TemPTrak, Electronic event tracker and paperless recorder is a totally in-house developed, micro controller based hardware with sophisticated software based event recorder with high resolution, for all temperature recording activities, on a continual basis with full audit trail.
Suitable for all critical applications involving temperature tracking in refrigerator, platelet incubator, plasma and red cell freezers, in line with regulations requirements in case of blood banks or applications involving storage of precious material in pharmaceutical, clinical research, biotech, healthcare or any field where compliance requirements are to be met, or wherever continuous event tracking is critical for the “mission”.
Many research labs and blood banks, for temperature recording, have been using mechanical seven day circular chart recorder for ages now. It is often
overlooked that recorder is an apology for the real tracking of “actual temperature”, or “actual variations in temperature”, or “actual time duration of violation of alarm conditions”, primarily due to poor resolution and basic limitation imposed by design.
Majority of seven day circular chart recorders are with a radius of 6 cm, with the movement of pen over a circumference of 37.7 cm over a period of seven days
translating into one cm accounting for 265 minutes, or almost 25 minutes corresponding to one mm pen movement on the chart! So conventional seven day chart recorder does not serve any purpose say when the temperature alarm limit is ± 2oC at the set temperature of 4oC, or 22oC, under typical storage conditions, in relation to the resolution. There is no indication for significant temperature deviations occurred,or time duration of alarm(s) due to poor resolution and absence of storage possibilities.
Wheecon team found a way around to solve these limitations, in the most elegant manner by seamlessly integrating a dedicated microcontroller for data
acquisition over small time interval, and touch screen for easy user interface and data input, presentation and storage. The final output is a resultant of the processed temperature and time data acquired, and presented graphically in conventional circular chart or bar graph or linear form or as chart table, using
Software provides facilities for presenting at a glance, day, time, actual temperature and violations or distilled information on alarm conditions alone. The
data is stored on-board for easy retrieval and review on user selectable format and time scale – hourly, daily, weekly, monthly or yearly basis. The data as being acquired is stored on-board offering total back-up as the first level security and can be transferred for long term storage in pen drive or SD card and with option to export data to LIMS through wire or wireless network.
