The new Teledyne Valeport pH
sensor developed in
collaboration with ANB Sensors,
introduces a cutting-edge, self-
calibrating solution for robust,
reliable pH measurements in
ocean monitoring. This
innovative sensor redefines how
pH is measured over extended
periods of time, offering a
powerful alternative to
traditional glass electrode
technology.
Traditionally, pH measurements
have used glass electrode
technology. While highly
accurate, this method requires
frequent instrument calibration
to prevent reference electrode
drift, resulting in lengthy sensor
downtime. Glass electrodes are
also more fragile and require
storage in very specific
conditions.
Unlike conventional pH sensors,
the new Teledyne Valeport pH
leverages Teledyne Valeport’s
respected engineering
expertise and ANB’s patented
calibration-free technology to
Teledyne Valeport
pH sensor
SELF-CALIBRATING PH SENSOR
create a leading pH sensor.
This advanced sensor is self-
calibrating, preventing
instrument downtime, reducing
calibration-related costs, and
significantly extending
deployment periods. The sensor
is also highly durable and easy to
store, making it a resilient and
superior alternative to traditional
pH sensors.
Engineered for versatility, the
sensor is rated to depths of up
to 1250m and delivers
exceptional accuracy of ±0.1 pH.
Its rugged titanium housing
ensures reliability in harsh marine
environments, making it suitable
for a wide range of applications,
including: fixed site monitoring,
buoys and frames, ROVs, AUVs
and ASVs.
What sets the Teledyne Valeport
pH sensor apart is its
combination of simple
operation, robustness, and ease
of handling and storage. It is
particularly well-suited for long-
term deployment scenarios due
to several unique features:
●
Robust solid-state
technology - for durability in
extreme marine conditions
●
Reference drift
compensation - to maintain
accuracy over time
●
Calibration-free
operation - in situ self-calibration
eliminates the need for frequent
recalibrations
●
Bio foul solution - a low
concentration of biocide is
produced at the sensor head to
keep the transducer clean and
ensure reliable data collection
●
More responsive
temperature compensation -
improving measurement accuracy
in varying ocean conditions
Designed with practicality in
mind, the Teledyne Valeport pH
sensor features Valeport’s
signature titanium housing and
measures 204mm in length with a
diameter of 47mm. It operates on
9-28V DC power with a
consumption of <32 mA @12 V
DC and weighs less than 1 kg in
air.
