General information

S-Radio Flexible wireless temperature data logger up to 140°C with flexible probe to place the device near the packages instead on top and with rigid probe for penetration.

S-Radio Flexible is a wireless  temperature data logger from -40°C to 140°C (calibration from 25°C to 140°C) with 30 cm felxible probe and 50 mm or on demand length external probe (probes cannot be switched) on a 5 mm base (base height is not counted for probe length), managed with Windows software and USB interface. Battery is user replaceable and the data logger is provided with an Accredia (NIST equivalent) traceable cetificate on 4 points.


View process data in real time

Thanks to S-Radio process data can be viewed in real time on PC screen along with progressive lethality (pasteurisation units) values. Alarms can be set on temperature and lethality value itself. With P-Radio you can act in real time on the process, knowing the thermal curve at the core of the product.


Other versions

The other versions of the data logger are:

  • S-Radio: with rigid probe of different lengths
  • S-Radio 100 / 5 mm: with 100 mm length, 5 mm diameter rigid probe
  • S-Radio Bendable: with semi-rigi metal bendable probe and rigid probe at the end

The version for up to 100°C is available too, along with flexible, bendable versions.

It is part of a series of data loggers divided in P-Radio (up to 100°C) and S-Radio (up to 140°C). They require an interface for PC connection: DiskInterface HS, Multibay. For real time data the USB Radio Receiver is needed as well.

There are also other models of high temperature data loggers, for pressure and humidity too.
