Tinytag Data Loggers

TG-4080 Tinytag Transit 2 Data Logger

Bright Yellow Case

The Tinytag Transit 2 TG-4080 is a robust, lightweight, and cost-effective temperature data logger designed primarily for shipment monitoring and cold chain verification. Housed in a bright yellow case, this specific variant is optimised for applications where the logger is found in shipping containers and needs to be located quickly to verify that alarm temperatures have not been breached. Fully BS EN 12830 compliant, the TG-4080 delivers reliable, tamper-proof temperature mapping to ensure product safety and regulatory validation during transit by road, rail, sea, and air.

Core Features & Technical Breakdown

  • Low-Profile Enclosure: Measuring just 15.3 mm thick, the sleek, circular yellow housing allows the logger to slide smoothly into tight spaces, shipping boxes, or thin packing cases. The bright yellow colour makes it to easily located in shipments for quick retrieval and transport temperature validation
  • High-Capacity Internal Memory: Stores up to 8,000 continuous readings using a precise internal 10K NTC thermistor sensor, capturing granular thermal profiles with a high resolution of 0.01°C or better.
  • Dual Offload Capabilities: Data can be extracted via a standard direct USB cable (CAB-0005-USB). Alternatively, for high-throughput logistics depots, it natively supports the ACS-3030 Inductive Pad. This allows technicians to offload multiple loggers instantly by placing them onto the pad without removing lids or plugging in cables, preventing ambient condensation build-up inside the unit.
  • Flexible Trigger & Delay Profiles: Offers a delayed start option (up to 45 days) or a magnetic switch trigger. Passing a magnet over the casing’s edge activates logging immediately in the field, turning the green LED from a slow status flash to an active tracking pulse.
  • Fully Programmable 2-Alarm Thresholds: Features user-defined high and low alarm limits. If a climate breach occurs during shipping, a dedicated red LED flashes continuously, giving receivers immediate, visual warning of a compromised consignment.

Core Technical Specifications

  • Measuring Range: -40°C to +70°C (Tested to EN 12830 for frozen and chilled food logistics).
  • Logging Interval: Fully programmable from 1 second up to 10 days.
  • Case Protection: IP54 Splashproof rating.
  • Dimensions & Weight: 60.2 mm} Diameter X 15.3 mm Thickness; Weight is a featherlight 28 g.
  • Internal Battery: User-replaceable Renata CR2325 battery with an expected 1-year operational span.

Core Accuracy & Regulatory Compliance

Accuracy Threshold: The TG-4081 achieves a precision reading accuracy of 0.4°C between 0°C and +50°C.

This precise thermal response is critical for verifying compliance with international cold-chain standards. The logger is fully certified to BS EN 12830 standards (covering categories S; T; C; D; 1), meaning it meets all legal traceability requirements for the transport, storage, and distribution of chilled, frozen, and deep-frozen foodstuffs as well as temperature-sensitive biopharmaceuticals.

High-Visibility Yellow Casing Advantages

In contrast to its covert counterpart, this specific variant is housed in a high-visibility bright yellow case, intentionally designed to be easily spotted inside dark shipping containers, deep commercial freezers, or busy warehouse floor environments to prevent the unit from being accidentally left behind or lost during cargo offloading. It tracks internal temperatures from -40 to +70°C to safeguard the integrity of high-value pharmaceuticals and chilled food shipments. For rapid diagnostic checks on the move, the TG-4080 data logger can be programmed to flash the Red LED when the temperature exceeds limits set by the customer, providing immediate visual alerts to warehouse personnel without needing an instant data download.

Tinytag Infrastructure

If your facility monitors both goods in transit and static storage environments, the TG-4080 integrates seamlessly into a broader corporate tracking network:

  • In-Transit Logging: Use the low-profile Transit 2 to travel seamlessly inside small boxes, shipping packages, or shipping containers across road, rail, air, and marine freight legs.
  • Static Facility Logging: Pair it with the Tinytag Talk 2 inside your central distribution centres, medical refrigerators, or climate-controlled cleanrooms.
  • Ultra-Low Temperature Cold Chain: For cryogenic shipping, the Tinytag Dry Shipper loggers track deep-frozen assets down to -80°C or -196°C} using specialised liquid nitrogen configurations.
  • Unified Management: Both hardware families use identical data loop logic and are programmed, downloaded, and analysed using the exact same Tinytag Explorer Software. This allows your logistics team to merge transport charts and static warehouse temperature profiles onto a single master validation report.

Applications

Monitors environmental parameters during the transport of chilled, deep-frozen, and quick-frozen products to verify temperature threshold stability and enforce safety compliance under BS EN 12830 standards.
Slips easily inside clinical drug packaging or container shipments due to its ultra-low profile, tracking temperature-sensitive biologics and vaccines across air, land, or sea freight.
Deploys within cargo packaging to monitor environmental consistency while the high-visibility yellow body guarantees easy device reclamation at destination delivery hubs.
Audits local temperature variations inside commercial walk-in freezers, holding refrigerators, and multi-stage distribution centres.

Frequently Asked Questions

▶ Q: Why is the TG-4080 housed in a bright yellow casing instead of a neutral grey housing?
A: The high-visibility yellow casing is purpose-built for fast identification in chaotic logistics environments, making it easy for handlers to locate and retrieve the logger from large cargo crates or deep storage racks.
▶ Q: How does the TG-4080 visually alert users to a temperature breach during transit?
A: The TG-4080 data logger can be programmed to flash the Red LED when the temperature exceeds limits set by the customer, allowing floor staff to spot an environmental violation at a glance.
▶ Q: How does the bright yellow TG-4080 handle public area monitoring compared to the grey TG-4081?
A: Unlike the discreet grey model designed to blend into the background, the bright yellow TG-4080 acts as a highly visible deterrent on open retail shelves or public pharmaceutical fridges, signalling that continuous quality auditing is in progress.
▶ Q: Does the bright yellow colour of the TG-4080 aid in low-light environments?
A: Yes, the vibrant high-visibility yellow casing is specifically selected to ensure the logger can be quickly located under poor lighting conditions, such as inside deep walk-in blast freezers, unlit cargo holds, or the back of delivery vans.
▶ Q: Is the programmed flashing Red LED visible through industrial packaging?
A: While the high-intensity Red LED is bright, it is designed for clear visibility when the logger is mounted on walls, open shelves, or placed in clear plastic shipping pockets; if buried deep inside opaque bulk pallets, the grey TG-4081 is typically preferred for covert data harvesting at destination.
▶ Q: Can both the yellow and grey casing loggers be offloaded using the same equipment?
A: Yes, both variants share identical internal architecture, meaning a single inductive pad (ACS-3030) or starter kit cable can program and download data from both the high-visibility TG-4080 and the discreet TG-4081 interchangeably.
