Temperature data logger DST centi-HRT ACT

heart rateactivityfor aquatic animals

Long- or short-term overview of changes in fish or aquatic animal heart rate, activity, and temperature. Minimally invasive, leadless, and simple to implant. The most comprehensive tool on the market to measure individual physiological response of fish. Enables long term aquaculture monitoring, welfare, thermal tolerance, and swimming physiology. Key features Small, size 15 mm x 46 mm, 19g, long battery life Leadless, minimally invasive Statistical and raw 3-axis accelerometer data ECG derived heart rates as low as 4bpm Guaranteed pressure tolerance to 800 m Small and long battery life The DST centi-HRT ACT is a small heart rate, activity and temperature logger that weighs 19g in air, with a diameter of 15 mm and length of 46 mm. Long-term heart rate and activity studies are simple to set up. You can expect a battery life lasting several months, typically between 2-17 months*, depending on sampling frequency and measurement interval. Published data from several fish species Star-Oddi loggers, available in five sizes, have been used successfully in several publications in various salmonid and other fish species. Fish weighing from approximately 120g up to several kg. The DST centi-HRT ACT is ideal for use in physiological and behavioural research on aquatic animals over 760g. Published studies include thermal tolerance and swim speed tests. Small and minimally invasive The heart rate and activity logger DST centi-HRT ACT simultaneously measures long-term heart rate, activity, and body temperature. The logger has no external wires, which makes it especially simple to implant. The logger is hermetically sealed for biocompatibility.
