Tinytag radio data loggers monitor the temperature in climate controlled storage areas, as well as providing environmental monitoring in a server room to prevent overheating.
Leading medical equipment and pharmaceutical manufacturer
STD Pharmaceutical Products Ltd is using the
Tinytag Radio Data Logging System to ensure
that its sensitive products are stored in the correct conditions.
The System uses wireless communications to send temperature data
for immediate viewing on a PC.
STD Pharmaceutical Products is a family run
business formed in 1967 to supply a novel sclerosant (injectable
medicine) to surgeons for the non-surgical treatment of varicose
veins. The company currently promotes a range of sclerotherapy
products, antiperspirants and also offers treatment for
hyperhidrosis (excessive sweating). This includes tap water
iontophoresis machines, a non-invasive procedure which passes a low
voltage electric current through the hands or feet using a water
bath. Both products offer patients genuine alternatives to surgical
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 on a monthly basis unless an alarm is
automatically generated by the logging system. If this occurs,
steps have to be taken immediately to investigate if any product
could be at risk. An annual report is produced in line with current
MHRA (Medicines and Healthcare products Regulatory Agency)
guidelines for the company's Wholesaler Dealers Licence.
STD Pharmaceutical Products initially selected
Gemini Data Loggers due to the information and
experience that was readily available. The radio option proved to
be the most flexible 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 of STD
Pharmaceuticals commented, "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."
