Comment:
Use elbowed sensor-holder perches in heavily soiled tanks to prevent fibre build-up on the perch.
Installing the pH sensor in the nozzle
1)
Dismantle the sensor-holder perch then remove the nozzle from the bottom of the perch by removing its
tightening screw.
2)
Introduce a solid wire into the perch then a string.
3)
Remove the sensor's protective casing and two O-ring seals.
Henceforth, handle the sensor with care. The warranty does not cover breakage of the glass bulb.
4)
Attach the string to the end of the sensor and introduce it into the top of the perch. Use the string to pull
the sensor to the bottom of the perch.
5)
Remove the string and place the sensor in the nozzle. The sensor should protrude about twenty
centimetres.
6)
Replace only the O-ring seal nearest the glass section of the sensor.
7)
Adjust the tip of the sensor exactly flush with the end of the nozzle. Secure the sensor in place with the
tightening screw.
8)
Replace the nozzle on the perch and secure it with the tightening screw.
9)
Use the stand with a slider or another sort of system to set the perch in a vertical position. Adjust the
immersion parameters so that the nozzle always remains submerged and the submerged section is
always at least 0.50m below the surface.
10)
To prevent fibre build-up, position the sensor so that the nozzle is facing in the same direction as the
flow.
