Description
The heart rate sensors DST...RF-HRT simultaneously measure long term heart rate and core temperature in animals. This makes them ideal for studies in which baseline and immunology responses are recorded, they are 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. For validation purposes, each individual burst is graded with a certain quality index (QI) accessible in the accompanying application software.
Easy to use and reuseable
The heart rate sensor is simple in use, from setup and surgery to data transmission and retrival. DST ...RF-HRT logger is easy to sterilize (gas sterilizer or 70% ethanol) and can be reused as long as the batteries last, which makes the logger very cost efficient. Each DST ...RF-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 ....RF-HRT is especially useful when you wish to record a comprehensive data set throughout your research with no disturbance to the animal or subject. Each logger comes with a calibration certificate.
Easy to use and reuseable
The telemetry system consists of seven components: DST... RF-HRT telemetry data logger with a heart rate and temperature sensor, a RF box transreceiver module placed on each cage, an antenna placed on each cage, a Personal Area Network (PAN) controller which is the receiving module connected to a computer, Communication Box which serves as an interface between the logger and the PC, and Mercury and Gná application software. The DST microRF-HRT is based on our DST micro-HRT and gives the users the benefit of both continuous logging and telemetry. The logger can be programmed to record temperature as often as once per minute. It will store those data points in its memory and transmit the data to Gná, our online user software, as often as required by the researcher. The measurement data can be analysed in graphic and tabular form and exported to most statistical analysis programs. 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.
The Telemetry System

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.
There can be up to 10 subjects in each cage. The RF box will receive the data from the DST microRF-HRT and transmit it to PAN. The software takes care of minimizing cross talk and even if that does happen all transmissions have the individual logger’s ID attached.
Each telemetry system needs to have a PAN to receive the data from the RF boxes. It is connected to the computer using a serial cable and a USB converter. How far the PAN can be placed away from the RF box varies greatly on the configuration of the lab but in most cases it will transmit about 20-30 meters.
