Temperature Monitoring

t-scan 200 t-Scan 200 is a proprietary system providing temperature monitoring solutions that can be customised to suit any business - large or small. The t-Scan 200 system has been designed in-house and generates alarms to alert key personnel in the event of refrigeration failure or out of parameter temperature readings. Other system features include automatic email reporting and remedial action input when an alarm is generated, this along with automatic report/graph generation prove due diligence and provide full audit trails for inspection authorities. The logging utility is set up with all the information relating to temperature thresholds, locations, alarm delays, logging frequency, etc. and once set, runs silently in the task bar. Alarms generated automatically get displayed on screen, and also get sent via the external alarm options setting, if set. The Reports & Graphs Viewer can then be used to display the reports and graphs as required. This report viewer can be set up for use on a LAN network across multiple computers allowing simultaneous access to the temperature data database, with each report viewer generating a different report or graph. Having this split approach makes training on the system easier, as the number of functions to remember has been reduced.
