Redpost RPU-120+ pasteurisation temperature recorder

Click2Contact

The Redpost RPU-120+ is a special-purpose electronic temperature recorder designed to monitor the tunnel pasteurisation process. The instrument passes through the pasteuriser with the product and after the run the PU value achieved, together with other data, is calculated automatically. Standard results calculated are: total PUs achieved, time accumulating PUs, time in holding zone, maximum temperature, etc. The temperature sensor reading is shown continuously, allowing the unit to be used as a thermometer.

The monitor helps prevent product spoilage by calculating the temperature of the product when it leaves the pasteuriser. Results are displayed on the instrument allowing immediate confirmation of correct pasteurisation, and the display can show graphs and lists of recorded data before the data is printed or transferred. The RPU-120+ is compatible with Redpost’s RPC-80 and RPC-50 printer/chargers. With these, reports can be printed or the data can be transferred to a computer for storage and further analysis.

All settings are protected to prevent operators making accidental changes to the configured settings. Calibration details can be held in the instrument to aid record-keeping for ISO 9000. A service reminder gives the operator a notification when a service should be considered.

Redpost PU recorders are offered with a range of temperature probes for both bottles and cans, spray water temperature probes, mounting frames, and test plugs for onsite checking of calibration. Instruments and probes are calibrated at time of manufacture against standards traceable to UK National Standards.
