We have released an updated version of our DST milli-HRT and DST centi-HRT, leadless heart rate, and temperature loggers.

The change allows users to measure heart rate in animals that naturally have a slow heart rate, such as some fish species, or animals that go into hibernation and torpor, like bears and ground squirrels. 

The loggers have the option of adding a 2.5 times longer ECG recording at all sampling frequencies. This allows them to record heart rates as low as 3bpm.

For more information, don't hesitate to get in touch.
