Chemical surveillance means that the concentration of different substances are measured over time and is mainly used in process industry in different ways. StromTech Sweden AB has developed the environmental robot Ebbot that performs sensor event-driven sampling and can bot log data and be remotely controlled. The robot takes samples when something actually happens!
The environmental robot is filled with chemical sensors that deliver environmental data in real time and is controlled from a cloud based instrument panel in your phone or computer. It is self-sufficient in electricity via solar panels, but is also equipped with batteries and ac adapter for dark environments. In contrast to algot, the environmental surveillance robot Ebbot has all sensors incorporated inside the robot. It also cleans and calibrates the sensors without manual handling.
The environmental surveillance system is designed to measure the following parameters, even if Ebbot to start with is limited to temperature, redox (ORP), pH and conductivity.
|Which light is absorbed by the water?
|Is the water luminous and which colour?
|Are there particles in the fluid?
|Which is the colour of the fluid?
|Saltiness of the water
|Acidity of the water
|Temperature in the water
|A measure of the oxidation level in the sample
|CO2 head space
|Elevated carbon dioxide above sample indicates degradation (headspace/gas)
|Total volatile organic substances in the air on site
|Total volatile organic substances from the sample (headspace/gas)
If equipped with optode chip the following is additonally measured:
The above at present up to 18 parameters is used as such or to determine whether Ebbot will take a sample to one of the 12 sample places in the machine. Sampling can be made according to a time scheduler or after a certain parameter whenever you like. Time resolution from 1 min.
* The robots are tracked and protected against theft
The robot can take up to 12 samples according to a predetermined schedule or be controlled to sample whenever you like. By its´sensors, it can also decide when best to sample so that pulses of emission can be collected for analysis at the laboratory. In that sense it performs a better sampling, based on sensor signals, than can be done manually by a human.
In addition no unnecessary samples are taken, that later on show the same concentrations during analyses at the laboratory. Instead the sampling frequency is adapted to changes in the environment that the robot senses via it´s sensors. It means that emissions are not undetected and a total environmental impact can be correctly determined.
Environmental surveillance services
The new technique is available as an environmental surveillance service that you book on demand. No purchase of equipment, no maintenance and no practical handling but just environmental data directly to you about the area you want to surveill. See the informative film below to learn how the service works.
