Heatwatch Protect sensitive products and monitor shelf-life with HeatWatch TR-1

HeatWatch™ TR-1 Label Configuration The HeatWatch TR-1 is a new concept in temperature and spoilage monitoring.  The TR-1 is based on the Dallas Semiconductor Themochron iButton® temperature recorder.  The TR-1 tracks and calculates spoilage based upon a user-defined profile.

The user can program the TR-1 to create an electronic simulation of the goods being monitored.  With the TR-1 behaving and reacting like the product, the user can access the unit and poll the TR-1 database to determine the condition and remaining shelf life.  These critical factors are determined by the history of the storage environment and the specific spoilage characteristics of the good.

Software

The TR-1 utilizes a patent pending software package for programming and data retrieval.  TR-1 software is very user friendly and utilizes a minimal number of screens to provide the required functionality.  The primary screens are Settings, Database, and Spoilage Profile.

Heatwatch Label, Heatwatch Interface Cable and Thermicron iButton

The Settings screen is used to program the Heatwatch TR-1 unit and launch a recording mission.  Specific information such as the spoilage profile to be referenced, the sample rate, alarm set points, mission name, and the quantity of TR-1 devices to be used are selected and programmed from this screen

The Spoilage Profile screen is used to construct the specific profile that will be referenced.  Up to 40 data points can be entered to describe the time/temperature relationship for the product.  The user may also select and construct a “High Quality” profile based on the minimal spoilage profile but providing leeway for quality.

The Summary screen details the mission name, spoilage profile used, start timstop time, high and low alarm times, as well as a graph of the remaining Shelf Life.  This screen also includes a future storage calculator that details how long a product may be stored at a given temperature based upon shelf life already depleted.

A Database screen displays previously downloaded mission.  When a specific mission is accessed various graphs can be reviewed that depict different aspects of that mission.
