Port-Log System is a complete storage and publishing solution for environmental data acquired by different monitoring techniques and sensors.

Port-Log delivers environmental data from anywhere to anyone.

Port-Log allows your data to be viewed, downloaded, shared and disseminated by range of different users with varying access and security rights. Data is decoded, stored safely and provided in comprehensive web displays providing immediate and interactive access to your data.

Port-Log can be delivered as either a cloud based or installed system. Totally instrument independent, it is robust and flexible and recognises data inputs from a wide range of different sensors.

The display can be tailored to your requirements and there are several connectivity extensions available which allow data sharing to recipients unable to access the standard web pages including; remote vessels or devices, third-parties, external or internal software and applications.

• Off-the-shelf real time capability
• Cloud-Based OR installed on your own servers
• Easily share, view, disseminate and publish your data
• Easy-to-use web-based display system
• Foundation for environmental data management across your business

Port-Log.net is a quick and easy on-line storage and publishing solution for environmental data acquired by different monitoring techniques and sensors.

The ip.buffer range of smart telemetry units offer powerful and cost-effective solutions for the collection and transmissions of metocean data. The units are manufactured by leading telecommunications technology provider Scannex, and specially adapted by marine data experts OceanWise to meet the requirement of the most demanding marine environments.

“We are extremely happy with the performance of the ip.buffer. We are not aware of any other modem being able to preform to this standard”. Dr M Osborne, OceanWise.

• Smart telemetry with reliability built in
• Fail-safe and dependable
• Multi-sensor data on any device
• Delivers real-time information

Vaisala BAROCAP® Digital Barometer PTB220 is designed for measurements in a wide environmental pressure and temperature range. The barometers are ideal to be used e.g. as ship barometers, as transfer standards in weather stations and as replacements for mercury barometers.

• 500…1100 hPa or 50…1100 hPa pressure ranges
• -40…+60 °C (-40.+140 °F) operating temperature range
• Total accuracy ±0.15 hPa (class A)
• Long-term stability ±0.1hPa/yr (500…1100 hPa)
• Several output options
• Available with one, two, or three barometric pressure transducers
• NIST traceable (certificate included)

The PTB220 barometers feature extremely high accuracy. Class A barometers are fine adjusted and calibrated against a deadweight tester. Class B barometers are adjusted and calibrated using electronic working standards. All PTB220 barometers are delivered with a factory calibration certificate, which is NIST traceable.

A single barometer can have one, two or three pressure transducers. Two or three transducers provide redundancy, which improves measurement reliability in airport, weather station and pressure standard applications.

The local display has two rows and it can simultaneously show the barometric pressure, three-hour pressure trend and WMO pressure tendency code.

The PTB220 barometers use the in house developed Vaisala BAROCAP® Sensor. This silicon capacitive absolute pressure sensor has excellent hysteresis and repeatability characteristics, and outstanding temperature and long-term stability.

Vaisala BAROCAP® Digital Barometer PTB330 is a new generation barometer, designed for a wide range of high-end atmospheric pressure measurement.

• Vaisala BAROCAP® sensor
• Accurate measurement
• Excellent long-term stability
• Added reliability through redundancy
• Graphical trend display with 1-year history data
• Altitude corrected pressure (QFE, QNH)
• For professional use in meteorology, aviation, laboratories, and demanding industrial applications

The MIDAS WLR replaces the popular Model 730T as Valeport’s Water Level Recorder / Seabed Tide Gauge.

Designed for long or short term deployments in offshore environments, or locations where a traditional shore based tide gauge is impractical, the MIDAS WLR may be moored in line or to the seabed. The standard instrument is fitted with a 0.01% accuracy pressure sensor and acetal housing for up to 500m depth rating, with a deep water titanium housed option also available.

The miniTIDE is a small Tide Recorder, designed for short term underwater deployments.

Fitted with a 0.01% temperature compensated piezo-resistive cell, the miniTIDE will record high accuracy pressure data for a period of 1 month at a 10 minute sampling interval, using a single alkaline C cell. This makes it ideal for use in short term projects or for academic studies. Available with a choice of pressure ranges, and with either 500m acetal or 6000m titanuim housings.

The TideMaster is a small, cost effective Water Level Recorder, specifically designed for applications where the user requires an accurate record of water height, but with the added option of meteorological data via a ultrasonic wind speed and direction sensor.

Suitable for use in fresh or salt water, the TideMaster can be deployed for up to 1 year, dependant on the sampling rate, with instrument set up and data retrieval via an optional display panel or using the PC software supplied. Alternatively, the system can be supplied with radio modules for real time data transmission.
