DST micro-HRT heart rate and temperature logger

The heart rate sensor DST micro-HRT simultaneously measures long term heart rate and core temperature in animals. This makes it ideal for studies in which baseline and immunology responses are recorded, it's also suitable for toxicological, metabolic and thermoregulation studies. The heart rate is derived from a leadless single channel ECG in which the electrodes are part of the housing material, making the logger especially easy to implant. The logger then takes a burst measurement on any set time interval and calculates the mean heart rate for each recording. Each burst recording of heart rate consists of 600 measurements. For validation purposes, each individual burst is graded with a certain quality index (QI) accessible in the accompanying application software. It is possible to save bursts at certain times.

The heart rate sensor can store up to 43688 paired heart rate-temperature measurements and has a battery life of circa 3.5 months (with sampling interval of 10 min). The DST micro-HRT logger is easy to sterilize and can be reused as long as the batteries last. Each DST micro-HRT has its own five digit serial number permanently marked on the logger housing as well as placed in the logger's memory and provided with all downloaded data. DST micro-HRT is especially useful when you wish to record a comprehensive data set throughout your research with no disturbance to the animal. Each logger comes with a calibration certificate.

The DST micro-HRT is supported by the Mercury software and the Communication Box which serves as an interface between the logger and a PC computer. Communication between the logger and the Communication Box is wireless when logger is placed in the Communication Box.

In the software, the user programs the start time, start date and sampling interval before the logger is implanted. A single interval is defined in minutes or hours, fastest interval is 1 minute. Optionally it's possible to program with multiple intervals; up to seven different intervals can be used within the same measurement sequence. The user would then define the number of measurements to be recorded within each interval and thereby have more/less frequent measurements during specific time periods.

After recovering the DST, recorded data is uploaded in the software where the results are displayed both in graphic and tabular form. The software also provides the user with some basic statistic information on the data such as minimum and maximum values on defined area, median, average, distribution of values etc. When recorded data has been retrieved, the DST can be re-programmed and reused as long as the batteries last.

A set of Communication Box and Mercury software needs to be purchased with the first order.
