HEL has developed the Micronote data logging and control tool, allowing research chemists to keep better records.
The Micronote enables chemists to focus on chemistry while providing their company and management with productivity and data records.
The Micronote can be retro-fitted to existing reactors or installed with new systems and is particularly cost-effective in large numbers.
To fit in with a busy fume hood, the Micronote is a compact and easy to use package, utilising three main components: a microprocessor with touch screen interface, intuitive software and an electronics interface with sensors and other devices.
The software consists of a mimic of the equipment logged or controlled.
It starts up as soon as the unit is switched on and the data from any sensors or devices attached is immediately visible on the mimic.
A touch button initiates data recording if needed (this also starts immediately and the data file is automatically saved with the current time and date).
A graphical display of the data is generated automatically, while another touch of a button reveals the relevant data.
Graphical plots are saved directly to the Microsoft clipboard and can later be pasted directly into reports.
There are two main applications of the Micronote: data logging only and data logging and control.
In the case of data logging only, the chemist can choose to log any group of four probes, including temperature, pressure, pH or turbidity.
For process control, the common channels are temperature and agitation; however, liquid dosing and pH control are also possible.
Customised versions of the Micronote are available.
For example, HEL has implemented a simplified version of the calorimetry calculations in one version.
The heat release data is recorded directly (and automatically) in real-time, meaning the information is generated with virtually no input from the user, eliminating the need for research chemists to be trained in calorimetry.
