The FlashLink NOW 4G/5G Real-Time In-Transit Logger utilizes the latest technology to protect domestic and export shipments of temperature sensitive products. DeltaTrak’s real-time devices provide the data shippers and receivers need to take immediate action if a temperature excursion occurs. With a single device, users can capture multiple types of sensor data, including location, temperature, and light.

FlashLink NOW incorporates several enhanced features which offer new options for accessing data and contribute to greater ease of use. The addition of an LCD screen enables users to view trip data stored in the unit’s memory.

Misc Info
  • DeltaTrak’s Real Time Loggers have been a game changer for our trucking program. Having the ability to monitor temperature while trucks are in transit has given us peace of mind knowing the quality of our product has not been compromised. The alert notifications, light sensors, and GPS tracking are just some of the great features that have allowed us to make pro active decisions that have strengthened the integrity of our product. The FlashTrak Cloud Service is easy to use and is a great tool to compare and analyze data. The FlashTrak App is super convenient as well. We have used other reliable DeltaTrak products for many years and we were excited to see these added to their lineup!

  • When it comes to making sense of data (in the supply chain) we have found a partner in DeltaTrak. The fact that I could recharge the real-time logger and the dual batteries made a lot of sense to me. It was user friendly and easy to use. With the uncertainty and complexity of today's supply chain, having an effective chain of custody system is not only a clever idea, but a requirement for effective handling of perishable goods.

  • It is my pleasure to recommend DeltaTrak to your company. During these times of crisis, we were fortunate to work with DeltaTrak to source top of the line Non-Contact forehead thermometers and PPE supplies at a real market price.

    As a healthcare organization, we are a common target for price gouging and abusive practices from several vendors. With DeltaTrak, we found a partner that understands our needs and who always provide world class customer service.

  • Dear Fred, I would like express my appreciation for the good business relationship we have had during 2018. The excellent work of Mr. Jorge Hurtado has given me the confidence to continue maintaining our commercial relationship with the DeltaTrak brand.

    Mr. Jorge Hurtado's customer service efforts are outstanding, especially in finding solutions to the challenges that may arise in the commercial process. In my opinion Mr. Hurtado's professionalism is a model for any company, especially when the client is thousands of kilometers away from Modesto, CA. I look forward to strengthening our successful relationship into 2019.

We have never had a customer issue with one of their units and we don’t expect to. We use a wide range of DeltaTrak products and we have been more than happy with every one of them.
