Description
The TandD RTR-602 Wireless Food Core Temperature Data Logger
The RTR-602 wireless core temperature data logger is an easy yet effective way to track temperature and ensure safety for foods and liquids. One press of the REC button logs all your measurement data: temperature, time of measurement, user, item, and judgment result. A Base Unit (RTR500BW) and a Battery Charge Dock (RTR-600BD) need to be purchased separately.
RTR-602 loggers send recorded data to a wireless base station (RTR500BW) from which it is transmitted to T&D WebStorage Service or your own FTP server. That data can then be viewed via browser on WebStorage or by using TandD’s Windows based DataViewer software.
There are four variations of the data logger to choose from:
RTR-602S – Short Sharp Tipped Sensor
- 1 Temperature Channel, Pt1000
- -60 to 250°C Temperature Range
- Short Sharp Tip Sensor Type
- IP68 Waterproof Capacity
RTR-602L – Long Round Tipped Sensor
- 1 Temperature Channel, Pt1000
- -60 to 250°C Temperature Range
- Short Range Wireless Interface
- Long Round Tip Sensor Type
- IP68 Waterproof Capacity
RTR-602ES – Short Sharp Tipped Sensor and Cable
- 1 Temperature Channel, Pt1000
- -60 to 250°C Temperature Range
- Short Range Wireless Interface
- Short Sharp Tip Sensor Type with Cable
- IP68 Waterproof Capacity
RTR-602EL – Long Round Tip Sensor and Cable
- 1 Temperature Channel, Pt1000
- -60 to 250°C Temperature Range
- Short Range Wireless Interface
- Long Round Tip Sensor Type with Cable
- IP68 Waterproof Capacity
Features
One-Push Simple Recording
One press of a button logs all your measurement data: temperature, time, user, item, and judgment result.
Waterproof and Oil Resistant Design
It is designed to be submersible with an IP68 rating and has a oil-tough construction.
Two Types to Choose From:
There are two types of temperature sensor: a straight rod type sensor (one-piece unit) and a cable-to-grip type sensor (easy to measure temperature in steam). Each type comes in two lengths: a shorter one with a sharp tip for stabbing food and a longer round tipped one.
Collect Data with RTR500BW
The RTR500BW* is required for data collection (sold separately). It automatically collects and uploads the recorded data to T&D WebStorage Service. It is also possible to manually download data to a PC.
*A wired/wireless LAN data collector for the RTR500B Series.
Specialized Non-Contact Charging System
A Battery Charge Dock RTR-600BD (sold separately) is required for charging and setting up. It can simultaneously charge two units. At a full charge the units can run continuously for 24 hours.
Upper and Lower Limit Warnings
If a measurement exceeds a set limit the red lamp will light up on the main unit.
Registration of Measurement Items and Users
The software “RTR-600 Settings Utility” makes it easy to register measurement items and users, as well as, create work groups.
Use with RTR500B Series Data Loggers
The RTR-602 can be used in conjunction with data loggers in the RTR500B Series to create a management system for tracking overall temperature during all phases of food preparation; and all with just one Base Unit.

WebStorage Service
Free Online Service for Cloud Data Storage
It’s never been so easy to share your recorded data via the Internet! T&D’s free WebStorage Service is ideal for processing and managing data recorded in remote locations, or for allowing multiple people to view the same data at their convenience. Users can check the current status of data loggers, including battery level and radio signal strength between the Base Unit and Remote Unit. Recorded data can be transmitted to the WebStorage Service from any compatible TandD product. Data storage capacity is 20MB.
Additionally, the data transmitted to T&D WebStorage Service can be accessed via your browser from anywhere, anytime, as long as an internet connection is available. Mobile device apps are also available for devices running iOS and Android.
