Ceramic pressure cell

The robust ceramic pressure cell offers industry-leading accuracy and does not deform over time like membrane technology, providing long-term measurement stability.

Rugged design

Ceramic pressure cell resistant to physical force (5 x burst pressure) and enclosure made of high-quality saltwater resistant steel for use in coastal environments.

Auto compensation

Built-in microcontroller – compensates for temperature effects and applies correction values for gravitational acceleration and water density.

Vented pressure probe

Vented pressure probe, automatically compensates for changes in barometric pressure.

Simple setup

Simple setup and connection to external dataloggers using SDI-12 or 4-20 mA interfaces.
