Reply To: Continous HAB monitoring

There’s information on this page, in Section 6.2 about the holes for the cable glands: https://www.envirodiy.org/knowledge-base/building-an-envirodiy-monitoring-station/

As mentioned on that page, the 1/2″ NPT cable glands require you to drill a 23/32” hole and tap it with a 1/2″ NPT tap.  I don’t know what the diameter of the cable for your sensor is, but it’s probably between 0.2″ and 0.35″ so you can probably use McMaster-Carr part number 69915K54.   The larger gland that comes with the EnviroDIY kit is for cables 0.24″ to 0.47″ (part number 69915K53)  because of the rubber molded 3.5mm stereo plug on the end of the CTD cables.  If your Turner cable is larger than 0.35″ you’ll need to use the larger size.
