HYDROlog™ 3000PT

Test pressure and external temperature – up to 1400 bar

High accuracy hydrotest logger

The latest hydrotest logger from Aquatec…

…measuring high accuracy test pressure and ambient temperature.

The HYDROlog 3000PT instrument forms the core of the new HYDRO 3000 range of hydrotest monitoring instrumentation. It is a compact logger measuring test pressure to 1400bar and ambient temperature to depths of up to 4000m. The integral pressure sensor has ±0.05%FS accuracy and ±0.01%FS precision (to 1000bar). New features include enhanced memory and faster download. With increasingly stringent lithium battery shipping regulations, the HYDROlog 3000 overcomes potential transit issues by using standard field-replaceable batteries available across the world. Users can choose the type of battery most suitable for each deployment, whether alkaline, lithium or rechargeable.

The HYDROlog 3000PT is available in two additional models - one measuring gauge pressure, and one measuring two test pressures in a compact and efficiently designed instrument. The family of data loggers all feature the intuitive AQUAtalk software and self-contained compact design, and are compatible with the new higher speed AQUAmodem Op2 subsea optical modem.
Features
Specs

High accuracy and precision pressure

  • ±0.05%FS accuracy
  • ±0.01%FS precision (to 1000bar), ±0.05%FS precision (to 1400bar)
  • A variety of sensor options to optimise the specification – 300bar, 600bar, 1000bar, 1200bar, 1400bar

Flexible deployment

  • All instruments log data internally and have real time reporting capability as standard
  • Choose your sampling regime with continuous and burst sampling options
  • Rated to 4000m, covering typical subsea operations

Durable and robust

  • Manufactured from 316 Stainless Steel, the logger is designed for the rigours of operational use
  • All loggers are fitted with sacrificial anodes to reduce the risk of corrosion on long deployments
  • Connectors and anodes are shielded from knocks and are housed within the 60mm diameter instrument, with no protrusions for easier mounting

Designed with operational efficiency in mind

  • Deployment wizard to allow quick and easy logger set up
  • Test data outputs as an industry standard csv file and report
  • Easily transportable with alkaline and NiMH battery options
  • Faster download via the new AQUAmodem Op2 optical modem, serial cable or USB on the surface

Hassle-free maintenance

  • User-changeable standard AA size batteries available across the world – purchase locally or order direct from Aquatec
  • Service and support plans available at time of purchase or at any time during ownership

Easily integrated into your subsea equipment

  • Compact logger measuring only 60mm in diameter and 310mm in length
  • Self-contained logger that runs on internal power – external power input or external battery pack supported
  • Compatible with the AQUAdisp subsea display, AQUAmodem Op2 optical modem and AQUAswitch ROV/diver switch
  • Available in the compact and complete hydrotest monitoring skid – HYDROskid 3000

Diverse range

  • In addition to the core test pressure and temperature logger, the HYDROlog 3000 is also available as a gauge pressure logger (measuring test and ambient pressure, as well as ambient temperature) and a logger measuring 2 test pressures within one compact instrument
  • Loggers with external temperature probes to monitor dynamic temperature environments are available as custom instruments

Ready to use

  • We supply you with everything you need to get started, including software, a dummy connector, USB cable, transit case, maintenance kit, warranty and calibration certificate, and a manual.
