MEASUREMENT SOLUTIONS FOR BIO SCIENCES

DPTV 2 is fast and intuitive video tracking software for non-invasive measurements of water velocity in rectilinear flows. DPTV 2 is the ideal tool for water velocity calibrations in 170 mL and 1500 mL Loligo^® swim tunnels and other Blazka-type swim tunnels with limited access or space for flow probes. The software is also part of our flow tracking system.

The velocity measurements are based on 2D video tracking of green laser illuminated fluorescent spheres with neutral buoyancy. DPTV 2 will automatically calculate average flow velocities and direction from video images, and provide a calibration file that can be used directly in our different swim tunnel software. You can also perform a manual velocity calibration using recorded video files from your own camera or from a camera system from us.

Please note that you will need a DAQ-BT device and one of our cameras to fully automate the calibration procedure in DPTV 2, and for real-time flow measurements.

There is a free DPTV 2 demo available (see FILES/DOCUMENTS below).

Here is a quick video tutorial of DPTV 2.

Open flume tank system for force-swimming individuals or groups of zebrafish fry-juveniles (or similar) in a controlled recti-linear flow. Water velocity can be adjusted from 2-28 cm/s with a diaphragm valve or by changing the (included) pump flow rate. The exact flow is monitored in real-time with an inline paddlewheel (inductive) flow sensor and a transmitter with a digital display. Swimming animals can be filmed from left and right as well as from above and below. The open test section makes it easy to add or remove specimens. Typical applications include zebrafish phenotyping, swimming performance, exercise physiology, behavior etc. in freshwater or seawater species.

NOTE: The diaphragm valve and paddlewheel flow sensor is included. Mesh diameter size (in honeycomb and metal mesh) can be changed upon request. Contact us for more information.

Animal ID made easy! This ergonomic but robust handheld PIT reader is splash-proof (IP65) and made for challenging environments like fish science or aquaculture applications.

PIT tag data are transferred to the PC via USB or Bluetooth, and in addition the device can store up to 100.000 records in several groups in the large internal memory. Each record also contains a timestamp plus a Visual ID and an Alert, if available.

The reader has a large color display which can show many information at one glance. Together with the seven keys, it allows the easy and convenient navigation through menus and data. In addition, the device has status LEDs above the display for indicating charging- and interface status plus the reading status. The integrated speaker provides acoustical feedback to the user and the vibrating motor is very useful in noisy environments.

Weight data can be imported from all major brands of scales via Bluetooth and it can be recorded in combination with the Animal ID in TASKs.

The following accessories are included in the set:

• PIT reader
• USB-A to Magnetic-Connector cable
• USB power supply
• Car charger (12VDC)
• Suitcase
• Software for Windows
