Temperature data logger DST micro-TD

pressuredepthfor animal research

Product Details: The DST micro-TD is the world's smallest temperature and depth logging archival fish tag, ideal for very small fish or marine animals for long-term behaviour and migration studies. Developed in cooperation with fish biologists, it is suitable for tagging very small fish, smolts, and marine animals for extended research periods. Despite its small size (25.4 mm x 8.3 mm, 3.3 g in air), the DST micro-TD Data Storage Tag offers high reliability and a long lifetime, making it perfect for long-term studies. Small and reliable archival fish tag Long life and flexible interval setup Depth sensors for different ranges (user selectable: 150 m, 300 m, or 1000 m) Fish implantation or external attachment (biocompatible housing) User-defined text on the housing for recapture purposes The DST micro-TD can store up to 87,168 measurements, allowing for data storage over 2.5 years at a 30-minute interval. The logger supports multiple intervals, enabling different intervals for depth and temperature measurements. The tag can be implanted in the abdominal cavity or attached externally using a tag holder kit. For easier identification, a yellow plastic tube (spaghetti tag) can be attached, making tagged fish more visible. Usage: Simple setup and data retrieval using the SeaStar software and Communication Box (purchased separately) Programmable start time, date, and sampling interval via PC Supports single or multiple sampling intervals (up to 7 different intervals) Automatic memory and battery life calculations in software Data upload after recapture, with results displayed graphically and in tables Long battery life (up to several years depending on usage) Accessories: Communication Box: Interface for connecting DST to PC for setup and data retrieval SeaStar software: For Windows, required for operation, data visualization, and export Plate Holder Kit: For external attachment, includes wire fasteners, plastic plates, and silicone pads Capsule Holder Kit: Plastic capsule with holes for water flow, wire harness, and silicone pads Floating Device: Available in two sizes, for internal or external tagging, can be coated or painted for visibility Technical Specifications: Sensors: Temperature and pressure (depth) Size (Diameter x Length): 8.3mm x 25.4mm Housing Material: Biocompatible alumina (ceramic) Weight (in Air/in Water): 3.3g/1.9g Data Resolution: 12 bits Temperature Range: -2 to +40°C (28°F to 104°F) Temperature Resolution: 0.032°C (0.058°F) Temperature Accuracy: +/- 0.2°C (+/- 0.36°F) Temperature Response Time: Time constant (63%) reached in 8 sec.
