Product Details The DST milli-TD is a reliable temperature and depth archival tag, designed for long-term behavior and migration studies of fish and marine animals. This small yet high-performing biologger features long battery life and large memory, capable of storing up to 1.4 million measurements at user-defined intervals, as fast as every second. Memory and battery life can last for 2.5 years if sampling at a 2-minute interval. The tag measures 39.4 mm x 13 mm and weighs 13 grams. It can record with multiple intervals, shifting between different intervals during the measuring period. Long life and large memory Depth sensors from shallow to deeper water (calibrated up to 800 meters; options: 50 m, 100 m, 250 m, 500 m, 800 m) Fish implantation or external attachment (implantable in the abdominal cavity or attached externally using a tag holder kit) Tag holder kit ensures easier and safer attachment Customized text on housing for recapture purposes Spaghetti tag option for easier spotting of tagged fish Application Designed as an economical fish archival tag for migration and dive behavioral studies of fish and marine animals over a long period. Can be implanted or attached externally, or used as a standalone temperature depth logger in various situations. Using the Logger Supported by SeaStar software and a Communication Box (required for setup and data retrieval) Logger is programmed via USB connection to a PC, with user-defined start time, date, and sampling interval Supports single or multiple sampling intervals (up to 7 different intervals) Software calculates memory fill and battery consumption based on interval settings After recapture, data is uploaded to the software and can be exported; logger can be reused as long as battery lasts Accessories Communication Box: Interface for connecting DST to PC for setup and data retrieval SeaStar software: For Windows, displays data in graph and table, exportable to other programs Plate Holder Kit: For external attachment, includes wire fasteners, plastic holder plate, silicone pads Capsule Holder Kit: Plastic capsule with holes for water flow, wire harness, plastic plate, silicone pads Floating Device: For internal or external tagging, available in two sizes, can be coated or painted for visibility Documentation Migration & Behavior leaflet (PDF) Aquatic animal brochure (PDF) DST milli-TD Data Sheet (PDF) Key Features Long life and large memory Depth sensors from shallow to deeper water Fish implantation or external attachment Tag holder kit ensuring easier and safer attachment Customized text on housing Technical Specifications Sensors: Temperature and pressure (depth) Size (Diameter x Length): 13mm x 40mm Maximum Diameter: 15mm at the closure end Housing Material: Biocompatible alumina (Ceramic) Weight (in Air/in Water): 12g/7g Data Resolution: 12 bits Temperature Range: -1°C to +40°C (30°F to 104°F) Temperature Resolution: 0.032°C (0.058°F) Temperature Accuracy: +/-0.1°C (0.18°F) Temperature Response Time: Time constant (63%) reached in 12 sec.
