Hi, We are looking for a circuit to be made for a multi-channel voltmeter. The voltmeter must be low noise and cabable of measuring in the mV range so for example 0.01mV with good accuracy and stability and must be capable of measuring 5 channels simultaneously and then outputting these to a string which will be transmitted every 0.3 seconds via RS232/Twisted Pair/RS485 to be multiplexed by our system and then read using hyperterminal on a standard PC. one of the channels must be high impedance to allow for a long input cable length. Ideally the circuit board itself should be as small as possible with the dimensions around 15cm x 10cm.
We are looking for an electronics engineer who can design the circuit for something like this and then produce the prototype, we will be glad to pay for the services of anyone who can help us create what we want.
Please message me if you are interested in the work or know anyone who is.
