In-Transit Temperature Recorder (DeltaTRAK)

Cold Chain Monitoring with In-Transit Temperature Recorders

The DeltaTRAK In-Transit Temperature Recorder is a highly reliable strip chart time and temperature recording instrument that continuously monitors environmental conditions during transportation of temperature-sensitive products. Essential for refrigerated trucks, rail cars, ocean freight containers, and air cargo, this temperature data logger generates permanent documentation of real-time conditions throughout the cold chain. A view port allows visual confirmation of activation after startup.

Permanent Documentation for Quality Assurance and Liability Protection

These compact recorders create an undeniable paper record of transit conditions. In the event of temperature excursions or product spoilage, the strip chart provides corroborating evidence for insurance claims, customer communication, and regulatory compliance documentation. Each unit carries a serial number for full traceability to specific shipments. Critical for pharmaceutical, food processing, specialty chemical, and medical device shipments where temperature control is non-negotiable.

Reliable Performance Across Global Shipping Conditions.

These instruments function in diverse environmental conditions from truck freezer compartments to cargo holds. The bi-metal coil sensor provides reliable, accurate readings without electronic drift. Solid-state quartz motor ensures precise timekeeping, and the pressure-sensitive chart captures a complete 36-inch record across 5-day to 90-day monitoring periods. CE certification by TUV and NIST traceability ensure acceptance by regulatory bodies and insurance carriers.

Frequently Asked Questions: Cold Chain Temperature Documentation

How do I know if my shipment experienced a temperature excursion?

The strip chart creates a continuous line graph showing temperature over time. Any deviation above or below your acceptable range is visible as an upward or downward spike. You can see exactly when and how long the excursion lasted.

What does "NIST traceable" mean for these recorders?

NIST (National Institute of Standards and Technology) traceability means the recorder has been calibrated against a known standard. This certification is required by FDA, pharmaceutical, and food industry regulators.

Should I choose 5-day, 10-day, or 30-day recorders?

Choose based on your shipment duration. 5-day for regional trucking. 10-day for longer truck routes or rail. 20-30 day for ocean freight. 60-90 day for slow-moving specialty shipments.

Can I reuse these recorders or are they single-use?

Single-use. The chart is the record. Cost per use (around $12-18) is minimal insurance for protecting valuable shipments.

What's the "startup tab" and how does it work?

The startup tab is a mechanical trigger you pull to begin monitoring. After pulling, a view port lets you confirm the mechanism is active. This prevents accidental activation.

How do I prove the record in court or to an insurance company?

The serial number links the physical recorder to your shipment documentation. The strip chart itself is the record. For additional legal protection, photograph the activated recorder before sealing the shipment and the chart immediately after arrival.
