Radio data logging monitors medical products

Chichester, West Sussex, UK:  Pharmaceutical manufacturer STD Pharmaceutical Products is using the Tinytag radio data logging system to store sensitive products in the correct conditions. The System uses wireless communications to send temperature data for immediate viewing on a PC.

Some of the company’s products require storage conditions below 25°C, and the temperature has to be constantly monitored to ensure the product remains compliant. Six radio data loggers, some incorporating two probes, are located in the main warehouse at different height levels; there is a clear difference of 2°C between the differing levels. A logger is also located in the cold store to identify any temperature deviation within that area, and there is also one in the server room to help protect the IT systems from overheating.

The data is analysed monthly unless an alarm is automatically generated by the logging system. An annual report is produced in line with current MHRA (Medicines and Healthcare products Regulatory Agency) guidelines for the company’s Wholesaler Dealers Licence.

The radio option proved to be the most flexible solution for STD as the loggers can be situated wherever required, and they support each other by automatically re-routing the signal (or recording locally) if it is blocked or the battery has died, so the data is not lost. The radio loggers all feed into one hub, which is linked to the company’s server. Additional loggers and probes can be added if required at a later date making the system very flexible.

Louise Payne at STD Pharmaceuticals says: “We are very satisfied with the results of the loggers; previously we used loggers which recorded the minimum and maximum temperatures for the previous day.  Tinytag radio loggers use real time, and are also able to log historic data: if there is an issue an automated alarm can be sent direct to our e-mail, mobile device or telephone, and the software is simple and effective to use.”
