I designed this device by including its all electronic, mechanic and fitment details inside and out by near approach to 80s' tech.
This device helps analyze a fluid sample which is input by sampler tubes that I designed previously and informs user by the hazardious contamination levels by digital and analog indicators. It has short and long radio frequency transmitters to send reports to distant receivers. It has analog outs, USB outs and a glass observation tank for to see the contamination level by color change on the Contrast Liquid.
I also created a technical document and quick environment for the device.
