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.
