• Food Core Temperature Data Logger

Food Core Temperature Data Logger

  • Measurement Range: -60 to 250°C
  • Accuracy: ±0.5°C

The RTR-601 is a food core temperature data logger that is effective for HACCP-compliant temperature management for food safety.

The water and oil proof design makes it ideal for use in food-processing environments. The device records temperature, measurement time, user, item, and upper/lower limit judgement result.

It is possible to automatically collect and send recorded data to a designated e-mail address or an FTP server over wireless and LAN network. 

One-Push Simple Recording

With one-push of on the device, it is possible to record temperature, measurement time, user, item, and judgement result (whether the measurement is within the set upper/lower limits).

Superior Water/Oil Resistance

With an IP68 submersible rating, the RTR-601 is perfect for use in food-processing operations.

Auto Data Collection

Recorded data in the RTR-601 can be periodically collected by the Base Unit (RTR-500NW/500AW) via wireless communication, and automatically sent to a designated e-mail address or an FTP server. This makes it perfect for seamless temperature management.

RTR-6BD Dock with Battery Charging and Communication Capabilities

The RTR-601 requires a Battery Charge Dock RTR-6BD (sold separately) to charge internal batteries. By connecting the dock to a PC with a USB cable, the dock also acts as a communication interface for setting up the RTR-601.

Available in 4 Models depending on Sensor Type

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). Further, each type comes in two lengths: the short one having a sharp tip and the long one having a round tip.

Alarm Function Upper and/or lower limit settings can be made as desired for each food item. When the measured temperature exceeds a limited boundary, an alarm condition will be indicated by blinking red LED.

Using with RTR-500 Series Data Loggers

The RTR-601 can be used in conjunction with RTR-500 series loggers, which is perfect for measuring and monitoring ambient temperatures in both indoor and outdoor environments, including warehouses, refrigerators and freezers.
