Overview

The HYDROlog® 3000PPT is a compact, self-contained subsea logger with integrated sensors for dual test pressure and ambient temperature monitoring. Designed for hydrotest and subsea pressure monitoring applications, it combines measurement, internal logging, battery power and live data access in a standalone instrument.

Rated for deployment to 4,000 m, the HYDROlog® 3000PPT measures two test pressures up to 1,400 bar (20 kpsi) and ambient temperature with ±0.1 °C accuracy. Data is stored internally, with live readings available through compatible cabled, optical modem or subsea display interfaces. Data download is supported while logging continues.

Flexible burst or continuous sampling allows the logging regime to be configured to meet monitoring requirements, while field-replaceable AA batteries, external battery pack compatibility and stainless steel or titanium construction support demanding offshore and subsea deployments.
