It's not about what sensor do I understand or not. What I'd like to know is which kind of sensors are inside this stations. I've worked with metal-oxide and electrochemical. I know there are infrared, but what are the top ones? What kind of sensors are the ones that can certify that there is X...

Good Morning guys! I'm trying to understand more about gas sensors. I know a lot about electrochemical and metaloxide sensors. I've faced all the limits that those sensors presents when you are using them outdoors. Now I'm wondering how the gas sensors stations can measure different gases...

Hi again, I've been digging around on how amperiometric sensors works and I found a big problem for me to understand.Scenario: 2 electrodes anode and cathode. Connected each other by an external circuit. We know oxidation potential of both. So we can calculate the potential difference. Now...

Hi, I'm trying to understand how an amperiometric cell with 3 electrodes(working, reference, counter. All of them inside a electrolyte) works. Till this point I get that when a gas reaches the working electrode a redox reaction happen and then it release electrons or charges that would cross...

Yes, it should. Cause it is for the study of the behaviour of the sensors when the temperature changes. But some device from 0 to 60 could work. Minus degrees is the ideal device. This is all about a name I can start looking with. I've found on some websites a lab equipment called incubator...

Budget is not a real problem, the cheaper the better but this is for a laboratory. I'm just going to make a budget. About the space, you are right I didn't mention it. I want to have a inner space about 50 cm H,W,D. I just want to place a vacuum chamber inside the incubator. Cheers

Hi all, I'm trying to find a special refrigeration device that can goes from -40 Degrees to 70 degrees. I need this machine for a laboratory to test sensors in differente temperatures. Does anyone knows where can I find something like that? Kind Regards Vicente

Hi, I'm working on my thesis and I need to calibrate some gas sensors that I'm building. I need controlled conditions(temp, RH and a known gas concentration) in order to calibrate the sensors. I'd love to know some idea to make a sealed box in which I trace and vary those parameter. I've...
