    A must for any rebuild of repaired a Hantarex chassis.

    Great replacement for my failed HOT, got my Polo back up and running.

    It’s also works on the Hanterex 9100 series. I had one that was kind of flaky, it would test nice but under a real load it pooped out. So I got two of these just to be safe. Might go for some other monitors as well. A very hard to find part elsewhere. APR sucks only the highest best quality of products and this is no exception. If you’re not sure about your HOT. These are cheap enough to grab it to have it on hand if nothing else but oftentimes these are going out or already dead so grab yourself one or two 🙂
