Enregistreur de données implantable
- Star Oddi - DST centi-ACT
Overview of changes in animal activity over time. Minimally invasive, leadless and simple to implant.
Ideal for use in physiological and behavioral research on animals.
- Leadless, minimally invasive
- Small, size 46mm x 15mm and 19g
- Long battery life – typically 3 years
- Stress-free long-term studies
- Guaranteed accuracy and performance
The DST centi-ACT simultaneously measures long term activity and core body temperature in the animal. The logger is simple to implant and is made from ceramic housing to guarantee biocompatibility.
The logger is ideal for a variety of studies including those looking at behavior, vaccinology and stress response, in the fields of laboratory animal research, wildlife research and animal welfare.
Overview of Changes in Animal Activity Over Time
Measuring acceleration derived activity gives researchers the chance to get an overall view of changes in the study animals’ activity over time. The DST activity data logger measures acceleration in three dimensions, in relation to earth‘s gravity field.
Stress-Free Long-Term Studies
The activity logger has a battery life of over 19 months, when using a sampling interval of 10 minutes. The logger is especially useful when a comprehensive data set throughout the research is needed with no disturbance to the animal.
Different Measurement Intervals
Optionally, the loggers can be programmed with up to multiple different intervals within a measurement sequence. This can, for example be useful when different intervals are preferred during the day or night and can save battery and memory at the same time.
Guaranteed accuracy and performance
Every logger is individually calibrated and comes with a calibration certificate. We guarantee the loggers’ accuracy and performance for one year after purchase.
