EXPANSIONS & CUSTOMIZATION
The PU[REC] data logger is available as a 50 kS/s or 200 kS/s option. In addition to that, you can extend your PU[REC] with a high-speed CAN interface and customize it with a wide range of analog input channels (MSI) as well as with quasi-static channel expansion modules.

OXYGEN Measurement Software
Use the full potential of the PU[REC] with the pre-installed and easy-to-use OXYGEN measurement software. It supports you with a huge amount of software features but still is very intuitive to use.
One of the core features of OXYGEN is powerful data recording. All the acquired data can be stored in one file with a simple touch on the record button. You can achieve data rates up to 1 GB/s and don’t have to bother to lose anything.
- Simple recording and storing of data
- Review your data during recording with DejaView
- Various trigger conditions and powerful trigger actions
- Time-based & event-based file-split options
- Channel-specific storing options for waveform and statistics data recording
- Easy report and export features

SOFTWARE OPTIONS
Our powerful measurement software OXYGEN has a huge number of standard features already included such as FFT analysis, visualization, analysis of post-processing, trigger and events, math and calculations, export possibilities, reporting options and many more. If you need more than this, you can also make use of our optional software options:
OXYGEN-NET
Connect all your DEWETRON measuring devices with OXYGEN-NET to form a virtual measuring device. This allows you to measure absolutely synchronously using more than one measuring device, even at different locations. All you need is OXYGEN-NET and a reliable network. This allows you to use all available measuring nodes and control them from the main device.
- Create a virtual measuring device with multiple measuring nodes.
- Easily add or remove measurement nodes with just one click.
- Work with absolute synchronization or with the TRION SYNC BUS.
- Save your measurements locally and remotely – always benefit from the reliable backup of your measurement data.
CAN-OUT
With the optionally available CAN transmission function, the OXYGEN channels are transmitted cyclically to the CAN bus. This means that all the data you have recorded is available on the CAN bus.
- Transmit and receive data on the same bus at the same time.
- Drag’n’drop the channels onto the CAN signal.
- Select your individual transmission interval for each CAN message.
- Individually adjust the transmission delay and thus decide between quality and responsiveness.
ETHERNET RECEIVER
With the optional Ethernet receiver, you can use other data sources in our OXYGEN measurement software, which is already installed on the PU[REC]. It supports the decoding of UDP packets in the OXYGEN channels. This allows you to display and record all your data. In addition, data can be output via UDP streams for monitoring various instances.
- Support for one or more receiver instances for decoding more than one data stream
- Simple XML decoding structure for packet description
- Optional time synchronization with timestamp decoding
SOUND-LEVEL-OPTION
Determine the time-dependent sound pressure level or the energy-equivalent continuous sound level with the optional sound level option. You can also freely define the static sound pressure level and use many other features:
- A-, B-, C-, D- and Z-frequency weighting (in accordance with DIN EN 61672-1)
- Fast, slow and impulse time weighting (in accordance with IEC 651)
- Reference level for airborne sound (20 μPa) and water (1 μPa)
- Total and interval logging
USER-FRIENDLY MULTI-TOUCH DISPLAY
The PU[REC] datalogger has a bright 15.6” multi-touch Full-HD display for quick and easy operation. The high-resolution display guarantees the display of your measurement data even in harsh environments. You can use our intuitive measurement software OXYGEN via simple multitouch gestures and smart visuals like you would on a smartphone. Alternatively, you can connect a keyboard and a mouse too.

SIMPLE & MOBILE MEASUREMENTS
The versatile PU[REC] is especially designed for rugged environments and is ideal for analyzing electrical or mechanical components. Utilize it for maintenance, quality assurance, repair, servicing, engineering, or long-term monitoring. Record voltage, current, temperature, bridge, acceleration, CAN, digital inputs/outputs and much more absolutely synchronously and seamlessly.
