温度データロガー DST milli-HRT ACT

動物研究用小型

Leadless, Minimally InvasiveThe heart rate and activity logger DST milli-HRT ACT simultaneously measures long term heart rate, activity and body temperature in the animal. The logger has no external wires, which makes it especially simple to implant. The logger is hermetically sealed for biocompatibility. ApplicationThe logger is ideal for a variety of studies including those looking at behaviour and stress response, in the fields of laboratory animal research, wildlife research, animal welfare, and fish physiology. Correlation Between Heart Rate and ActivityLooking at heart rate and activity together gives researchers an opportunity to identify correlation between heart rate and activity in the animal, for example in stress response studies. The logger comes with the option of either two or three parameters: activity and temperature or activity, heart rate and temperature. Leadless ECG Derived Heart RateThe heart rate is derived from a leadless single channel ECG. As the electrodes are part of the housing the logger is especially easy to implant. The logger takes a burst measurement of ECG at the set time interval and calculates the mean heart rate for each recording. For validation purposes, each individual burst is graded with a QI (quality index) accessible in the application software. Overview of Changes in Animal Activity Over TimeMeasuring acceleration derived activity gives researchers the chance to get an overall view of changes in the study animals’ activity over time. The DST activity loggers measure acceleration in three dimensions, in relation to earth‘s gravity field. Each activity measurement is composed of a burst activity measurement over one minute with a chosen sampling frequency of 0.03Hz-10Hz. Stress-Free Long-Term StudiesThe logger has a battery life of over 6 months, when sampling activity, heart rate, and temperature every 20 minutes. The logger is especially useful when a comprehensive data set throughout the research is needed with no disturbance to the animal. Single or multiple intervalsThere are two modes for sampling, either at a single interval throughout the period or multiple intervals. Multiple intervals are especially useful when frequent measurements are needed at certain time periods. Guaranteed accuracy and performanceEvery logger is individually calibrated and comes with a calibration certificate. We guarantee the loggers’ accuracy and performance for one year after production.
