device that measures stray voltage

[regalangelfish]

Hello everyone...

I've contacted neptune systems several times and can't get a directresponse ti my question. Hoping I could get some answers here. I'm looking for a third party sensor or probe of some kind that would be able to read stray voltage in a reef tank similar to a multi meter would. Somehting that would plug into the IO breaker box and then apex can control devices based on programing. I curently use a leak detector which determins closed circuit so hoping something like this exists?

Please advise. Thanks...

:/ just plug in a voltmeter. Plug the ground probe (black) into a near by ground and dip the red probe in the water. That should give you a reading if there's any stray voltage.

There is nothing that will natively plug into the Apex or the BOB to do what you want... as far as I know.

Could you make something yourself that you could connect to the breakout box that would do what you want? Probably, if you're electrically inclined. But just remember that the Apex can only see an open/closed state of a switch through the breakout box. It can't read any milliamps or millivolts. So you'd have to make something that you'd stick in your tank, that would trip a switch or relay when the mV went above some threshold (that may or may not mean anything in real life). The Apex would then see the state of the switch through the breakout box, and you could then do programming based on that state.
