Temperature monitoring for Covid-19 samples

26 June 2020

Omniflex has supplied an SMS alert system to the University of Oxford’s Peter Medawar Building for Pathogen Research.

The remote module allows researchers to receive 24/7 alerts directly to their mobile phone in the event that freezers holding samples deviate from the critical temperature window. 

Omniflex has supplied its Teleterm M3 GSM remote terminal unit (RTU). The device connects using a serial ModBus port to the labs’ Eltek Monitoring system that controls a number of liquid nitrogen and -80°C freezers.

If the RTU detects a temperature fluctuation that exceeds the allowable limits set by the monitoring system, it automatically sends alerts via email or SMS to designated email accounts or mobile phones anywhere in the world. The user must then reply to acknowledge the alarm condition. If the unit fails to receive a response, the system escalates the alert.

As well as alerts, users can also use Omniflex’s web portal, Data2Desktop, to access the system remotely using any device, including smartphone, tablet, laptop or PC. The web-based system also logs all historical events and automatically generates a daily, weekly and monthly report summarising deviations and alarm events for conformance reporting.
