Keeper’s Note & Pro-Tip

Pro-Tip: If you’re building bioactive enclosures, wooden vivariums, or custom acrylic lids, use a standard hole saw bit to cut a flush circular opening. Press the gauge in for a sleek, built-in look that lets you check internal humidity and thermal gradients from the outside without opening the tank!
