Redpost RPU-120+ electronic temperature recorder

The Redpost RPU120+ special-purpose electronic temperature recorder is specifically designed to monitor the tunnel pasteurisation process. Using the same third generation technology as the RPU-352, the recorder is designed to cover the same temperature range as its predecessor but with greater accuracy and longer recording time.

The instrument passes through the pasteuriser with the product and after the run, the PU value is automatically calculated, together with several other important results. 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 is designed to prevent product spoilage by calculating the temperature of the product when it leaves the pasteuriser, this exit temperature is shown with the other results.

Results are displayed on the instrument allowing immediate confirmation of correct pasteurisation. The display can show graphs and lists of recorded data before the data is printed or transferred.

The recorder is compatible with Redpost's RPC-80 and RPC-50 printer/chargers, which can be used to print reports or transfer the data to a computer for storage and further analysis. The recorder is also backwards compatible with the RPC-40, RPC-42 and RPC-44.

The controls are simple and the display shows operating prompts and results in a choice of languages. Many functions of the equipment can be configured to suit particular requirements. 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 available with a range of temperature probes for both bottles and cans, spray water temperature probes, mounting frames, and test plugs for on-site checking of calibration. Instruments and probes are calibrated at time of manufacture against standards traceable to U.K National Standards.
