B&C SI161 Submersible pH Sensor

The B&C Electronics SI161 submersible pH sensor is the perfect solution for pH measurements in applications where pH measurement is required in a submerged medium. This submersible pH probe comes with the SZ145 pH probe. Other probe models are available upon request.

The probe consists of:
– Electrode holder with extension for immersion measurement;
– 12 mm diameter combined pH or ORP electrode.

The electrode has a 9 meter sealed coaxial cable. This allows the electrode to be connected directly to the instrument without any extension with a coaxial cable.
The PVC holder (other materials available on request) consists of an electrode holder in which the submerged electrode is installed.
The PH or ORP electrode is protected by a guard where the SZ901 accessory can be installed for automatic cleaning of the electrode.
The electrode holder is completed with an extension tube screwed onto the top.
A movable ring is installed on the tube to regulate the immersion depth.
In case of cable extension it is possible to replace the top cover with the SZ740 connection box (IP65), which contains a suitable terminal block.
A rubber gasket with cable gripping function (diameter 2.5 mm) is mounted between the upper cap or SZ740 accessory and the extension tube to complete the probe seal.
