Use
The pH-sensitive element in a SI line Sentron pH probe is an ISFET semi-conductor sensor. This sensing
element needs to be driven by an electronic circuit that is built into the Sentron SI line pH meter. This
probe can only be used in combination with one of the Sentron SI line pH-meters. Any other
combination will cause erroneous measurement values and irreversible damage to both probe and
meter.
Sentron probes are robust and build to last. The pH probe nonetheless requires periodic maintenance.
Please read the Operating Tips later in the this manual to ensure your probe is properly maintained.
Do not use the probe outside the specified temperature range as this might result in probe failure or
irreversible damage to the probe.
Samples must be aqueous solutions or semi-solids and compatible with the probe’s materials.
If information is required regarding the chemical resistance of the probe, please contact your local
dealer or Sentron.
2.1 Installation
Push the probe’s connector into the socket on the upper side of the meter. The (white) notch on the
probe connector needs to be aligned with the meter, having the notch facing towards the front side of
the meter. The connector is pushed down until it clicks into the meter’s socket.
The probe can be disconnected from the meter by simply pulling the probe connector.
Connect the probe to the meter
Note:
Do not turn the probe connector once inserted into the meter’s socket. Also, make sure
both meter and probe connector are clean and free from debris before connection.
Do not pull the probe’s cable, always pull the connector.
