Optical port for pH sensors
The
Pico-pH-SUB
is compatible with special Pyro Science fiber-optic sensors for
underwater applications designated by the appendix ‘
-
SUB’ in t
he item number. An index
matching liquid inside the connector enhances the sensor signals. Before connecting a
sensor, insert a syringe needle to the bottom of the connector and fill it completely with
deionized water (Figure 4).
Alternatively and mandatory for the optical fiber with lens
(item no.
SPFIB-LNS-SUB
/
SPFIB-LNS-CL2-SUB
) for read-out of sensor spots, the optical
port should be filled with silicone oil before inserting the optical fiber. The sensor is
secured with the cap nut. Do not use a wrench. It is sufficient to tighten the nut by hand.
Optical pH sensor spots are available for different pH ranges. Please refer to the
pH
sensor manual
for more information.
