This helps to maximize the quantity of sensors being tested and improves your testing by providing a dedicated radial groove for each sensor. Two 1/4 inch reference holes are also provided. An insulator plug is also included and helps to keep moisture out and the coolness in well. The insulator plug also includes plugged holes for the reference holes.
