Product Details Temperature data logger designed for animal implantation. DST centi-T temperature sensor provides detailed timeline temperature profile for both short and long term studies in water or on land. Minimally invasive probe and easy to implant. Ideal for use in studies on medium to large captive and free-ranging animals, especially for animal welfare research on mammals and livestock like cattle, cows, sheep, and pigs. The thermistor probe has biocompatible housing. Key Features Minimally invasive and simple to implant Small size (19g) and long battery life – up to 9 years Stress-free measurements Detailed temperature profile Guaranteed accuracy and performance Description The temperature data logger is hermetically sealed and made from biocompatible housing, ceramic and epoxy, and is designed for simple animal implantation and retrieval. The unique ceramic housing guarantees biocompatibility. Application The data logger is ideal for a variety of studies on both free-ranging and captive animals where a detailed temperature profile is needed, including for: baseline measurements, measuring immune response to infection, testing vaccine efficacy and safety pharmacology, and measuring physiological changes and circadian rhythm. Stress-free measurements As the logger measures temperature automatically it is especially useful when a comprehensive data set throughout the research is needed with no disturbance to the animal. Detailed temperature profile Due to its long battery life the logger can be used for long term, as well as short term studies with short intervals (down to once every second), giving the user a detailed temperature profile; the logger has a battery life of up to 9 years when sampling at 10 minute intervals. Single or multiple intervals There 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. Memory extension available The logger is available with an extended memory capacity that can store up to 524,066 temperature measurements. Guaranteed accuracy and performance Every logger is individually calibrated and comes with a calibration certificate. The loggers’ accuracy and performance are guaranteed for one year after purchase. Using the logger Simple in use, from setup to data retrieval The logger and the accompanying accessories are designed for ease of use throughout the research process, from setting up the logger, implanting it, to retrieving and analysing the data. The logger is supported by Mercury software and a Communication Box which need to be purchased with the first order. Programming the logger: To start the logger for measurements it is placed into a Communication Box and connected to the software. The Communication Box serves as an interface between the logger and a PC computer. In the application software, the user sets the start time, start date and sampling interval before starting the recorder. Multiple measurement intervals: Different measurement intervals can be set for the same study. This is especially useful when more or less frequent measurements are needed at a certain time period, saving data space and battery. Memory and battery life calculations: The software automatically calculates when memory fills based on certain interval settings, making it easier for the user to decide how to program the logger. Estimated battery consumption during that time period is also calculated. Uploading the Data: After recovering the logger, the logger is inserted into the communication box and the recorded data is uploaded to the software. The results are displayed both in graphic and tabular form and the data can be exported to other programs. Reusable: After retrieving the data the logger can easily be sterilized and reused as long as the battery lasts. Current battery life can be viewed in the software and the user can get an estimate of how long the logger memory and battery will last in a planned research. Hermetically sealed: All Star-Oddi loggers are hermetically sealed and leak proof. Therefore the battery is not replaceable. Accessories Communication box: Serves as an interface between the logger and a PC computer. Used for connecting to the DST, when starting the logger and retrieving data. DST is inserted into the hole of the box for wireless communications. The box comes with a USB cable for connecting to a PC computer. Mercury software: Graphical Windows supporting software for the laboratory and wildlife sectors. Offers various options for measurement setup and graphical and tabular view of retrieved data. The data can easily be exported to other programs and all updates are free of charge. Implantation Minimally invasive: Due to the leadless design and small size of the loggers, implantation is simple and minimally invasive. Suitable animal size: The DST centi-T is suitable for medium to large animals, such as cattle, sheep, pigs and bears. Sterilization: The loggers can be sterilized and reused for as long as the battery lasts. As Star-Oddi’s loggers contain electronics not all sterilization methods are suitable; this includes methods where temperature exceeds 60°C.
