Leadless, minimally invasive, and easy to implant. Long term heart rate and body temperature.
Ideal for long- and short-term physiological studies to measure cardiac function in aquatic animals and fish. Published studies include baseline, stress response, thermal tolerance, and swim speed tests.
Key features
Small size, 13 mm x 39.5 mm and 12g, long battery life
Leadless, minimally invasive
ECG derived heart rate, records down to 4bpm
Guaranteed pressure tolerance to 800 meters
Automatic stress-free measurements
Fairly small and long battery life
The DST milli-HRT is a relatively small heart rate and temperature logger that weighs 12g in air, with a diameter of 13 mm and length of 39.5 mm. Long term heart rate studies are easy and simple to set up. You can expect to get a battery life that can last over several months, typically ~ 8.5 months, depending on sampling frequency and measurement interval.
Published data from several fish species
Star-Oddi loggers, available in four sizes, have been used successfully in several publications in various salmonid and other fish species. Fish weighing from approximately 120g up to several kg.
Leadless, Minimally Invasive
The DST milli-HRT simultaneously measures long term heart rate and temperature in the study animal. The logger has no external wires, which makes it especially simple to implant. It is made of unique ceramic housing and epoxy and is hermetically sealed, guaranteeing biocompatibility.
