Product Details Implantable and Biocompatible: The DST centi-T temperature data logger is hermetically sealed and made from biocompatible ceramic and epoxy, designed for simple animal implantation and retrieval. The unique ceramic housing guarantees biocompatibility. Applications: Ideal for studies on both free-ranging and captive animals where a detailed temperature profile is needed, including baseline measurements, immune response to infection, vaccine efficacy and safety pharmacology, and physiological changes and circadian rhythm. Stress-Free Measurements: Automatically measures temperature, providing a comprehensive data set throughout research with no disturbance to the animal. Detailed Temperature Profile: Long battery life allows for both long-term and short-term studies with short intervals (down to once every second). Battery life is up to 9 years when sampling at 10-minute intervals. Sampling Modes: Two modes for sampling: single interval throughout the period or multiple intervals. Multiple intervals are useful for frequent measurements at certain periods. Memory Extension: Available with extended memory capacity to store up to 524,066 temperature measurements. Guaranteed Accuracy and Performance: Each logger is individually calibrated and comes with a calibration certificate. Accuracy and performance are guaranteed for one year after purchase. Simple Use: Designed for ease of use from setup to data retrieval. Supported by Mercury software and a Communication Box (both required for first order). Programming: Logger is started via the Communication Box and software, where start time, date, and sampling interval are set. Multiple Measurement Intervals: Different intervals can be set for the same study, optimizing data space and battery life. Memory and Battery Calculations: Software calculates when memory fills and estimates battery consumption. Data Upload: Data is uploaded to the software after logger retrieval, displayed in graphic and tabular form, and can be exported. Reusable: Logger can be sterilized and reused as long as the battery lasts. Battery life can be checked in the software. Hermetically Sealed: All Star-Oddi loggers are leak proof; battery is not replaceable. Accessories: Communication Box (for wireless data transfer and connection to PC via USB) and Mercury software (for setup, data retrieval, and export). Implantation: Leadless design and small size make implantation simple and minimally invasive. Suitable for medium to large animals such as cattle, sheep, pigs, and bears. Sterilization: Loggers can be sterilized and reused for as long as the battery lasts. Not all sterilization methods are suitable; avoid methods exceeding 60°C.
