How much would you want for the nitrate selective electrode?
I currently have it listed on Ebay.
Heres my email.
I'm interested in purchasing 3 photogates and 4 microphones from you. Would it be possible for you to send me pictures of these probes? I'd like to see the probe itself and its connection to make sure they would work with my equipment. Also, are the microphone probes the older or newer versions? My email is .
