Product Details Minimally invasive and simple to implant: 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: Ideal for a variety of studies on both free-ranging and captive animals where a detailed temperature profile is needed, including baseline measurements, measuring immune response to infection, testing vaccine efficacy and safety pharmacology, and measuring physiological changes and circadian rhythm. Stress-free measurements: The logger measures temperature automatically, providing a comprehensive data set throughout the research with no disturbance to the animal. Detailed temperature profile: With a long battery life, the logger can be used for both long-term and short-term studies with short intervals (down to once every second), giving a detailed temperature profile. Battery life is up to 9 years when sampling at 10-minute intervals. Single or multiple intervals: Two modes for sampling: single interval throughout the period or multiple intervals. Multiple intervals are useful for frequent measurements at certain time periods. Memory extension available: Extended memory capacity can store up to 524,066 temperature measurements. Guaranteed accuracy and performance: Every logger is individually calibrated and comes with a calibration certificate. Accuracy and performance are guaranteed for one year after purchase. Using the logger Designed for ease of use throughout the research process, from setup, implantation, to data retrieval and analysis. Supported by Mercury software and a Communication Box (both required for first order). Programming: Logger is placed in the Communication Box and connected to the software. User sets start time, date, and sampling interval. Multiple measurement intervals can be set for the same study, optimizing data space and battery. Software calculates memory fill and battery consumption based on interval settings. Data upload: After recovery, logger is inserted into the Communication Box and data is uploaded to the software. Results are displayed graphically and in tables, 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 and leak proof. Battery is not replaceable. Accessories Communication Box: Interface between logger and PC. Used for connecting to the DST, starting the logger, and retrieving data. Comes with USB cable. Mercury software: Graphical Windows software for laboratory and wildlife sectors. Offers measurement setup, graphical and tabular data view, and data export. Updates are free. 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. Loggers can be sterilized and reused as long as the battery lasts. Not all sterilization methods are suitable (avoid temperatures above 60°C).
