splicing 2 pH probes together

Chrisrush · 08/09/2006, 01:59 PM

I'm getting a new BNC pH probe today but it is only 42" long. I need it to be around 6' or so. I have the old probe that I'm replacing. Can I cut the wire from the old probe and splice it into the new probe? Both are BNC connections.

Not easy to do because the outer conductor should be a braid. Might be best to aquire a female BNC end to your other cable. Most probes usually have a 10 foot cable anyway.

Thanks Loudell. I wish that this one had a 10' cable. The three probes that I've had have all been under 4'.

I would use an extension cable before I tried to splice the existing cable. Cutting the shield may or may not make a difference depending on the environmnet... but use use an extension of possible.
