1. Solution Monitoring System Cup of Chi Systems

2. Security No matter what kind of service is being provided, all organisations or companies need to consider the issue of security. We have researched into a particular security scenario which has yet to have been addressed and devised a solution to the problem.

3. The issue A great number of universities in the United Kingdom run courses which require the use of laboratories. Among these is the University of Portsmouth. As hazardous and valuable substances are easily accessible to all laboratory users, there is a need for more security to monitor and regulate the usage.

4. Our Solution A security device able to constantly monitor a hazardous or valuable substance, measuring the amount that has been drawn out and alerting the relevant authorities in the case of unauthorised actions. A website is updated in real time with all the information of interest to the end user.
