
of the instrument as it leaves Palintest.
We recommend annual service and calibration
of all photometric instruments in normal use.
The Pooltest 9 Bluetooth also includes an
automatic routine to validate analytical performance
using certified Palintest Check Standards.Accessed
via the Mode menu, the Check Standard Mode
provides a field method of ensuring your instrument
is operating within defined specifications and also
a troubleshooting method for unexpected results.
Every Palintest Check Standards set is
supplied with certified values expressed as %T
(Transmission), derived from traceable reference
materials. Acceptable tolerances are defined on
the certificate and are automatically specified
within the Pooltest 9 Bluetooth.
